The self-explanation of the silicone ring is impressive!
Silicone products are common silicone products in our lives. In many cases, we need to use silicone products. It can be said that silicone products occupy most of our lives. Today, the editor is going to introduce silicone rights, which may be many. People will wonder, what is a silicone ring? Let me introduce it to you below.
Silicone ring is a kind of sealing ring. Silica gel is a kind of rubber material. Because of its special properties, wide temperature resistance range and excellent chemical properties, it is called special rubber together with fluorine rubber. Silicone is widely used to make various seals. The sealing ring is mainly used to seal the gas against oil, water and corrosion to prevent leakage.
Silicone rings are based on silicon obtained from quartz, and are saturated non-polar rubbers formed by silicon atoms attached to side chains such as methyl and vinyl. Different side chains result in different properties of silicone rubber. Methyl vinyl silicone rubber (VMQ) is one of the most widely used silicone rubber materials.
The performance of the silicone ring:
Heat resistance: Silicone rubber has much better heat resistance than ordinary rubber, can be used almost forever at 150° without change in performance, can be used continuously for 10,000 hours at 200°, and can also be used for a period of time at 350° . Widely used in occasions requiring heat resistance, thermos seal ring, pressure cooker ring heat-resistant handle.
Cold resistance: The delay time of ordinary rubber is -20°-30°, that is, silicone rubber still has good elasticity at -60°-70°, and some specially formulated silicone rubber can also withstand extremely low temperatures, such as: low temperature sealing ring.
The surface energy of the silicone ring is low, it is hygroscopic, and it can play a role in isolation. Water resistance, but poor water vapor resistance, not recommended for pressures above 50psi. Compatible with most oils, chemicals and solvents. Generally, silicone rubber has good acid and alkali resistance, acceptable resistance to polar solvents, but not alkane hydrogen and aromatic oils. It is not recommended to be used in most concentrated solvents, oils, concentrated acids and diluted caustic soda solutions. Special silicone rubber also has radiation resistance, flame resistance, oil resistance and other properties. It has low tensile strength and weak wear resistance, and is generally not used for dynamic seals.
