What is extrusion silicone products?
Silica gel is a kind of special rubber, crosslinking has good mechanical strength, wear resistance and high temperature resistance, it belongs to thermosetting rubber, after vulcanization heating will not melt, the temperature is too high will burn, complete combustion products for water and silica. 2. They are different in the analytical structure: silica gel is the elastic body connected by the main chain silicon oxygen bond, and the side chain is generally methyl, namely CH3. TPE is a thermoplastic elastomer, consisting of styrene, olefin and polyurethane. The main difference between the two molecular structures is that one is SI02 structure and the other is CC structure.
