Chemical Resistance

For many applications, low volume swell/weight gain (change) of elastomers is critical for proper equipment operation. Excessive swell /weight gain (change) may cause permanent seal failure due to equipment hang-up, extrusion, etc. While other physical property testing may be needed to adequately define product performance in a particular application, volume swell/weight gain (change) is an excellent indi cator of resistance to chemical attack. Table1 provides chemical resistance (% volume swell) test data for Elastomers Part A in various acids, bases, solvents and water. Table 2 compares the weight gain and volume swell of Elastomers Part A versus standard FKM in anamine - based chemistry
