Poly(p-phenylene oxide) or poly(p-phenylene ether) (PPE) is a high-temperature thermoplastic. It is rarely used in its pure form due to difficulties in processing. It is mainly used as a blend with polystyrene, high-impact styrene-butadiene copolymer, or polyamide. PPO is a registered trademark of SABIC Innovative Plastics IP B.V. under which various polyphenylene ether resins are sold.
PPE blends are used for structural parts, electronics, household and automotive items that depend on high heat resistance, dimensional stability, and accuracy. They are also used in medicine for sterilizable instruments made of plastic. The PPE blends are characterized by hot water resistance with low water absorption, high impact strength, halogen-free fire protection, and low density.
This plastic is processed by injection molding or extrusion; depending on the type, the processing temperature is 260-300 °C. The surface can be printed, hot-stamped, painted, or metalized. Welds are possible by means of heating elements, friction, or ultrasonic welding. It can be glued with halogenated solvents or various adhesives.
This plastic is also used to produce air separation membranes for generating nitrogen. The PPO is spun into a hollow fiber membrane with a porous support layer and a very thin outer skin. The permeation of oxygen occurs from inside to out across the thin outer skin with extremely high flux. Due to the manufacturing process, the fiber has excellent dimensional stability and strength. Unlike hollow fiber membranes made from polysulfone, the aging process of the fiber is relatively quick so that air separation performance remains stable throughout the life of the membrane. PPO makes the air separation performance suitable for low temperature (35-70 °F; 2-21 °C) applications where polysulfone membranes require heated air to increase permeation.
