Polyphenylene oxide (PPO) is a yellowish plastic, which can be modified with glass binding and is suitable for injection molding and extrusion. This plastic is often used in the electrical industry, in pumps, impellers, kitchen appliances, coil stems and water filters. The phenylene oxide plastic has a high operating temperature, is dimensionally stable, resistant to hydrolysis and has good creep resistance, etc.
Polyphenylene oxide (PPO) has a good balance of thermal, electrical and mechanical properties, which makes it suitable for a variety of applications, especially when some of its excellent properties can be used to the full. Compared to other engineering resins, PPO has a higher resistance to heat deformation 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 properties, 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 a gradual decrease in modulus as temperature increases.
PPO goes by the trade name Noryl®
