High Temperature Resistant EPDM Rubber Sponge Seal Strip For
Automotive
Density is a key parameter of EPDM foam, directly affecting its
compressibility, resilience, and sealing properties.
- Low-density EPDM foam (0.03-0.1 g/cm³): Typically used in
applications requiring lightweight materials, such as cushioning
and shock absorption pads in electronic devices. Due to its low
density, it offers good compressibility but relatively poor
resilience and durability, making it suitable for applications with
less stringent sealing requirements.
- Medium-density EPDM foam (0.1-0.3 g/cm³): Widely used in sealing
gaskets and waterproof gaskets in electronic devices.
Medium-density foam strikes a balance between compressibility and
resilience, providing excellent sealing while also offering a
certain degree of durability.
- High-density EPDM foam (0.3g/cm³ and above): Suitable for
applications requiring high sealing and durability, such as
electronic device housing sealing and waterproof joints.
High-density foam has excellent resilience and compressive
strength, ensuring long-term sealing.

FAQ:
Q1:Can rubber sheets be customized?
Yes! Rubber sheets can be cut, punched, or molded into specific
shapes, sizes, and thicknesses.
Q2:How do I maintain and clean rubber sheets?
Use mild soap and water; avoid harsh chemicals.
Store in a cool, dry place away from direct sunlight.
Q3:Are rubber sheets resistant to chemicals?
It depends on the material:
Nitrile (NBR) – Resistant to oils and fuels.
EPDM – Resistant to acids, alkalis, and polar solvents.
Neoprene(CR) – Good for mild chemicals and oils.
Q4:What is the temperature range for rubber sheets?
Standard Rubber: -40°C to +70°C
Silicone Rubber: -60°C to +230°C
EPDM: -50°C to +150°C
Q5:How long do rubber sheets last?
Lifespan depends on material, environment, and usage. Properly
maintained rubber sheets can last 5-15 years.
