Product Details

HNBR o ring seal retains excellent oil resistance of the original NBR o ring, but also got very good heat resistance (high temperature resistant to 150 ℃) and ozone resistance.The use field of HNBR o ring seal has broken through the traditional areas of NBR.And the chlorinated polyethylene , Chlorosulfonated polyethylene and other specialty rubber has also been impacted due to HNBR o ring seal. From an economic point of view, material of HNBR o ring seal sales price is still expensive for now, but HNBR o ring seal is still much lower than price of  fluorine rubber o ring. At the same time,HNBR o ring seal got advantage due to the low rigidity of HNBR, good process performance and low density.HNBR o ring seal can add more filler than the other rubber material. Besides the unit volume of HNBR o ring seal is only half of fluoroelastomers o ring.Therefore HNBR o ring seal will become a substitute for special elastomers such as fluoroelastomers. Although HNBR o ring seal has been produced in foreign countries for many years and its application fields have been expanding constantly.However HNBR o ring seal are still blank in the country. We should seize the opportunity to develop HNBR o ring seal . According to a preliminary understanding, there are more than 2,000 wells in Daqing and Shengli Oilfields in China that use submersible pumps to pump oil at a well depth of about 2,000 meters and a temperature of about 140℃. In the case of NBR spindles, the service life of nbr o ring is only a few months or less.If we use HNBR o ring seal , the use life will up to more than one year. Rubber parts manufacturer in Nanjing,who need annual HNBR more than 30 tons. In the manufacture of HNBR o ring seal , NBR catalytic hydrogenation technology is the key.the solution hydrogenation of NBR o ring of harsh technical conditions, Lanhua has been conducting this research, due to low recovery of rhodium, the cost is relatively high. The research of hydrogenation and hydroformylation of water-soluble biphasic catalysts focuses on the separation, recovery and recycling of noble metal catalysts. Once the application of these catalysts is extended to the hydrogenation of polymers, they can be used For the hydrogenation of NBR o ring, we have synthesized two water-soluble phosphine ligands and an attempt is under way.
