PPO Thermoplastic Material at Aline Components Custom Plastic Injection Molding and Manufacturing Company

Aline Components, a custom plastic injection molding and manufacturing company, offers polyphenylene oxide (PPO) thermoplastic material for customers who want custom plastic parts or components that are rigid, opaque, and have good dimensional stability in elevated temperature and humidity conditions. PPO is ideal for a broad base of applications, including but not limited to automotive, industrial, and commercial. We recommend using PPO when good hydrolytic stability and high strength is a must.

Customers from all market segments internationally, nationally, and regionally in Bucks County and Philadelphia, Pennsylvania, New Jersey, Delaware, and Maryland are choosing polyphenylene oxide products for their assembly or subsystem needs. To provide customers with high quality at an exceptional value, Aline Components buys only the best PPO plastic materials directly from major resin suppliers. At Aline, we feature the Noryl® family of polymers manufactured by General Electric Plastics, which combine the inherent benefits of amorphous PPO resins with outstanding dimensional stability, good processibility, and low specific gravity.

What is PPO Thermoplastic Material?

PPO is a raw polymer that is naturally opaque and demonstrates superior high performance properties. PPO can be substantially modified for demanding applications by integrating rubber impact modifiers and other alloying agents to the original formulation. Standard PPO is difficult to process, however, when the right blend is achieved, plastic injection molding and manufacturing couldn’t be easier. Noryl® is often referred to as a type of PPO, but in fact, it is a blend of both PPO and polystyrene.

PPO Thermoplastic Properties

Polyphenylene oxide has a good balance of thermal, electrical, and mechanical properties, which make it suitable for a variety of applications, especially when some of its excellent properties can be used to their full extent. When compared to other engineering resins, PPO has a higher heat deformation resistance and is available at a lower cost. PPO thermoplastics have a wide high performance temperature range from –40 to 130°C. With low moisture absorption characteristics, PPO exhibits exceptional dielectric properties even in high temperature and humidity environments. Polyphenylene oxide has high stiffness as well as tensile and flexural strength with only gradual reduction in modulus as temperatures increase.

Advantages of PPO Plastic Include:
  • High strength 
  • High heat distortion resistance
  • Outstanding hydrolytic stability
  • Good creep resistance
  • Resistance to stress cracking
  • Resistance to weathering
  • Excellent chemical resistance
Benefits of PPO Thermoplastic

Outstanding dimensional stability and distortion resistance at elevated temperatures as well as a broad temperature range are two primary reasons for using PPO. Polyphenylene oxide has excellent hydrolytic stability with water absorption rates among the lowest of all thermoplastic engineering resins. Due to this materials high heat resistance, it offers good creep resistance, particularly high temperatures. Its resistance to creep is made even better with the inclusion of various fillers and additives. Also, PPO provides an excellent resistance to weathering (black grades demonstrate the best UV resistance) and an assortment of chemicals such as acids, bases, alkalis, most salt solutions and alcohols, and numerous cleaning agents.

As a leading plastic injection molding and manufacturing company and an international supplier of custom plastic parts or components, Aline Components offers modified polyphenylene oxide thermoplastics to match the specifications of customers from all industries. PPO can be designed to replace stamped steel, die cast metal, and brass in various functional assemblies. Discover how our thermoplastic resins can be tailored to your application requirements.
