Silicone Gum is an un-sulfurized (un-crosslinked) basic polysiloxane, which contains a large number of silicon and oxygen atoms, as well as a small amount of organic groups in its molecular chain. This special structure endows silicone gum with excellent properties such as temperature resistance, aging resistance, and corrosion resistance.

Silicone Rubber is a type of polymer elastomer, mainly composed of silicon oxygen bonds forming the main chain, with organic groups attached to the side chains. This structure gives silicone rubber good elasticity and flexibility, as well as excellent temperature resistance, weather resistance, and electrical insulation properties.
