PPE+ PA

Polyphenylene ether (PPE) is a thermoplastic, linear, non-crystalline polyether obtained by oxidative polycondensation of 2,6-dimethylphenol in the presence of a complex catalyst. Polyphenylene ether, also called polyphenylene oxide, is usually mixed with polystyrene to improve its strength and processability. Polyphenylene ether has excellent electrical properties, remarkable acid and alkali resistance, and is processable on conventional extrusion and injection molding equipment. PPE is easily attacked by some hydrocarbons, although it is resistant to many chemicals. Polyphenylene ether has excellent dimensional stability, low moisture absorption, and high mechanical and dielectric strength. In 1965, polyphenylene ether was introduced as polyphenylene oxide (PPO) by General Electric Co. in the USA and by AKU in the Netherlands. The PPE and PPE+ PA binders for plastics presented here are used for welding and joining parts and elements made of plastics with these markings. The designation P / E is sometimes used on parts of French cars.
