Product Description
Acrylonitrile-butadiene rubber (NBR)

Properties

Perbunan® is roa fast curing NBR rubber. Vulcanizates are characterised by a high modulus and good sealing force retention when correctly formulated and processed. Perbunan® grades are available in the range of 18 % to 45 % acrylonitrile content (ACN). Perbunan® is used for oil resistant rubber articles in general. They are especially suitable for mineral oil based hydraulic fluids, natural fats and oils. Vulcanizates based on high ACN grades are also used for fuel-related applications. Rubber articles based on Perbunan® are suitable for extreme low temperature flexibility (low ACN content) and in general for heat resistance up to 120 °C depending on the time of exposure. Further properties are good abrasion and wear resistance, low gas permeability and good physical properties. Perbunan® CHM grades are especially designed for molding applications to reduce the tendency of mold fouling tremendously.

Applications

Perbunan® is preferably used for molded rubber parts such as seals (including rubber-to-metal composites), membranes, vibration dampers and hoses. They are also used for rubberized fabrics (printing blankets, flexible containers), roll covers, sheets, conveyor and transmission belting, shoe soles, other footwear rubber parts, thermoinsulation articles and other applications.
If Perbunan® is fluxed with PVC, the blends are base polymers for colored ozone resistant articles such as hose covers, cable sheathing and spinning aprons.
