Silicone seals are seals, which is made of all kinds of silicone. It usually is made with the shape of an annular, so that it can fit the sealing of gaskets or ferrules. Nowadays, silicone seals are popularly used for the waterproof sealing and preservation of dairy products, such as crisper boxes, rice cookers, water dispensers, lunch boxes, heat preservation boxes, crisper boxes, water cups, ovens, magnetized cups, coffee pots, etc. It is easy to use, safe and has environmental protection.

Silicone is a kind of highly active adsorption material and an amorphous substance. Its chemical molecular formula is mSiO2·nH2O. And insoluble in water and any solvent, non-toxic tasteless, and stable chemical properties. In addition to strong alkali, and hydrofluoric acid, silicone does not react with any substance. Because of its special performance, wide temperature resistance range, and excellent chemical performance, therefore, silicone is also widely used in the production of various seals to meet our mechanical production and life in a variety of sealing requirements.

I. Wide temperature resistance range
Silicone can be placed under high-temperature heating without deformation and harmful substances. It can work under 150℃almost forever without performance changes, and also can continuously be used under 200℃ for 10000 hours, so it is widely used in the requirements of heat resistance, such as hot water bottle sealing rings. Under -60℃ ~ -70℃, silicone still has good elasticity. Even some special silicone rubber can withstand lower temperatures, such as low-temperature silicone seals.
II. Good insulation perfor
