The development of silicone rubber began in the 1940s, with the earliest production by companies such as Dow Corning and General Electric in the United States. China successfully researched and industrialized silicone rubber production in the early 1960s. Currently, countries producing silicone rubber include China, the United States, the United Kingdom, Japan, the former Soviet Union, and Germany, with over 1,000 varieties and grades available.
Silicone rubber can be classified into three main types based on its vulcanization mechanism: heat-vulcanized, room-temperature-vulcanized, and addition-reaction-type. Among them, heat-vulcanized silicone rubber is the earliest type of application and has many varieties, such as polydimethylsiloxane rubber and methylvinylpolysiloxane rubber. These different types of silicone rubber have various properties suitable for different application fields.
With technological advancements and increasing demands for material performance, the properties of silicone rubber are continuously being improved and refined. In the future, silicone rubber is expected to find applications in more fields, such as biomedicine and aerospace. At the same time, environmental protection and sustainable development will also become important directions for the development of silicone rubber, driving the silicone rubber industry towards a greener and more environmentally friendly direction.
