EPDM
EPM – EPDM or Ethylene – Propylene Rubber. EPM can only be vulcanised by peroxides or radiation; whereas EPDM can be vulcanised conventionally using sulphur.
-
Excellent inherent high and low temperature ranges. Typically -45º C to +120º C for standard compounds.
-
Special compoundig can increase some grades to function continually at +140 º C.
-
E.P's are inherently resistant to attack by oxygen, U.V., Ozone and extreme weather environments, and will give long service in these contidions.
-
E.P's do not have good adhesion properties and expert advice should be sought from our Technical Department about bounding applications.
-
Resistance to Chemicals; resistant to many chermicals and solvents. Good resistance to many corrosive chemicals. The performance of E.P's in hot water and high pressure steam is better than in dry heat.
