2. What is the function of silicone o ring?

1) Good compression deformation rate and rebound rate, which can avoid leakage caused by deformation during use.

2) Excellent sealing performance and is waterproof and leak-proof.

3) Good fresh-keeping effect, completely non-toxic and tasteless.

4) It can be heated at high temperature without deformation and no harmful substances are produced.

5) Good tensile performance, after special inspection and testing.

6) Corona resistance, arc resistance, high and low temperature resistance, good aging resistance, high temperature resistance, in line with FDA and SGS standards.

7) Good elasticity and flex resistance: Silicone rubber is a kind of rubber, which has good softness and elasticity, and the number of bending times can reach hundreds of thousands, or even hundreds of thousands of times;

8) Salt spray resistance, good water repellency;

9) Excellent insulation performance: volume resistance can reach 1016Ωcm, breakdown strength ≧20-22KV/mm;

10) Good anti-ultraviolet, ozone and aging resistance;

11) Anti-pollution flashover, anti-leakage tracking, good creepage resistance, good self-cleaning property;

12) Dustproof. Silicone sealing ring has extremely high-quality sealing performance, and can achieve dust-proof effect during the sealing stage, such as rice cookers, water dispensers, etc. may use dust-proof effect!

13) High elasticity. It has better elasticity than ordinary rubber, and can maintain better elasticity even at minus sixty or seventy degrees.

14) Anti-tearing. It has excellent tensile performance, and can achieve the effect of not breaking or deforming under very strong pulling force.

3. What is the working principle of the silicone o ring?

The working principle of the silicone o ring: Silicone is soft rubber with resilience, and a silicone sealing ring is placed between two items to achieve an interference fit sealing state.


4. What are the uses of silicone o ring?

Silicone o rings are mainly used for waterproof sealing and preservation of daily necessities such as fresh-keeping boxes, rice cookers, water dispensers, lunch boxes, heat preservation boxes, heat preservation boxes, water cups, ovens, magnetized cups, coffee pots, etc. Fixed sealing, waterproof sealing, isolation sealing, heat preservation, pressure keeping, gas isolation and so on.
