Nitrile rubber (NBR, Buna-N) is a copolymerized synthetic rubber of Acrylonitrile and Butadiene.
ABOUT NBR
This type of synthetic rubber is used in applications requiring resistance to oil, fuel, greases and other chemicals. The higher the % of ACN within the polymer the more polar; thus, better resistance to oils. However, the higher the ACN %, the higher the glass transition temperature. The impact of ACN % on oil resistance and low temperature properties must be considered.
Grades available include standard NBR to low mold fouling grades, with a variety of mooney values from very high to very low. Also, we offer clean, carboxylated, Nitrile/PVC and powder grades. The advantage of the CLEAN line over traditional nitrile rubber is its reduced mould fouling, allowing for more injection cycles with less stops for mold maintenance. It helps the processability in transfer and injection molding. Carboxylated nitrile rubber improves traction, abrasion, tear, and modulus resistance.
