Material Notes:

Nitrile Butadiene Rubber (NBR), 65-75 °IRHD. High acrylonitrile (ACN) content. Copolymer of acrylonitrile and butadiene.Applications: The high acrylonitrile content of this rubber increases resistance to heat plus petroleum based oils and fuels, but decreases low temperature flexibility. Good water resistance but poor against ozone and weather.
