Silicone foam long - term sealing durability and environmental performance

The long-term compression resistance of silica gel sealing material is an important factor affecting the durability of long-term sealing. Choosing materials with excellent compression resistance and permanent deformation performance helps to maintain consistent closing force on the door or panel, forming a more durable sealing effect. Compression permanent deformation resistance is to point to in certain time and temperature, elastomer in the compression load ability to restore to the original thickness after his release, if the gasket compression deformation is large, so the sealing effect may be affected by the gasket thickness reduction, this kind of thickness loss usually occur in use after a period of time, in the initial testing phase is not always obvious. Silicone foam has excellent anti-peristaltic deformation characteristics, showing excellent physical characteristics and sealing characteristics during the use of the product.

Silicone foam sealing

A successful silicone seal or gasket should be at the same time the oxygen resistance to chemicals and solvents, gas release, and temperature load, flame retardancy, and standard of sealing, the silicone foam has low outgassing rate and can't afford to fog characteristics such as environmental protection, there aren't any pollution equipment plasticizer or other chemicals, residual materials won't become fragile fragile, also have no corrosive to metal.
