CHEMICAL RESISTANCE AND FLUID COMPATIBILITY
KALREZ@ perfluoroelastomer parts combine the elastomeric properties of VITON” fluoroelastomer with the chemical resistance of TEFLON@ fluorocarbon resins. Due to its unique properties, KALREZ perfluoroelastomer parts should be considered for service in all applications and environments where dependable long-term service is desired, as well as in hot and/or aggressive environments which are beyond the serviceability of common elastomers. This guide is intended to provide assistance in determining the suitability of six commercially available elastomers-nitrile (NBR). ethylene propylene (EPDM), silicone (SI), fluorosilicone (FSI). vinylidene fluoride based fluoroelastomer (FKM) and KALREZ perfluoroelastomer-for service in over 1,600 chemicals and fluids. The criteria used for these ratings included volume swell resistance based on laboratory immersion testing, labora- tory aging tests. actual field experience and informed judgments based on experience in similar chemical groups.
The ratings for the five common elastomers are based on published literature and are offered for general com- parative purposes only-we cannot guarantee their accuracy nor assume responsibility for their use. The rat- ings for these five elastomers may be overly optimistic for elevated temperature and/or high concentration applica- tions since many are based on ambient temperature test- ing. Suitability of these elastomers for service at elevated temperatures rapidly diminishes since higher tempera- tures Increase the effects of chemicals on both the base polymer as well as the crosslink systems. Serviceability is further limited by the upper service temperature limit of each polymer, nominally 107°C/2Z50F, 149°C/3000F, 204°C/4000F, 190°C/3750F. and 204Y/400°F for NBR. EPDM. SI. FSI and FKM respectively-note that these limits are based on air oxidative stability; limits for specific chem- icals are often much lower. Additronally. these elastomers are commercrally available in different grades of polymer and can vary in compound Ingredients-different grades and compounds within a polymer class can have signifi- cantly different performance characteristics.
As an example, consider a specific case involving an FKM. whose upper service temperature limit is nominally 204°C/4000F. Many sources will show an ‘A” rating for FKM surtabrlity In toluene service, a common chemical. However, immersion testing of commonly available FKM o-rings at a slightly elevated temperature of 50°C/1220F for 168 hours shows a volume swell exceeding 24% and significant loss of physical properties-surely warranting a “C” rating. Similar tests with KALREZ perfluoroelastomer parts, however, show that the “A” rating is maintarned beyond 100°C/2120F. CHEMICAL RESISTANCE TABLES
