Nitrile Rubbrt

(NBR)

■Good oil and fuel resistance

■High tensile strength

■Low swelling in water

■Poor weather and ozine resistance

■Poor resistance against polar lkuids

■Poor resistance against clhydrocarbon

■Poor resistance against aromatic fluids

Fluorinated Rubber

(FKM)

■The resistance against oil and fuels is better than other types

■The only highly elastic rubber whice is resistance to aromatci and chlornated hydrocarbons

■Exccllcent hcat resistance

■Exccllcent weather and ozonc resistance

■Exccllcent acid resistance

■Low swelling in water

■Limited cold flexibliity

■Limited tensile and tear strength

■Limited wear resistance

■High compression set in hot water

■Poor resistance to polaric solvents

Polyacrylate Rubber

(ACM)

■Good oil and fuels resistance

■Good weater and ozone resistance

■Not usable in contact with water and water solutions

■Limited cold flexibility

■Limited tensile strength and tear resistance

■Poor wear reisistance

■Poor resistance against polar and aromatic and chlorinared hydrocarhons

Silicone Rubber

(VQM)

■Best heat resistance of all rubber types

■Excellent low temp resistance of all rubber types

■Excellent weather and ozone resistance

■Poor tensile and tear strength

■Poor wear resistance

■Sensitive to hydrolysis

■Poor resistance against aromatic oils and oxidized mineral oils

■Poor diffusion resistance
