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℃
