This blog post comes from CGR Products content series called “Material of the Month.” The series spotlights some of the unique materials that CGR works with, as well as common applications.

Material selection can make all the difference when bringing a simple design idea to life. From cross linked polyethylene (XLPE) to acrylic foam tapes, Material of the Month series highlights the benefits of these unique materials. 

What is EPDM Rubber?

Ethylene propylene diene monomer (EPDM) rubber, also known as synthetic rubber, is a smooth elastomer used in a wide variety of both specialty and general-purpose applications. It is resistant to heat, weather, and steam, and also functions as an excellent electrical insulator.

Benefits and Uses

Seals made from Ensolite Component Foam Material

EPDM rubber is exceptionally resistant to heat, oxidation, electricity, ozone, weather aging, and polar solvents such as alcohol, water, ketones, alkalines, and diluted acids. The water resistance and insulating qualities make EPDM rubber a popular choice for cable-jointing and other electrical applications.

EPDM rubber’s most frequent use is in seals for automotive vehicle windows, doors, and trunks, as well as cold-room doors, such as a refrigerator. The material’s strong insulating properties help to prevent water, heat, or cold from entering the sealed environment.

Other common uses of EPDM rubber include:

  • Automotive weather stripping
  • Tubing and hoses
  • Belts
  • Glass-run channels
  • Washers
