Details 

 PPO-dimethyl-phenol polymer. Also known as polyphenylene oxide. Abbreviation PPO. Structure of the glass transition temperature of about 210 ℃, melting temperature of 257 ℃, density of 0.96 ~ 1.06 g / cm 3. Practical molecular weight polyphenylene ether 2 to 5 million, about 50% crystallinity. The most prominent advantage is highly resistant to water and steam resistance. 132 ℃ high-pressure steam in the container handle 200, tensile and impact strength did not change significantly, in addition it also has good dimensional stability, creep is small, high insulation characteristics, long-term use temperature of -127 ~ 120 ℃ No interruption of work load up to 200 ℃, and the general level is very thermosetting plastics, polyphenylene ether by the 2,6 - dimethyl phenol in the copper salt (such as cuprous chloride) and amine bonding catalyst, in the air or pure oxygen for oxidative coupling polymerization. Easy processing of polyphenylene ether molding, extrusion, injection and molding can be. Instead of stainless steel for the manufacture of medical devices, able to withstand steam sterilization, but also for mechanical and electrical components, insulation materials. Polyphenylene oxide and polystyrene blends modified material in the United States trade name Noryl, and can add 20% to 30% glass fiber, carbon fiber enhancements, is an excellent engineering plastics and insulation materials
