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.
