O & G
    Other Standard Grades    
0090 95
Excellent Chemical resistance and outstanding resistance to Rapid Gas Decompression (RGD). Independantly tested and certified by MERL to meet Norsok    M-710 rev.2.  Achieved highest possible 0000 rating. Upper servie temperature 250°C.  O & G
1050LF 82
Best in class for hot water/steam and excellent amine resistance and enhanced compression set properties. Excellent with wet amines and offers low outgassing at high temperatures. Temperatures to 288°C    CPI
 3018  91 Similar to 1050LF but has higher hardness/modulus. Good in hot water/steam and amines. Offers the best high pressure extrusion resistance.
   CPI + O&G
 3065  90 Designed to function under extrusion at extreme pressure.Good all round chemical resistance + excellent resistance to sour oils & amines. Upper service to 288 deg C. Usually used to produce V Rings & custom parts, not O Rings.
 O & G
not O Rings
None filled compound with high purity. Good in Oxygen environment & excellent in ozone. Well suited to vacuum service and static application requiring low stress/low sealing force. Maximum upper temperature limit 275 deg C
  Pharmaceutical & high purity environments
Suitable for many applications and was one of the first materials to be developed in the Kalrez range. Outstanding hot air ageing properties with low compression set at high temperatures. Maximum operating temperature of 315 deg C but avoid water/steam & amines at high temps.
  General Purpose




70 (white)  

75 (black)           

Superior chemical resistance & low contamination in food & handling applications where FDA compliance is required. Suitable for WFI & SIP systems. Thermal stability upto 260 deg C which permits stage II sterilisation processes.
