EPDM rubber is an extremely durable and flexible synthetic rubber. Therefore, it is used in a wide variety of applications, including the automotive sector (where it is used for EPDM seals in windows and doors, as well as cooling system hoses), refrigeration cells, and non-slip coatings for bridges and children’s playgrounds.

EPDM ethylene propylene is a copolymer with elastomeric properties, which means that it is extremely elastic. If stretched, it will return to its original shape. Its two main components (ethylene and propylene) are derived from crude oil and natural gas.

EPDM rubber: composition and additional properties

EPDM rubber compounds have different properties that change depending on the rubber used, even though the characteristics are generally very similar.

In particular, the difference becomes evident regarding heat resistance where, with the use of peroxic cross-linked EPDM, seal resistance increases up to about 150°C, while with the use of peroxide vulcanized EPDM compounds, resistance increases up to about 200°C.

In addition, EPDM rubber is particularly resistant to:

  • Impact
  • Elongation
  • Low temperatures
  • Chemical agents

Due to all these remarkable properties, the EPDM rubber compound is used particularly in the automotive industry to manufacture basket profiles, bumpers, and hoses. It is also used for gaskets in household appliances and for covering electrical cables.

Lopigom uses EPDM compounds to manufacture different seals and other components for applications in multiple sectors.
