TPE is a general term for a variety of elastomer materials that have rubber elasticity at room temperature and can melt and flow at high temperature.
Silica gel is a kind of special rubber, after crosslinking has good mechanical strength, wear resistance and high temperature resistance, it belongs to thermosetting rubber, after vulcanization and reheating will not melt, the temperature is too high will burn, the product of complete combustion is water and silica.
