Doking Material Performance
MATERIAL | TEMP | ADANTAGES | LIMITATION |
Nitrile Rubbrt (NBR) | -40~125ºC | 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) | -20~250ºC | 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) | -25~150ºC | 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) | -60~225ºC | 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 |
