Information about material
NBR rubber solvent Media compatibility
Suitable media:
Fatty hydrocarbon (tetrane propane) engine oil ,motor oil , Fuel,Plant Oil,mineral oil.
HFA HFB HFC hydraulic oil.
Acid/alkali/salt solution of Normal temperature and low concentration .
Water
Ethylene glycol based brake fluid
Not suitable Media:
Fuels with high content of aromatic.
Romatic hydrocarbons (benzene)
Chlorinated hydrocarbons (trichloroethane)
Polar solvents (ketones, acetone, ethyl acetate, ethyl ether)
Strong acids
Advantage:
Good oil resistance, water resistance, solvent resistance.
Good pressure resistance, wear resistance and tensile strength
Using for rubber parts of fuel tank, oil tank.
Petroleum hydraulic fluids, gasoline, water, grease, silicone oil, diester lubricants, glycol systems.
Hydraulic oil and other fluid using rubber parts.
Shortage:
Not suitable for polar solvents, such as ketones hydrocarbons, ozone, Nitro, MEK and chloroform.
Not well ozone resistance, weather resistance, not hot air aging
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
Application:
Fuel container , lube oil container,Hydraulic oil of oil ,silicone lube,water,
diester lube sealing.It’s widely used and lower cost for oil.
