|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℃|
|Cold-resistanting NBR:Offer less Oil-Resistance than Buna-NBR.|
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.

|-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.
