Material | Temperature | Use Description | |||||||||||||||||
NBR | -23℃ ~ 82℃ | 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. | |||||||||||||||||
Shot time-23℃ ~120℃ | |||||||||||||||||||
EPDM | -20 ℃~130℃ | 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. | |||||||||||||||||
Shot time-30℃ ~ 150℃ | |||||||||||||||||||
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. | |||||||||||||||||
PTFE | -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. | |||||||||||||||||
