construction industry
Silica gel has good weather resistance and construction properties, and has been widely used as a bonding sealant in the construction industry, surpassing other types of sealants. In recent years, low-modulus and high-elongation two-component sealants have been developed, which are used for large-scale components such as precast concrete parts and curtain walls with large joint movement. Room temperature curing silicone is also used for the sealing of asbestos cement board joints, bathroom tile joints and toilet utensils. With the decline of rubber prices in the future, the scope of application will be further expanded, such as replacing asphalt and neoprene in the application of road joints. High temperature curing silicone sponge strips are used as sealing strips for doors and windows of buildings.

medical field
Silica gel has good biocompatibility, small reaction to the body, stable performance, low blood coagulation, can withstand high temperature and high pressure multiple cooking, and can be processed into various shapes of products, such as films, sponges, airbags, is the current medical One of the most widely used materials.

Other fields
In addition to the various applications mentioned above, the application of silica gel in the fields of textile, printing, machinery, plastics, chemistry, papermaking, and food and cosmetics has also increased significantly. Typical products are rollers made of silicone for heat setting of fabrics, plastics, embossing, calendering and fixing in copiers. Air-conditioning windows made of silicone membranes have been used to store fruits and vegetables. In addition, silica gel has also achieved good results in textile high-temperature equipment and equipment with high concentrations of alkali, sodium hypochlorite and hydrogen peroxide.
