Material | Temperature | Use Description |
NBR | -23℃ ~ 82℃
Shot time-23℃ ~120℃ |
Buna-NBR:(Nitrile Butadiene Rubber ) has good tensile strength and resistance to abrasion.It is also resistant to hydrocarbon products.It is a good general-service material for use in
water,vacuum,acid,salts,alkalines,fats,oils,greases,hydraulic oils and ethylene glycol. Buna-N can not use for acetone,ketones and nitrated or chlorinated hydrocarbons. |
Cold-resisting NBR | -40℃ ~ 100℃
Shot time-45℃ |
Cold-resistanting NBR:Offer less Oil-Resistance than Buna-NBR. |
EPDM | -20 ℃~130℃
Shot time-30℃ ~ 150℃ |
General EPDM rubber: is a good general-service synthetic rubber used in hot-water, drinks, milk product systems and those containing ketones, alcohol, nitric ether esters and glycerol. But EPDM can not use for hydrocarbon based oils, minerals or solvents. |
Acid and alkali-resistanting EPDM | EPDM | Acid-alkali resistanting EPDM: offer Acid-alkali resistant better than General EPDM. |
Neoprene | -35℃ ~ 100℃
Shot time-35℃ ~ 113℃ |
Neoprene is recommended for moderate
acids,oils,fats,greases and solvents. It has good resistance to anhydrous ammonia and alcohlo |
Viton | -10 ℃~ 180℃ | Viton is a fluorinated hydrocarbon elastomer with excellent resistance to most hydrocarbon oils and gases and other petroleum-based products. Viton can not use for steam service, hot water over 82℃ or concentrated alkalines. |
Steamproof viton | 5 ℃~ 190℃ | Steam-resistant Viton has good Steam-resistance property and can offer Acid-alkali resistant better than Viton. |
Silicon | -40℃~180℃ | Silicone Rubber has good resistance to high
temperature and low temperature and its chemical is stable. It is recommended for foods,strong acids and weak alkalis. |
PTFE
(Inner liner EDPM) |
-5℃ ~ 110℃ | PTFE has good chemical performance stability and surface will be not sticky.
At the same time, it has good lubricity property and aging resistance. It is a good material for use in acids, alkalis, oxidant and other corrodents. |
PTFE
(Inner liner NBR) |
-5℃~90℃ |
