Problems solved by technology

Silicone tube is a product made by mixing and extruding silicone rubber raw rubber and other additives. In the process of practical application, silicone tube is usually exposed to high temperature and high humidity environment. The existing silicone tube has high temperature resistance In addition, as a polymer material, its flame retardancy is not very ideal. In the process of use, it often has the defect of short service life.
