PPX Resin

What is PPX Resin?

PPX resin is a blend of polyphenylene ether (PPE) and polystyrene. The PPX blends are unique in that unlike other resin systems, the two polymers are totally compatible in all proportions. Because of this unique characteristic, polyphenylene products can be made with heat distortions that range from a low of 170 F (styrene) to a high of over 350 F (PPE). With different ratios of the two resins, and the incorporation of additive packages for impact strength (non-brominated FR, reinforcements etc.) a family of products can be made featuring UL-VO to UL HB and UL 5V, high stiffness, and or high impact and process ability. Both resins are inherently hydrolytically stable that makes the blends suitable over a wide temperature and humidity range.

The polyphenylene products exhibit a unique feature of retention of tensile and flexural strength and low creep even at elevated temperature.

Impact strength of polyphenylene family of products is typically unaffected by factors such as humidity and only slightly by temperature and wall thickness. A key advantage of PPX resins is that they maintain their impact strength, even at sub-zero temperature.

    Additives, Modifiers, and Reinforcing Agents:
  • Additives – UV stability, easy release (mold releases), colorants, and other stability additives
  • Modifiers – Flame retardants, impact modifiers, flow enhancers
  • Reinforcing Agents – Glass fibers, mineral fillers

PRODUCT Q&As

Q. What are the advantages and disadvantages of modified polyphenylene ether resins?
A. Polyphenylene ether (PPE), which is also called polyphenylene oxide (PPO™), is a thermoplastic material offering high heat resistance, excellent dimensional stability, low moisture absorption and good electrical properties. Blending PPE with high-impact polystyrene (HIPS) yields products that span a wide range of heat deflection temperatures (HDTs). These blends are easily processed and have a good balance of physical properties. With suitable compatibilization technology, PPE can also be blended with either nylon 6,6 or nylon 6. Nonhalogenated flame retardants can be added to PPE/HIPS blends to produce flame retardant grades. The main disadvantage of PPE is its poor melt processability, due in part to a very high glass transition temperature and high melt viscosity. To avoid oxidative degradation from high processing temperatures, PPE is blended with PS. The compatibility between the two materials was discovered during development in the 1960s.
Q. Is PPE a thermoplastic?
A. Yes, polyphenylene ether blends (PPE or PPO) are engineering thermoplastics that can be injection molded or extruded. This class of polymers contain phenolic monomers attached via an ether linkage. Blending with impact-modified PS yields opaque resins that can exhibit a wide range of chemical, thermal and mechanical properties.
Q. Is PPE amorphous or crystalline?
A. Polyphenylene ether is an amorphous material. Through compatibilization technology, blends of PPE with crystalline resins can be produced to provide alloys that offer properties of both amorphous and crystalline materials.
Q. What applications are PPE used for?
A. Modified PPE is used in applications requiring dimensional stability, heat resistance and toughness. Examples include structural parts, electrical and electronics components, automotive and appliance parts, wire and cable, and water management equipment. This material can also be used in medical devices and instruments requiring steam sterilization. The surface of the material can be printed, hot stamped, painted or metallized.
