Characteristics and Application of EPDM Rubber Sponge


  EPDM rubber is a terpolymer of ethylene, propylene and non-conjugated diene. Diene has a special structure, with only one active double bond participating in the reaction during the copolymer reaction, and the remaining lower active double bond remaining on the molecular chain of the copolymer as an unsaturated point for sulfur vulcanization. The main chain of EPDM rubber is saturated, so it has characteristics of heat resistance, sunlight resistance and ozone resistance. The EPDM rubber is non-polar in nature, being resistant to polar solutions and chemicals, with low water absorption and good insulation properties. So, what are the characteristics and uses of EPDM rubber sponge? Then, the rubber sponge manufactures of Century Creation will briefly talk about it.

  Characteristics of EPDM rubber sponge:

  1. Light weight, good toughness and good tear strength

  2. A buffer material with a variety of elasticity

  3. Excellent weather resistance, oil resistance, weather resistance and solvent resistance. EPDM closed-hole foam products boast the following characteristics: good sealing, waterproof, shock absorption, independent foam structure, good flexibility and high resilience.

  The uses of EPDM rubber sponge:

  1. It can be used for industrial products, such as new energy vehicles, precision electronic products, OA, AV, communication equipment, home appliances, computer cases, as well as automobile industry, medical equipment, sports equipment and others.

  2. It can be used for civil and construction supplies, such as caulking materials for residential boards, sealing materials for residential doors and windows, concrete shrink-proof wood lining materials, materials for open channels and waterways, various civil engineering building materials, etc..

  3. It can be used for sealing materials of door, luggage, various pipeline and lamp, engine hood cushion, engine shock-proof materials, and instrument-type buffer and sealing materials, etc..
