HNBR o ring 24*3.1mm

      Hydrogenated nitrile rubber, abbreviated as: HNBR, or H-NBR. It is a new variety of nitrile rubber (NBR).

HNBR has achieved excellent heat resistance (resistance to 150 ° C high temperature) and ozone resistance while maintaining the excellent oil resistance of NBR. Its application has broken through the traditional field of NBR, making chlorinated polyethylene Special rubbers such as chlorosulfonated polyethylene are also subject to certain impacts. From an economic point of view, the HNBR sales price is still relatively expensive, but still much lower than fluororubber. At the same time, due to the low rigidity, good process performance and low density of HNBR, more fillers can be added, and the unit volume of HNBR products is only half of that of fluororubber, so it will become a substitute for special elastomers such as fluororubber. Although HNBR has been produced abroad for many years, its application fields are expanding, and it is still a blank in China. We should not miss the opportunity to develop HNBR. According to preliminary understanding, there are more than 2,000 second-stage wells in Daqing and Shengli Oilfields in China, which need to use submersible pumps to pump oil at a depth of 2000 meters and a temperature of about 140 °C. If the spindles are NBR, the use period is only a few months or even shorter. For example, the spindle of HNBR can be used for more than one year.
