EPDM (Ethylene Propylene Diene Monomer)

Good resistance to most water based chemicals, very inert structure, remains stable over long periods of time, can withstand temperatures of up to 130°C for extended periods of time (months), very good weathering resistance, easily compounded and processed, outstanding resistance to phosphate ester type hydraulic fluids.

Performs well in Alcohols, automotive brake fluids, dilute acids and dilute alkalis, Ketones (MEK, acetone), Silicone oils and greases, Steam (up to 400° F, 204° C).

Attacked by oil or oil based products, aliphatic and aromatic hydrocarbons, Di-ester based lubricants, halogenated solvents. Compression set not as good as some other rubbers, but can be improved by compounding.

  • General Temperature Range: -65° to +300° F
  • Hardness Range 30 – 90 Shore A
  • Tensile 1000 psi .5 – 3.5
  • Elongation max 700 %
  • Compression Set moderate, can be compounded to requirements
  • Max Service Temp 275 ºF
  • Weathering outstanding
  • Service in Water excellent
