The characteristics and materials of rubber sealing rings -1. Elasticity and stretchability: Rubber sealing rings have excellent elasticity and stretchability, which can maintain shape under pressure and adapt to various sizes of interfaces. This characteristic enables it to achieve good sealing effects in various shapes and sizes of equipment. 2. Sealing performance: The rubber sealing ring has excellent sealing performance, which can effectively prevent the leakage of liquids and gases. In high-pressure, vacuum or humid environments, rubber sealing rings can still maintain their stability, ensuring the normal operation of equipment and systems. 3. Chemical corrosion resistance: Many industrial processes involve corrosive substances, and rubber sealing rings have good chemical corrosion resistance performance. This enables it to work stably for a long time in corrosive environments such as acid and alkali. 4. High temperature and low temperature resistance: High temperature and low temperature environments have high requirements for sealing materials. Rubber sealing rings are not easy to soften at high temperatures and not easy to harden at low temperatures, so they can maintain good sealing performance under extreme temperature conditions. 5. Anti aging: the rubber seal ring has good anti-aging performance, and can maintain its original elasticity and sealing performance even after long use. This ensures that it maintains good performance throughout long-term use.
