There are many advantages of silicone sealing rings.   1. Excellent weather resistance The Si-O-Si bond in silicone rubber is very stable to oxygen, ozone and ultraviolet rays, and has excellent resistance to ozone and oxide erosion. Without adding any additives, it has excellent weather resistance, and it will not crack even if it is used outdoors for a long time. It is generally believed that silicone rubber seals can be used outdoors for more than 20 years.   2. The material is safe and environmentally friendly Silicone rubber has its unique physiological inertness, non-toxic, tasteless, odorless, good preservation effect, and less interference from the external environment, long-term use does not yellow, does not fade. And in line with the national food and medicine health standards, mostly used in food, medicine, aluminum silver paste and various oils filtration and impurity removal.   3. Good electrical insulation performance Silicone gel has excellent electrical insulation properties, corona resistance and arc resistance.   4. High air permeability and selectivity for gas transmission Due to the molecular structure of silica gel, the silicone sealing ring has good air permeability and good selectivity for gas, and the air permeability of silicone rubber to air, nitrogen, oxygen, carbon dioxide and other gases at room temperature is 30-50 times higher than that of natural rubber.   5. It has hygroscopic performance The surface energy of the silicone ring is low, which has the function of absorbing moisture in the environment and plays an insulating role.   6. Wide range of high and low temperature resistance High temperature resistance: The silicone sealing ring can be heated at high strength temperature without deformation and does not produce harmful substances. It can be used almost forever under 150 without performance change, can be used continuously for 10,000 hours under 200, and can be used for a period of time under 350. Widely used in applications requiring heat resistance, such as: hot water bottle seals. Low temperature resistance: silicone rubber still has good elasticity at -60~-70, and some specially formulated silicone rubber can also withstand more demanding extremely low temperatures, such as: low-temperature sealing rings, the lowest can reach -100.

What is Silicone sealing rings? Silicone sealing ring is a ring with silicone rubber as raw material, composed of one or several circle-shaped silicone rubber materials, fixed on the bearing of the machinery to play a non-slip, tight and sealing role. It is a kind of sealing ring, because of its special performance, wide temperature range, excellent chemical properties, widely used in the production of various seals.    Classification and use of silicone sealing rings Silicone sealing rings can be divided into O-type silicone rings, V-shaped silicone rings, square silicone rings, special-shaped silicone rings, etc. Its main function is waterproof sealing and preservation, not only suitable for household appliances such as electric water heaters, electric irons, microwave ovens, etc., but also suitable for a variety of products that have contact with the human body, such as kettles, water dispensers, lunch boxes, rice cookers, etc.
