  Rubber (Elastomer) Service Selection Guide
Rubber, otherwise known as an elastomer or polymer is available in a number of molecular configurations or families. Our Elastomer Selection Guide is designed to let you examine the general properties of any family of elastomer (polymer). The ratings reflect the average performance of an elastomer family. Compounding and manufacturing techniques may improve or degrade the performance level noted in the guide.

"We do not want to sell you our elastomer, we want to sell you the right elastomer."
