Buna-N Rubber Gaskets

Buna-N Rubber (also known as NBR – Nitrile Butadiene Rubber) is a material made for oil resistance. Buna-N Rubber displays excellent resistance to petroleum-based oils, fuels, water, alcohols, silicone greases and hydraulic fluids. It also has a good balance of desirable working properties like low compression set, high abrasion resistance and high tensile strength. The more nitrile there is within the polymer, the higher its resistance to oils but the lower its flexibility. Nitrile rubber is more resistant than natural rubber to oils and acids, and has superior strength, but suffers from inferior flexibility.

Nitrile Rubber’s Heat-Aging Advantage

Unlike natural rubber and other materials, nitrile rubber is more resistant to heat aging. This feature is a key advantage, as it allows nitrile to not harden and lose its damping capability as quickly as natural rubber and other solutions. Nitrile rubber is also a great material choice for applications that require abrasion resistance and metal adhesion.

Due to its versatility and strong resistances, nitrile material is used in applications involving not only oil, fuel, and chemical resistance, but also those that require resistance to heat, abrasion, water and gas permeability.
