Polyphenylene ether (PPS) is a kind of thermoplastic resin with high temperature resistance. The amorphous type has excellent heat resistance, strength and dimensional stability of polyphenylene oxide (PPO) and polyamide with excellent chemical resistance, high fluidity and semi crystalline coating the mixture of resin (PA), is a kind of high strength, high toughness, high heat resistance and chemical resistance engineering plastic alloy. Rizhisheng PPO/PA alloy material with low density, high strength and high modulus; have excellent high temperature resistance and low temperature performance, to meet different application environment requirements; has excellent chemical resistance and dimensional stability; has good low mold shrinkage rate; excellent surface finish.
