1. Good sealing function, waterproof, environmental protection, non-toxic;

2. It can be heated under high-intensity temperature, without deformation and harmful substances;

3. Excellent tensile strength characteristics;

4. Long term use will not change the yellowing;

5. Corona discharge resistance, electrical isolation resistance, high and low temperature resistance test, good aging resistance and heat resistance;

6. Good temperature resistance, silicone rubber sealing ring can be used for a long time at 150 ° C without characteristic change, can be used continuously for 10000 hours at 200 ° C, and can also be used temporarily at 250 ° C;

7. Silicone sealing strip has good cold resistance. General plastic is generally - 20 ℃ - 30 ℃, while silicone rubber sealing ring still has good ductility at - 50 ℃ - 60 ℃. Some special low temperature resistant silicone materials can also bear lower temperatures.
