There are significant differences between nitrile glue and hydrogenated nitrile glue in the following aspects:
Structure: Hydrogenated nitrile rubber (HNBR) is a special rubber obtained by special hydrogenation of nitrile rubber. This treatment process removes many double bonds in the hydrogenated nitrile rubber, making its structure more saturated.
Performance: While maintaining the good oil resistance of the original nitrile rubber, hydrogenated nitrile rubber also has better heat resistance, chemical corrosion resistance, ozone resistance and compression permanent deformation performance. The operating temperature range has also been significantly improved. The regular use temperature can reach 130℃ to 180℃, and the special formula can even reach 200℃ or higher. In addition, hydrogenated nitrile rubber also has the characteristics of high strength, high tear performance and excellent wear resistance.
In contrast, although nitrile rubber also has good oil resistance, wear resistance and cold resistance, it is not as good as hydrogenated nitrile rubber in terms of thermal stability and chemical resistance.
In general, hydronitrile rubber is superior to nitrile rubber in performance, especially in high temperature and chemical corrosion environment. Therefore, when choosing rubber materials, you can choose the appropriate rubber type according to the specific use environment and needs.
