What is NBR?
 
Nitrile rubber, also known as nitrile butadiene rubber, NBR, Buna-N, and acrylonitrile butadiene rubber, is a synthetic rubber derived from acrylonitrile (ACN) and butadiene.
 
Use of NBR
 
Used in the automotive and aeronautical industry to make fuel and oil handling hoses, seals, grommets, and self-sealing fuel tanks.
 
Used in the nuclear industry to make protective gloves.  
 
Used to produce molded goods, footwear, adhesives, sealants, sponges, expanded foams, and floor mats.
 
Its resilience makes NBR a useful material for disposable lab, cleaning, and examination gloves. 
 
Advantages of NBR
 
Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but has inferior flexibility. 
 
Nitrile rubber is less likely to cause an allergic reaction than natural rubber.
