Product Details
Nitrile Butadiene Rubber (NBR70) O-Ring oil resistance hydraulic seal
Nitrile butadiene rubber or nitrile rubber is copolymerized by acrylonitrile and butadiene with acrylonitrile content ranging from 18% to 50%. Nbr is one of the most commonly used rubbers for oil seals and O-rings.
With the containing of acrylonitrile, the higher the acrylonitrile
content, the better the resistance to petrochemical hydrocarbon
fuel. However, the performance under low temperature will be
poorer. The normal temperature range for product use is from -25 °C
to 100 °C.
Used for fuel tanks, lubricant oil tanks, and to make rubber parts
used in fluid media such as petroleum hydraulic oil, gasoline,
water, silicone grease, silicone oil, diester lubricating oil, and
glycol hydraulic oil. It is the most widely used and cost-effective
rubber seal in the market.
