The mixed silicone rubber is a basic rubber prepared based on methyl or linear high polymer polyorganosiloxane (commonly known as raw rubber) containing vinyl groups, combined with reinforcing fillers, incremental fillers and additives with various properties.

The main raw materials of special mixing compound are methyl or vinyl raw rubber, silica, bridging agent, structure control agent, coupling agent and other materials, which are mixed by high-temperature internal mixer.
