Silicone rubber has good weather resistance and workability. As an adhesive sealant, it has been widely used in the construction industry, surpassing other types of sealants. In recent years, a low-modulus high-elongation two-component sealant has also been developed, which is used for large-scale components such as concrete prefabricated parts with large joint movements and curtain walls. Room temperature vulcanized silicone rubber is also used for sealing joints of asbestos cement boards, sealing of bathroom tile joints and toilet appliances. With the decline of rubber prices in the future, the scope of applications will be further expanded, such as replacing asphalt and neoprene in the application of highway joints. High-temperature vulcanized silicone rubber sponge strips are used as sealing strips for doors and windows of buildings.
