Selection Guide
This selection guide is a guideline. Always consult our technical engineers, as different concentrations of media could have a negative effect on the physical properties of the elastomer.
1 = Excellent- minimal volume increase and/or change in physical properties
2 = Good-small volume increase and/or change in physical properties
3 = Moderate-acceptable amount of volume increase and/or change in phisical properties
NR = Not Recommended/Excessive volume increase and/or change in physical properties
