EPDM is a copolymer of propylene and ethylene, amalgamated with a terpolymer of propylene, ethylene, and diolefin to allow sulfur vulcanization.
Salient Features:
Good elasticity
Weather-resistant
Aging, heat and cold resistant
Chemical resistant
Low compression set
Steam and hot water-resistant
Common Applications:
Solar panel heat collectors
Weather-resistant uses
Electrical insulation
Automotive seals
Automotive brake and cooling systems
Garden appliance such as hose, tubing, washers, belts
Properties:
Hardness: 30-90 Shore A
Temperature resistance: -40° C to + 130° C
Standard colors: Black
Advantages:
EPDM performs exceptionally well in ketones, steam (up to 204°C), alkalis, alcohol, automotive brake fluid, silicone greases, and oils, dilute alkalis, phosphate ester-based hydraulic fluids, weathering, and ozone.
Limitations:
EPDM compounds are prone to halogenated solvents, hydrocarbon fluids, aromatic and aliphatic hydrocarbons, petroleum-based greases and oils, and di-ester-based lubricants.
