​Polyaryl silicone resin

Polyaryl silicone resin is a copolymer containing only phenyl groups in the siloxane chain, and has excellent properties such as high heat resistance and strong oxidation resistance. Heat the polyaryl silicone resin plastic sheet to 400°C or 500°C in the air, and the phenyl group will not fall off from the silicon after several hours; heat it at 400°C for a longer time or place the polymer in a sealing The phenyl group can fall off by co-heating with dilute acid or bromine water in the sealed tube.
