Nitrile Rubber Seal Has Good Water Resistance

May 18, 2017

One of the main features of nitrile rubber seal is oil resistance. Coupled with its physical and mechanical properties. NBR Oil SealSo it is used in the manufacture of various oil-resistant plastic products, nitrile rubber seal also has good water resistance, air tightness and excellent bonding performance. But its shortcomings are poor resistance to low temperature, poor ozone resistance, poor electrical properties, slightly lower elasticity.

Nitrile rubber oil seal material we are no stranger, also known as nitrile rubber oil seal oil seal. Its self-lubricating performance. Can be used for oil-free seal.

Nitrile rubber oil seal material is mainly used for static sealing and reciprocating motion seal. For rotary motion seals, limited to low speed rotary seal.

Nitrile rubber seal O-ring is generally installed in the outer or inner circle on the rectangular cross-section of the seal from the role. In the oil, acid, grinding, NBR Oil Seal chemical erosion and other environments still play a good seal, shock absorption. Therefore, the nitrile rubber seal is a very large number of seals used in hydraulic and pneumatic transmission systems.

Nitrile rubber oil seal is a highly saturated elastomer obtained by special hydrotreating of NBR.

Second, nitrile rubber seal What are the characteristics of it? The oil seal produced with hydrogenated butyl rubber is a new type of elastomer with excellent properties. Is the milk poly-Dingqing solution in the catalytic and high pressure, such as hydrogen and made, Dingqing rubber molecular chain due to hydrogenation from the unsaturated structure into a high saturation structure, similar to ordinary NBR, can fill more The sealing rubber prepared by blending with the hydrocarbon rubber has good cold resistance, resistance to resistance and compression and permanent deformation. Since the HNBR development time is short, it is resistant to its bonding with fiber and metal But also to develop the research stage.

 Third, the hydrogenated Dingqing rubber made of oil seals are generally applied to what industry sector? Hydrogenated Dingqing rubber developed oil seal has been widely used in automotive oil seal, oil field oil seal, for high hydrogen sulfide oil field, the application of hydrogenated Dingqing rubber to develop oil seal. Because of its cold resistance, excellent heat resistance can be used for gaskets, gaskets, O-ring and other fields; due to its resistance to chemical resistance, HNBR suitable for gas and anti-riot, NBR Oil Seal drilling shield, plunger, Sealing ring; because of its heat resistance, radiation resistance than silicone rubber, fluorine rubber, PTFE, and more suitable for the Department of various electrical rubber seal. HNBR due to low rigidity, process performance, low density can add more filler. Its product unit volume is only half of the fluorine rubber, and the price is much lower than the fluorine rubber, so it will become a substitute for the characteristics of fluorosol rubber substitute.
