Polycarbonate Panels – Various Applications and Benefits

Polycarbonate Panels – Various Applications and Benefits

Composed of thermoplastic polymers, Polycarbonate panels are usually found in several industrial applications. Polycarbonate is a polymer which includes numerous identical units of bisphenol A which are interlinked by carbonate. This type of polymer liquefies when heated and converts into a glassy state when cooled. Polycarbonate panels offer high impact resistance and protection from cracking, breaking or chipping. These panels are available in different sizes, shapes and colors.

The polycarbonate panels are reasonably lightweight and usually available in single, double and triple wall panels. To achieve the desired shape and finish, the polymer is melted and forced through a die. Polycarbonate panels are processed using the following main processes like injection molding and extrusion.

  • Injection molding: Initially the polymer is heated, melted and then pressed into a mold, so that it can take the desired shape of the mold. Usually used to manufacture single end products, injection molding is highly effective.
  • Extrusion: The polycarbonate is melted and pressed through an orifice which allows the molten polymer to take the shape of the die. Most manufacturers use this process to produce large sheets, pipes and profiles.

There are several benefits associated with the use of polycarbonate panels which are usually used in glazing applications.

  • High durability and strength: The polycarbonate panels are used in a wide range of industrial applications. The high durability features of the panels allow it to withstand harsh climatic conditions, resistance to chemicals and abrasion.
  • Highly cost-effective: There are several factors which decide cost effectiveness like installation cost, maintenance cost and the aspect of time. Polycarbonate panels are generally expensive, so what makes them cost effective? They offer longevity which means that they maintain their condition and shape for several years, thereby providing complete value for money.
  • Greenhouse construction: Polycarbonate panels are in great demand for greenhouse construction. This is because, the panels fulfill almost all requirements of any greenhouse glazing panel. By enhancing light diffusion and guaranteeing longevity, polycarbonate panels are popular among farmers.
  • Effective design: The polycarbonate panels are available in different designs and finishes. They tend to offer a mixed variety of several properties like energy saving, moderate light transmission, insulation properties, longevity, etc.

In case of residential buildings, these panels are usually used for awnings and overhead shades because they provide protection from harmful UV rays and easily withstands strong forces. In comparison to other type of panels made with glass or plastic, the polycarbonate panels are extremely lightweight which translates to lower transport and labor costs.

Nylon 66 Polymer – Step Reaction Polymerization

Nylon 66 Polymer – Step Reaction Polymerization

Nylon-66 is a polyamide fibre which is manufactured by a process that involves step growth polymerization and condensation polymerization. The generic term used to define long chain synthetic polyamides is Nylon. One of the key members from the group of poly-condensation products of acids and diamines, Nylon-66 has great abrasion resistance, strength andresistance towards heat, water and chemicals.

When compared with Nylon 6, Nylon-66 is a superior version due to its higher melting point, greater dimensional stability and a more compact molecular structure. With a guarantee of excellent performance in high speed spinning processes, it also has good UV light-fastness and dye wash fastness.

There are different ways of referring to Nylon-66 as Nylon 6-6, Nylon 6,6 etc. The Nylon 66 polymer is made of hexamethylenediamine and adipic acid which provides Nylon 66, a total of 12 carbon atoms in each repeating unit.

Availability of Nylon 66

Easily available in both sheet and rod form, Nylon 66 has a wide range of applications. Generally the rods are available from 4mm-200mm diameter and the sheets are from 5mm thick to 100 mm thick.

Manufacturing Process

The ingredients i.e. Hexamethylenediamine and adipic acid are combined with water in a reactor. The outcome of this process is the nylon salt which is sent for evaporation which removes any excess water. The nylon salt is then passed through a reaction vessel where a continuous polymerization process makes molten Nylon 6,6. The molten nylon is then passed through a spinning process, with Nylon-66 extruded and sent via spinneret. Once the nylon is air cooled to form filaments.

Favourable Temperatures

Nylon-66 can operate at temperatures exceeding 100 °C, where the maximum limit is 160 °C and generally allowed only for short term applications.

Various Applications

Probably, one of the most important and popular engineering plastic, it can be utilized for a wide range of applications like bearings, gears, pulleys, screws, bushes etc.

Around 55 years back, Remington Nylon 66 took polymers to a new level with the introduction of world’s first mass produced rifle made from something other than wood.


The long molecular chains of Nylon 66 results in higher number of hydrogen bonds which also makes it extremely resilient. Being an amorphous solid, it is slightly soluble in boiling water and has large elastic properties. It offers immaculate dimensional stability, high melting point and excellent abrasion resistance. With the use of reinforcements, the physical strength of Nylon-66 can be improved multiple times. Few popular applications of Nylon includes carpet fibres, swimwear, parachutes, tyres, ropes and air bags etc.

A Practical Guide to choosing the Best Engineering Thermoplastics

The Advantages to the Customer of Multiple Warehouses

The Advantages to the Customer of Multiple Warehouses

There are many techniques and theories when it comes to warehousing. Companies can choose between operating between single centrally located warehouses and operating multiple warehouses throughout a region or a country. In multiple warehousing systems, companies spread out to cover territories and be easily accessible to customers. It offers many benefits as compared to single centrally located warehouse systems. There is plenty of debate regarding which is the most efficient and effective. Ultimately, it all comes down to the satisfaction of customers. Depending on the customer satisfaction, it is more appropriate to have multiple warehouses.

Imagine a customer trying to get a product to the middle of Texas when there is only one single located warehouse in New York. While the product would eventually get there, would you lose anything by having it take long? When you have multiple warehouses, there are clear advantages that make you reliable to customers in the long run. From saving on transportation costs to making clients happy, the use of multiple warehouse system just makes sense.

Here are the advantages of having multiple warehouses:

  • Quick delivery: with multiple warehouses, delivery time can be cut down pretty dramatically, meaning that you can move more products at a quicker pace. Instead of customers waiting for products to arrive from one single centrally located warehouse, their orders will be shipped quickly from various warehouses, meaning their purchased products arrive quickly.
  • Low transportation costs: because products will spread out over a larger area when you have multiple warehouses, the cost of delivering purchased products significantly decreases as warehouses are in the vicinity of customers.
  • Easy accessibility: instead of having your products in one place, they will be in multiple places, meaning that if a customer needs a product, the entire process becomes much easier. Having your products spread out means having easy access to multiple warehouses rather than one centrally located warehouse.

Other advantages of multiple warehouses are:

  • Elimination of middlemen in between manufacturers and ultimate consumers.
  • They avail the advantages of bulk purchasing.
  • Uniformity of prices and quality of products sold is maintained at all warehouses.
  • If one warehouse has short supplies, then it can be immediately replenished from another warehouse so that customers can easily access products.
  • There are low operating costs hence prices are not increased to cater for operations.
  • There are flexibilities of operation in such warehouse systems.
  • If one warehouse is closed, customers can still access products in other warehouses as compared to single centrally located warehouses where if closed, there are no more operations.
