| 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.
