EPDM Rubber strips Vip Rubber and PlasticEPDM molded compound products are known for their excellent resistance to ozone, mild acids, detergents, alkalis, silicone oils, alcohol and ketones. Due to its environmental resistance, this material is commonly used in the automotive, water (including hot and steam), HVAC and construction industries.

This material is more economical than silicone and is a copolymer of ethylene and propylene combined with adiene. It is highly chemical and ozone resistant.

Characteristics of EPDM

EPDM is ASTM D-2000 classification CA and is known by its chemical name Ethylene Propylene Diene Monomer.

  • Heat Aging Resistance – Excellent
  • Abrasion Resistance – Good
  • Compression Set – Good
  • Tear Resistance – Fair
  • Weather Resistance – Excellent
  • Ozone Resistance – Excellent
  • Gas Permeability Resistance – Poor
  • Oil Resistance – Poor
  • Standard Temperature Range: -20° to +350°F
  • Hardness (Shore A): 30 to 90

Common Uses for EPDM

EPDM is an extremely versatile material that can be used in a wide variety of products that include:

  • Seals
  • Gaskets
  • Aircraft Tubing
  • Window Seals
  • Weather Stripping
  • Setting Blocks

Industries Using EPDM

With its excellent resistance to weather and heat and good flexibility in low temperatures, custom EPDM rubber parts are used in Aircraft as window seals and tubing and within military and defense as seals, gaskets, tubing, and sheet. It is also used extensively in architecture as a window seal and as setting blocks as well as in electrical as connector seals, covers, and washers. Its environmental resistance also makes it a go-to material for HVAC, medical, marine, and many other industries.
