The preparation of silicone rubber mainly involves the mixing of linear polydimethylsiloxane with crosslinking agents, reinforcing fillers, and other compounding agents, and the formation of elastomers through vulcanization process. Its development process can be traced back to the 1940s, when it was first developed and put into production by foreign countries. China also successfully achieved industrial production in the early 1960s.


Modification research improves performance: Although silicone rubber has excellent properties, there are still shortcomings such as low tensile strength and tear strength, poor acid and alkali resistance. To this end, researchers have carried out extensive modification work, such as copolymerization of organosilicon with other monomers or polymers, addition of reinforcing fillers, etc., to enhance the comprehensive performance of silicone rubber.


New varieties continue to emerge: With the development of technology, various new types of silicone rubber continue to emerge, such as high-strength, high tear, low compression deformation silicone rubber, as well as new varieties with strong specificity such as high temperature resistance, ultra-low temperature resistance, flame retardancy, and thermal conductivity. The emergence of these new varieties has further expanded the application fields of silicone rubber.
