N1210-90 Low Compression Set, Peroxide-Cured Nitrile

N1210-90 combines excellent compression-set capability with explosive decompression resistance

N1210-90 is a 90 durometer, peroxide-cured nitrile with excellent compression set and good explosive decompression resistance (ED), combined with high temperature service capabilities. Usually, in the course of formulating any explosive decompression resistant seal material, it has been necessary to sacrifice much of the material s compression- set performance. Parker s N1210-90 however, offers the seal user good ED properties and excellent compression-set resistant capabilities with higher temperature handling characteristics.
