Nitrile butadiene rubber (NBR) of butadiene and acrylonitrile copolymer.

Characterized by resistance to gasoline and oils of aliphatic hydrocarbons are particularly good performance, after polysulfide rubber, acrylic rubber and fluorine, and superior to other general rubber.

Good heat resistance, air tightness, wear resistance and water resistance etc. good, strong bond. Suitable for petroleum-based hydraulic oil, glycol-based hydraulic oil, diester Department of lubricating oil, gasoline, water, silicone grease, silicone and other media use. It is currently the most widely used and lowest cost rubber seals.

The disadvantage is the poor cold resistance and ozone resistance, strength and low elasticity, poor acid resistance, good electrical insulation properties, resistance to polar solvent resistance is also poor. Does not apply to polar solvents being, such as ketones, ozone, nitro hydrocarbons, MEK and chloroform.

Operating temperature range: about -40 ~ 120 ?.

Color Black, specifications according to customer drawings or samples, also targeted exclusive design.

Permeability - Many sealing materials (materials) are porous, and after special treatment unless otherwise will be gas and liquid penetration. It is a measure of both direct potential leaks by sealing material (material) in.

Friction properties - have a good wear resistance, keeping the liquid membrane good wetting and good boundary lubrication properties.

pu value - it is sealing the sealing material (material) relative performance fit. May represent the product can withstand contact pressure and friction velocity to live. Sealing fluid nature of its impact is large, especially in increasing the value of silicon carbide pu love alkanes impact.
