What is the difference between nitrile and Buna-N?

Nitrile rubber — also known as acrylonitrile butadiene rubber, NBR, or Buna-N — is a synthetically produced, petroleum-based rubber ideal for seals, gaskets and o-rings. Nitrile is a highly versatile rubber. It is used in countless applications and products, from marine fuel systems to small engine carburetors.

What does N stand for Buna?

BUNA-S. (1) Monomers 1,3-butadiene and acrylonitrile. (2) Also called as Nitrile-Butadiene-Rubber (NRB). (3) It is formed by polymerization of 1,3-butadiene and acrylonitrile in the presence of sodium.

What is Buna-N rubber used for?

Buna-N, also known as Nitrile, is the sealing industry’s most economical and widely used elastomer. This synthetic rubber material is ideally used for o-rings, gaskets, seals and custom molded components for a variety of industries and applications. Material selection plays a critical role in successful seal design.
