These charts are meant to be used as a guide only in selecting material for appropriate chemical compatibility. Before permanent installation, be sure to test the equipment with the appropriate chemicals and under the specific conditions of your application.

In an ever-changing business environment with fierce competition, managers need to constantly seek out new ways to improve their products or components. Continuous improvement is an important ingredient for innovation, which in turn ensures staying competitive and profitable.

This document lists some of the factors affecting tolerances. In general, the degree of reproducibility of dimensions depends upon the type of tooling and rubber used, and the state of the art.

The Rubber Manufacturers Association (RMA) has developed tolerance tables with ranges to provide communication between user and provider across a wide range of industries. These are helpful when designing and producing a part. You can also consult the RMA article on factors affecting tolerances of molded rubber products.

These data sheets outline physical properties, heat aging, liquid effects, and compression modulus (based on ISO7743) for the material samples included in our Sample Kit. They are a selection of standard compounds we use everyday to make your custom rubber parts.
