Description
NBR is a copolymer of acrylonitrile and butadiene, offering excellent oil resistance, particularly tomineral oils, fuels, and lubricants. It is resistant to abrasion and water, but not to polar solvents(e.g., ketones, ozone). By adjusting the acrylonitrile content, a balance between oil resistanceand low-temperature performance can be achieved. WINBEST offers custom formulations tomeet different oil resistance grade requirements.
Applications
Fuel system O-rings
Hydraulic oil seals
Oilfield blowout preventer (BOP) seals
Industrial rubber rollers
