What is NBR Rubber ?

  • Nitrile rubber sheeting (NBR) is a synthetic material that is used in a wide range of applications due to its resistance to most petroleum based fluids, oils and greases. Nitrile offers moderate mechanical properties and has satisfactory resistance to aromatic hydrocarbons, but is not suitable for use with ketones. If improved or specific material characteristics are required we offer BS 2751, blue food quality, white food quality and blue metal detectable nitrile grades that comply with British and American regulations.

    Nitrile rubber sheeting can be cut to suit your requirements utilising CNC machinery into gaskets, supplied by the roll, or manufactured into sleeves. It is also available to buy online at PAR Direct by clicking the link above.

    Nitrile rubber is also referred to as Buna-N, NBR rubber and Perbunan.

Structure of NBR Rubber

- NBR rubber structure is a copolymer of butadiene and acrylonitrile. NBR is produced by emulsion polymerization, the process of forming NBR rubber follows the following basic stages: Polymerize NBR in latex form, then coagulate and dry the latex. The Copolymerization process can be hot or cold polymerized to produce the final product.

- Normally, cold Copolymer products are softer and thinner than hot Copolymers. They are classified based on the acrylonitrile (ACN) ratio of the copolymer viscosity and the polymer chain

CẤU TẠO CAO SU NBR CHỊU XĂNG DẦU Cao su nitrile hay cao su NBR, tên gốc: nitrile-butadiene rubber, hay cao su tổng hợp chịu dầu, được sản xuất từ một chất đồng đẳng của acrylonitrile và butadien.
