Synthetic

Nitrile(NBR) Rubber

With Excellent resistance to oils, solvents and fuels. Resistant to a broader range of aromatic hydrocarbons than neoprene. Nitrile may be blended with SBR rubber to achieve an economically priced sheet or moderately oil resistant applications. Temperature range: -30℃ to +120℃, with the possibility of reaching -40℃.
