Seals are now widely used in various fields. In the industrial field, they are mainly used in industries that require seals such as hydraulic pressure and pump valves. This article mainly describes the characteristics and use of nitrile rubber seals. Please look down.
Nitrile rubber (NBR English name: Nitrile-ButadieneRubber)
Nitrile rubber polymerization monomer for butadiene and acrylonitrile, is a polar rubber
The main performance characteristics:
Advantages:(1) because it contains polar AN groups, it has high stability to non-polar or weak polar animal and vegetable oils, liquid fuels and solvents, and the higher the AN content, the better the oil resistance.
(2) heat resistance is better than NR, SBR, CR
(3) good air tightness second only to butyl rubber
(4) Poor cold resistance, the higher the AN content, the worse
(5) is a non-crystalline rubber, need carbon black reinforcement
Disadvantages: poor insulation, small volume resistance
Application areas: used in the manufacture of oil-contacting rubber hoses, rubber curtains, gaskets, shop tank linings, aircraft fuel tank linings, large oil bladders, conveyor belts and bearings and other oil-resistant rubber products; various materials are used in different areas, I hope to be useful to you.
