Information about material
Nitrile rubber (NBR):MaxTemperature 100 Celsius,good resistance to oil
Silicone rubber:(VMQ):MaxTemperature 200 Celsius,common oil resistant ,non-toxic good waterproof,
Viton:Tmax 280,good oil-resistant,wear – resistant corrosion – resistant
EPDM:Tmax 150,Good Oxidation resistance, ozone resistant and anti erosion,Common oil resistant.
polytetrafluoroethylene(PTFE):Tmax 280,non-stick very non-reactive Acid alkali resistance, resistance to organic solvents extremely low coefficient of friction.
Advantage:
NBR has good resistance to mineral oils, vegetable oils, benzene/petrol, ordinary diluted acids and alkalines.
Weak point:
Not suit for polar solvent,ex.ketone,Ozone,nitro-hydrocarbon,MEK,chloroform
