NBR Rubber Features:
| Material | NBR(Nitrile Rubber/Buna-N) |
| Advantage | 1,Excellent Abrasion-Resistance,Good Rebound Resistance |
| 2,Good Tensile Strength and Elongation |
| 3,Excellent Animal and Vegetable Oil Resistance |
| 4,Good Oil and Fuel Resistance |
| 5,Good Water Resistance |
| Disadvantage | 1,Poor Oxygenated-Solvent Resistance |
| 2,Poor Ozone Resistance |
| Temperature | -40℃-120℃, -50℃-150℃(special formula) |
| Application | 1,Fuel tank, lubricating oil tank and oil in the hydraulic oil,
gas, water, silicone grease, silicone oil and other fluid medium
rubber parts, especially the sealing parts. |
| 2,It is currently the most widely used, the lowest cost of rubber
seals. |
Nitrile rubber (NBR, Buna-N) provides excellent resistance to
petroleum oils as well as mineral and
vegetable oil. Nitrile rubber also offers strong resistance to heat
aging - often a key advantage over
natural rubber.
Nitrile rubber performs well in carburetor and fuel pump
diaphragms, aircraft hoses, seals and gaskets
as well as oil-lined tubing. Due to its versatility, nitrile is
used in applications involving not only oil and
fuel resistance, but those applications requiring resistance to
heat, abrasion, water, and gas permeability.
