Polyphenylene Oxide Ether Blends PPO and PPE

Modified polyphenylene oxide (PPO) and polyphenylene ether (PPE) resins were first commercialised in the mid 1960s. PPO and PPE are similar in chemical composition and properties 

Elastic modulus (MPa) (tensile with 0.2% water content) 2139-2622 6900-8970 

Modified PPO/PPE is used for its outstanding properties in a broad range of applications such as automotive, fluid handling (water softener valves, and water pump components), power tools and enclosures (VDU and computers), TV components, washing machine components, electrical insulation and telecommunications.

Polymer blends can be subdivided into two kinds those of compatible and those of incompatible polymers. Real compatibility is an exception (see 9.1) an example is PS with PPE (polyphenylene ether, also called PPO, polyphenylene oxide). These two polymers can be blended with each other on such a small scale that it really looks like molecular miscibility. This blend shows, therefore, only one single glass transition. 

Chapter 9, Polyphenylene Ether Blends and Alloys, from GE Plastics describes traditional and new polyphenylene-ether grades based on GE Plastics Noryl . GE Plastics originally invented polyphenylene ether (PPE), its blends and alloys, and PPO polyphenylene oxide. Noryl is typically...
