✅ Main features of silicone gaskets:

1. Ultra-wide temperature resistance range

Silicone can maintain elasticity and sealing performance in the range of -60℃ to +200℃ or even +250℃, which is suitable for environments with frequent alternation of hot and cold, especially for high and low temperature alternation conditions (such as ovens, refrigerators, electric heating equipment, etc.).

2. Soft and elastic, stable sealing performance

Silicone gaskets have good flexibility and compression rebound ability, can fit uneven sealing surfaces, fill small gaps, and provide long-lasting and reliable static sealing effects.

3. Environmentally friendly and non-toxic, can be used for contact with food or human body

Medical grade and food grade silicone meet FDA, LFGB, ROHS and other safety standards, and are often used in food processing equipment, baby products, medical instruments and other fields.

4. Excellent insulation

Silicone is naturally an electrical insulating material with high dielectric strength and voltage resistance. It is suitable for insulating gaskets and sealing liners in various electrical equipment.

5. Strong weather resistance and aging resistance

Silicone has strong resistance to ozone, ultraviolet rays, oxidation, wind and rain. It is not easy to become brittle and aging when used outdoors, and is an ideal choice for outdoor equipment sealing.

6. Foamable and solid, strong adaptability

Silicone gaskets can be made into foam structures (soft) for dustproof, shockproof, and waterproof, or solid structures for medium-strength sealing occasions. The thickness and hardness can be customized.

❗ Limitations:

The mechanical strength and wear resistance are not as good as rubber such as NBR or EPDM, and it is not suitable for high-pressure or heavy-load sealing.

Not resistant to strong acids and alkalis and certain organic solvents (such as benzene, ketones, and esters). The chemical industry needs to pay attention to media compatibility when using it.
