EPDM silicone gasket

The EPDM silicone sealing ring is a composite sealing component that combines the weather resistance of EPDM with the elasticity of silicone. Its core advantage lies in adapting to harsh environments across multiple scenarios while maintaining long-term sealing performance.

1. Core Performance Features

1. Excellent weather and aging resistance: It can withstand a wide temperature range from -40°C to 150°C, with slow performance degradation when exposed to sunlight, ozone, and rain, making it suitable for outdoor equipment.

2. Excellent chemical stability: It exhibits good resistance to water, steam, weak acids and alkalis (such as ordinary tap water and diluted acid/alkali solutions), as well as most industrial lubricating oils, with minimal swelling or corrosion.

3. Sealing and Elastic Balance: Retains the high elasticity and low compression set characteristics of silicone, while enhancing wear resistance through EPDM. In dynamic or static sealing scenarios, it ensures continuous contact with the sealing surface, minimizing leakage risks.

II. Applicable Application Scenarios •

Automotive sector: Used for sealing door and sunroof strips, as well as the engine cooling system and air conditioning pipelines. It resists high engine temperatures and external climatic effects.

• Home Appliances and Bathrooms: Water inlet valves for washing machines, sealing rings for water heaters, sealing components for bathroom faucets and showerheads, capable of withstanding hot water and humid environments.

• Industrial Equipment: Static sealing for valves and pump bodies, waterproof sealing for electronic equipment enclosures, suitable for low-pressure and non-strong corrosive industrial conditions.

3. Common Specifications and Customization

• Standard Forms: O-rings, flat washers, and special-shaped sealing rings (e.g., customized structures with raised or recessed features).

• Size Range: The inner diameter can range from a few millimeters to several tens of centimeters, with a cross-sectional diameter typically between 1mm and 20mm. Customization is available based on customer drawings or samples.  • Color Options: Standard options include black and transparent, with the ability to customize specific colors such as red or blue without affecting core performance.
