O-ring is suitable for installation on all kinds of mechanical equipment, in the specified temperature, pressure, and different liquid and gas media, in the state of static or moving sealing.
In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, and all kinds of instruments and meters, a large number of applications of various types of sealing components.
Products Materials
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.
HNBR O-Rings are most commonly in Green or Black, are also avaialable in Yellow and red special compounds.
