What are the performance and daily life application of silicone ring?

Silicone rings have a wide range of uses, and are mostly used in daily life for sealing appliances such as rice cooker lid rubber rings. Storage tank aprons, water cup aprons, etc. Silicone rings are used to make various seals. In fact, there is another kind of decoration on the hand that is also made of silicone ring, which is a very popular bracelet among young people. Whether it is a sports bracelet or a watch bracelet, the decorative bracelet for the team members to identify the team has its existence.

Due to the rubber ring in the rice cooker, the silicone ring has superior heat resistance, can withstand a high temperature of nearly 350°, and can be used almost forever at 150° without performance changes, and can be used continuously for 10,000 hours at 200°. Good electrical insulation properties (volume resistance greater than 10 ohm.cm, breakdown voltage above 30kv/mm), corona resistance and arc resistance. Low-temperature elasticity and particularly excellent resistance to oxidation and ozone, with high gas permeability and selectivity to gas permeation. Also used in thermos bottle sealing ring.

Due to the low surface energy of the silicone ring, it is hygroscopic and can play a role in isolation. Compatible with most oils, chemicals and solvents. Special silicone rubber also has properties such as radiation resistance, flame resistance and oil resistance. It is used in watch ring design instead of metal chain or plastic strap. The circular design of the hand fits better and is more convenient. Good sealing and water-proof performance can better protect the watch core from being affected by moisture. Therefore, many high-end electronic sports products are designed with silicone rings. Because silica gel is easy to color and bright in color, it is more likely to be loved by the younger generation, and it also meets the needs of high-end technology to adapt to the young people's pursuit of the fashion market.

But it has certain shortcomings in itself, such as water resistance, but poor resistance to water vapor, and it is not recommended to use it when the pressure exceeds 50psi. Generally, silicone rubber has good resistance to acids and alkalis, acceptable to polar solvents, and not resistant to alkane hydrogen and aromatic oils. It is not recommended to use in most concentrated solvents, oils, concentrated acids and diluted caustic soda solutions. It has low tensile strength and weak wear resistance, so it is generally not used for dynamic sealing.
