For decades, the engineering resin market has been dominated by a few household names. If you design medical devices or electrical components, you know the list: Cycoloy, Noryl, Valox, and Xenoy.
These SABIC products have set the standard for performance. However, relying exclusively on global giants for your supply chain comes with risks.
In today’s manufacturing landscape, agility is just as critical as mechanical properties. Engineers are increasingly facing extended lead times, restrictive Minimum Order Quantities (MOQs), and a lack of flexibility.
When a production line is down, the brand name on the bag matters much less than the availability of the resin inside it.
The big question is: Can you find a “drop-in” replacement that matches the performance of these major brands without the supply chain headaches?
The answer is yes. We do it by focusing on the underlying chemistry rather than the logo.
Why Seek Alternatives?
The primary driver is risk mitigation. We have all seen the chaos caused when a massive supplier declares force majeure. If your production line depends on one brand from one source, you are stuck. Diversifying your supply chain is the only way to protect your business.
There is also the issue of priority. Major suppliers operate on volume. If you aren’t ordering automotive-level quantities, you often fall to the back of the line.
Finally, there is customization. Large suppliers sell what is in the catalog. They aren’t built to develop custom formulations. Finding an agile alternative partner puts you back in the driver’s seat, allowing you to prioritize your technical needs over a giant supplier’s rigid schedule.
Mapping the Alternatives: Brand Name vs. Chemistry
When you peel back the label, these proprietary names represent specific chemical families. Understanding the base chemistry allows you to source based on performance data.
The Alternative to Cycoloy (PC/ABS): A blend of Polycarbonate and ABS. It combines the heat resistance and impact strength of PC with the processability of ABS. It is the standard for impact-resistant housings.
The Alternative to Noryl (PPO / PPE): A modified Polyphenylene Oxide. Known for hydrolytic stability (it absorbs very little moisture) and excellent dielectric strength. It is a powerhouse for electrical applications like solar junction boxes.
The Alternative to Valox (PBT) and Xenoy (PC/PBT): PBT offers chemical resistance and dimensional stability. When blended with PC (PC/PBT), it gains toughness. These are critical for environments requiring resistance to harsh chemicals.
Specialized Applications: Medical & Electrical
Non-Invasive Medical Devices Durability and biocompatibility are the challenges here. Devices like surgical instruments need to withstand drops (requiring PC/ABS) and aggressive hospital disinfectants (requiring PC/PBT). Furthermore, the resin provider must match “medical white” colors with absolute precision, lot after lot.
Critical Electrical Components Safety is the non-negotiable factor. Engineers need materials that insulate well and resist burning. PPO compounds are the industry standard here due to low moisture absorption. Sourcing an alternative doesn’t mean skipping safety; it means finding a partner who has done the legwork to certify materials to UL 94 flammability standards.
The Polymer Resources Advantage
We are the agile alternative to the industry giants—the fighter jet versus the airliner.
Large suppliers are built for volume; we are built for speed, flexibility, and specialized support.
Speed: We cut lead times significantly so you aren’t waiting months for material.

The U.S. resin market is entering a new era of cost pressure. Actually, we’re in the midst of it, reasonably speaking.
With tariffs of 10–25% imposed on imported plastics and engineering resins from countries such as China, Canada, and Mexico, many manufacturers are reevaluating their sourcing strategies.
For OEMs, molders, and procurement teams, the difference between domestic and imported resins in 2025 could mean the difference between protecting margins or facing unexpected cost spikes.
Polymer Resources, with all manufacturing based in the United States, delivers a cost-stable, tariff-free solution that ensures better pricing predictability. But that’s not the case across the industry.
Today, we’ll explore the impact the current tariff climate is having and what it means for a variety of consumer industries and executives tasked with purchasing resins.
Understanding the Tariff Impact on Engineering Resins
Our logical first step is to delve into a basic understanding of what’s happening in the environment.
Simply put: Over the past several months, the U.S. government has expanded tariffs on imported goods, including engineering plastics. We’re confident you’ve seen tariffs making the news, but you may not be entirely aware of the specifics involved with resins.
In early 2025, the U.S. enacted broad import tariffs: 25% on goods from Canada and Mexico, and an additional 10% on imports from China, layering on top of pre-existing trade duties. These import duties now amount to substantial cost surcharges for foreign resin suppliers and their customers.
Several supply chains have already responded. For example, price inflation linked to tariffs is increasingly being passed from manufacturers to end consumers, contributing to a broader wave of cost-push inflation across U.S. markets.
Which Resins Are Most Affected by Import Tariffs?
We know international resins are feeling the heat of tariffs. Now, let’s break things down by specifics.
Polycarbonate (PC)
At about 70% domestic production, the North American PC market remains largely insulated from tariffs, meaning price volatility is limited even amid tariff pressure.
While PC supply remains stable, other resins tell a different story. Let’s look at which are most vulnerable to tariff pressure.
ABS Resin
With 35–40% of supply imported, ABS is significantly affected. Tariffs on imported ABS translate into notable cost increases, giving domestic suppliers a competitive edge.
Nylon 6 & Nylon 66
Production of Nylon 66 is strong domestically, but reliance on imported Nylon 6 remains moderate. Tariffs increase the risk for buyers dependent on foreign nylon supplies.
PBT & Specialty Resins
North America imports around 70% of PBT demand, making these materials very sensitive to tariff-driven price fluctuations.
Blends & Compounds (e.g., PC/ABS, PC/ASA, PPE blends)
Imported compound blends face the same tariff penalties as their base resin components. By contrast, manufacturers like Polymer Resources can avoid these tariffs through in-country compounding.
How Tariffs Reshape Sourcing in Key Industries
Consumer Goods
The consumer goods sector is highly price sensitive, especially in areas like internal and external housings, HVAC components, and FDA-compliant applications.
When imported resins face tariff surcharges of 10–25%, the economics of these products shift dramatically. And not for the better.
For OEMs and molders, a sudden increase of $0.20–$0.30 per pound in resin costs can make the difference between a competitive product and one that is priced out of the market. By sourcing domestically from suppliers like Polymer Resources, consumer goods manufacturers can protect against cost volatility while ensuring consistent performance and regulatory compliance.
Polymer Resources provides FDA-compliant, domestically manufactured compounds that help brands stay competitive.
Medical Devices
Non-invasive and diagnostic medical devices must meet stringent FDA and ISO requirements.
In this industry, consistency, certification, and supply reliability matter just as much as cost.
Tariffs on imported resins not only raise prices but can also complicate compliance if sourcing shifts between suppliers. Domestic production helps eliminate these risks. Polymer Resources’ U.S.-made medical-grade engineering resins give device manufacturers a predictable, tariff-free supply chain while adhering to strict healthcare standards.
By sourcing from a U.S. partner, OEMs gain not just compliance, but tariff-free stability.
Transportation
The transportation industry — spanning automotive, heavy truck, agriculture, and marine — relies on engineering resins for critical components such as battery housings, lighting systems, and structural parts. Tariffs increase the cost of imported materials, directly affecting the bottom line for OEMs that already operate in a highly competitive, margin-sensitive market. By sourcing from a domestic supplier, transportation manufacturers can avoid unpredictable tariff costs, reduce shipping expenses, and ensure on-time delivery for just-in-time production environments.
Building & Construction
Large-scale construction projects require materials with specific performance additives, such as UV stability, flame retardancy, and impact resistance. Imported engineering resins used in building applications are especially vulnerable to tariff-driven cost spikes, which can cascade across multi-phase projects and inflate budgets. Domestic resin suppliers like Polymer Resources provide tariff-free, custom-formulated compounds, helping builders and contractors stay on budget while still meeting rigorous performance and safety standards.
Frequently Asked Questions (FAQ)
Are all resins subject to U.S. tariffs in 2025?
Not all. Common commodity resins like polyethylene and polypropylene have sometimes been exempted, but engineering resins such as ABS, Nylon 6/66, and PBT face significant tariffs, particularly when imported from China, Canada, or Mexico.
How much can tariffs increase resin costs?
A 10% tariff has historically added about $0.10–$0.23 per pound to resin pricing. At 25%, the increase could be closer to $0.30–$0.40 per pound, depending on the material and supply chain.
Why do domestic resins cost less under current tariffs?
Resins manufactured in the U.S. are not subject to import duties, so their prices don’t include the 10–25% surcharge that international suppliers must pass along to customers.
Which industries are most affected by resin tariffs?
Industries with heavy reliance on engineering resins—such as consumer goods, medical devices, transportation, and construction feel the impact most. These sectors use materials like ABS, Nylon, and flame-retardant blends that are often imported.
What makes Polymer Resources different from global resin suppliers?
Polymer Resources manufactures and compounds all resins in the United States, eliminating tariff surcharges, reducing lead times, and offering custom formulations tailored to OEM and molder requirements.
Conclusion: Choosing Cost-Stable Resins in a Tariff-Heavy Market
The 2025 tariff environment makes imported resins less predictable and more expensive. For procurement and engineering teams, domestic sourcing is no longer just a patriotic choice — it’s a strategic business decision.
By working with Polymer Resources, OEMs and molders gain tariff-free materials, dependable supply, and the flexibility of custom formulations. In a global market shaped by tariffs and supply chain risk, U.S.-made resins offer the clearest path to cost savings and stability.

When it comes to patient safety and device reliability, few people ever talk about the materials used to manufacture widely used non-invasive medical devices. But, they should. From diagnostic housings to reusable handles and even connectors, every component in a medical device needs to balance mechanical performance, biocompatibility and regulatory compliance. And all while meeting the design and sterilization demands prioritized in clinical environments.
While there are a number of engineering resins available, polyetherimide (PEI) and polyphenylene oxide (PPO) stand out for their exceptional strength, heat resistance, and stability. So we’re going to focus on those today.
As the medical industry continues to evolve towards safer, smarter, and more sustainable materials, choosing the right engineering resin becomes a critical decision. Understanding the distinct benefits of PEI and PPO and how they compare to other commonly used polymers goes a long ways in helping medical device engineers better design for safety and longevity, as well as compliance.
Let’s dig in.
Why PEI and PPO Are Ideal for Non-Invasive Medical Devices
Non-invasive medical devices have to do more than just function (though that’s important), they have to perform reliably, often under tough conditions. From frequent sterilization to exposure to harsh disinfectants, these products need materials that won’t crack, warp, or degrade over time. That’s where polyetherimide (PEI) and polyphenylene oxide (PPO) come in. Both offer a level of performance that goes beyond what’s possible with general-purpose plastics.
PEI is known for its ability to withstand high heat, maintaining its structure even during repeated autoclave sterilization. In case you’re curious, “autoclave sterilization” is a high temp, high pressure steam process used to kill bacteria, viruses, fungi, and spores. If materials are weak or questionable, such high heat can degrade the materials pretty fast.
PEi delivers the kind of dimensional stability and stiffness engineers count on when designing reusable components. Again, think heat.
PPO, on the other hand, brings excellent hydrolytic stability and chemical resistance. That makes it a strong choice for products exposed to moisture, cleaning solutions, and temperature changes.
Both PEI and PPO also maintain their form in humid environments (think steam again) and can be formulated to meet key medical standards like ISO 10993 or USP Class VI for biocompatibility. That means they’re safe for skin contact and patient handling which is essential for non-invasive devices used every day in clinical settings.
When compared to more common materials like polycarbonate (PC), acrylonitrile butadiene styrene (ABS), or polyvinyl chloride (PVC), PEI and PPO stand out. While those resins work well for lightweight housings or disposables, they tend to lose shape under high heat or after multiple sterilization cycles. PEI and PPO hold up longer, keeping their integrity and performance through repeated use.
For manufacturers looking for a balance of safety, durability, and design flexibility, these resins deliver by helping bridge the gap between standard thermoplastics and the high-performance demands of modern medical devices.
Key Applications in Non-Invasive Medical Devices
PEI and PPO resins aren’t just strong on paper, they prove their value in real-world medical settings every day.
Their ability to resist heat, chemicals, and wear makes them reliable choices for components that must perform consistently, even after repeated cleaning or sterilization.
Here are some of the most common areas where these materials stand out.
Diagnostic Equipment and Device Housings
From blood analyzers and patient monitoring systems to imaging units and centrifuge housings, non-invasive diagnostic equipment depends on materials that can handle constant use without losing dimensional accuracy. PEI and PPO provide the rigidity and thermal stability needed to protect sensitive electronics while keeping weight and manufacturing costs under control. Their smooth surface finishes also make them easier to clean, a key advantage in clinical environments where hygiene is non-negotiable.
Reusable Handles, Trays, and Connectors
For reusable surgical tools, autoclave trays, and instrument handles that undergo repeated sterilization, PEI is often the go-to choice.
It keeps its form and mechanical properties even after dozens of sterilization cycles. PPO also performs well in connectors, tube fittings, and ergonomic grips where moisture and repeated handling come into play.
Both materials can be custom-formulated to improve grip, color stability, or resistance to stress cracking.
Fluid Management and Delivery Systems
When it comes to non-implantable devices that move or manage fluids, like pumps, valves, or external delivery cartridges, PEI and PPO deliver consistent performance.
Their low moisture absorption helps maintain precision fit and function, while their chemical resistance protects against degradation from cleaning solutions or reagents.
These examples show why PEI and PPO resins have become dependable materials for engineers designing next-generation medical devices that prioritize safety, reliability, and longevity.
Design and Processing Considerations
Selecting the right resin is only part of the equation.
How it’s processed and designed into a device can make or break overall performance.
PEI and PPO both offer excellent processability for complex geometries, but there are a few considerations that medical device engineers should keep in mind to get the most out of these materials.
Moldability and Dimensional Precision
Can it shape? And stay that way?
PEI and PPO resins allow for tight tolerances and precise molding, which is critical when parts need to align perfectly in diagnostic systems or reusable tools. Their inherent stiffness helps prevent warping during cooling, while their low moisture absorption keeps dimensions stable after production. These traits make both materials ideal for components that require repeatable accuracy, such as instrument housings, pump components, and sensor enclosures.
Color Matching and Transparency Options
While performance often takes center stage, aesthetics matter too; especially in medical environments where color coding, clarity, and clean appearance all contribute to usability and brand consistency.
PEI offers natural transparency with a slight amber hue, while PPO can be easily pigmented for opaque or translucent applications.
Polymer Resources can custom-compound both materials to achieve the exact color, opacity, or finish required, without compromising performance or regulatory compliance.
Maintaining Compliance Through Processing
It’s important to note that not all grades of PEI or PPO are created equal.
Medical-grade formulations from suppliers like Polymer Resources are designed to meet FDA and ISO requirements, including biocompatibility and lot-to-lot consistency. Proper drying, controlled processing temperatures, and post-mold conditioning help ensure these resins retain their mechanical properties and compliance through every production cycle.
From design to manufacturing, the key takeaway is simple: when processed correctly, PEI and PPO resins deliver the dimensional accuracy, sterilization resistance, and clean aesthetics that non-invasive medical devices demand.
Sustainability and Supply Chain Reliability
Because both materials are reusable and recyclable, they help extend the lifespan of medical components and reduce the need for frequent replacements. Their ability to endure multiple sterilization cycles also supports sustainability by cutting down on disposable plastics. For OEMs pursuing eco-conscious product lines, this can translate into lower overall material consumption without compromising safety or compliance.
On the production side, Polymer Resources manufactures and compounds materials domestically, which helps reduce lead times and minimize the supply chain risks associated with overseas sourcing (particularly related to tariffs).
Consistent, U.S.-based production also ensures that each formulation maintains the same high quality and regulatory traceability, critical for customers operating in the medical sector.
With PEI and PPO, manufacturers can count on a reliable supply of medical-grade resin solutions that perform, comply, and align with long-term sustainability goals.
