Because of its resistance to most petroleum-based fluids, oils, and greases, nitrile rubber sheeting (NBR) is used in many applications. Nitrile has intermediate mechanical qualities and is resistant to aromatic hydrocarbons. However, it cannot use with ketones. We offer BS 2751, blue food quality, white food quality, and blue metal detecting nitrile grades that meet British and American laws if better or specialised material qualities are required.Nitrile rubber sheets can be cut to size using CNC machinery into gaskets, supplied in rolls, or made into sleeves.
