Nipol NBR is produced in a variety of powder and crumb forms with mineral or PVC partitioning agent.

Nipol NBR liquids are copolymers of butadiene and acrylonitrile of medium acrylonitrile content. The outstanding characteristic is their liquid state, provided by very low molecular weight. Nipol NBR liquids can be used in blends with other Nipol polymers, imparting flow and knitting to molded goods, roll covering compounds and extrusions, while allowing the development of a compound which is essentially free of extractable or volatile components

Carboxylated Nipol NBR's are used in high-abrasion applications,such as rolls, conveyor belting, hose covers, oil well drilling parts, high modulus wear seals and premium footwear soles. Working with carboxylated Nipol NBR's requires special compounding considerations. Customary peroxide of sulfur cure systems common to conventional Nipol NBR react identically with the butadiene network in the carboxylated Nipol.
