EPDM Elastomers

Rubber bushings EPDM for seal manufacturing

Color – black/BLUE EPDM Elastomers

EPDM | FDA is based on ethylene-propylene rubber and is commonly known as EPDM. It has outstanding resistance to hot water, steam (up to 180 °C), washing agents and polar organic solvents and good resistance to weathering, ozone and ageing. EPMD | FDA is not resistant to mineral, vegetable and animal oils, resistance to gas permeability and radiation is low.
EPDM | FDA can be used in glycol based break fluids, provided previous successful tests passed. EPDM | FDA corresponds to foodgrade standards.

EPDM can be used for production of U-shaped seals, lip and chevron seals. EPDM is mainly used in cleaning equipment (washing powder, sodium alkali). Moreover, EPDM is the most applicable material for usage in hot water or hot steam (silicone grease lubrication).

Mainly used

  • Special parts for cleaning equipment
  • Piston and rod seals
  • O-rings
  • Seals for vehicle break system

All above established data results from random tests which were taken from the functioning production. All data was stated based on standard test-products in accordance with ISO, DIN and ASTM standards and can substantially not be extended to the completed seal. Our practical technical recommendation, either oral, written or through tests is given in conformity with our best knowledge. However, this data is to be regarded as non-obligatory advice, also taking into consideration any protective rights of a third party, and does not acquit you from making tests with our product in relation to its adaptability for the assigned process and intendment. Utilization, application and processing of the products befall completely outside of our control and are therefore solely your liability. As regards the responsibility, it will be limited to all damages in the value of the product which we delivered and you applied. Certainly, we do assure the immaculate quality of our products in concordance with our general sales and delivery conditions.
