Description
CR rubber features ether bonds and chloromethyl groups in its main chain, offeringexcellent resistance to oil, fuel, ozone, and weather, with very low permeability. It is alsonitrosamine-free, making it an ideal material for automotive fuel evaporation emission systems and environmentally friendly refrigerant seals.
Applications
Automotive fuel vapor hoses
Seals
Pneumatic control diaphragms
Printing rubber rollers

Advantage
Ozone and weather resistance far superior to NBR - suitable for outdoor or non-sheltered environments.
Very low permeability - ideal for air conditioning hoses and fuel evaporation control systems.
Excellent resistance to alcohol-containing fuels (e.g., methanol, ethanol).
Good dynamic sealing performance with low compression set.
