Elastomers Selection Guide

The comparative properties listed in this selection guide are intended to help designers and users of rubber products to make preliminary choices of material. Final selections should be based on tests using samples of the elastomers chosen. The tests should simulate the actual service conditions expected, and samples should be properly compounded to optimize the particular properties desired.
