HNBR:Hydrogenated Nitrile Butadiene Rubber, also known as Highly Saturated Nitrile (HSN), is produced by hydrogenating acrylonitrile butadiene rubber (NBR).This process improves the heat and ozone resistance, increases tensile strength, and provides superior abrasion resistance. The result is a rubber polymer that performs superior to standard NBR in most sealing applications. Taking advantage of its inherent properties, HNBR can be compounded to provide excellent service life in applications such as oilfield, automotive, and refrigerants. Dynamic applications requiring long service life or in abrasive environments are especially well suited to HNBR. FDA grades are available. Internally lubricated compounds are superior for extended wear dry air applications.
FKM has the characteristics of high temperature resistance, oil resistance, high vacuum resistance, acid and alkali resistance, and a variety of chemical drugs. It has been applied to modern aviation, missile, rocket, space navigation, naval ships, atomic energy and other cutting-edge technologies and automotive, shipbuilding, chemical, petroleum, telecommunications, instruments, machinery and other industrial fields.
