The rubber compound obtained by mixing raw rubber or plasticated rubber with compounding agents by a rubber mixing mill is called mixed rubber. Mixed silicone rubber is based on linear high-polymer polyorganosiloxane (commonly known as raw rubber) with methyl or vinyl group-containing groups, and is formulated into a basic rubber compound by combining reinforcing fillers, extender fillers and additives that endow various properties. The main raw materials are methyl or vinyl raw rubber, and various materials such as silicon dioxide, crosslinking agent, structure control agent, coupling agent, etc. are added and mixed by a high-temperature internal mixer.
