Rubber Properties Table

Our rubber properties chart provides a guide for making initial decisions about the suitability of an elastomer for a given application or service environment, our technicians are available to help you make informed decisions.

Most of the main rubbers are included in the properties chart below although White Cross Rubber Products Ltd’s capability also extends to a wide variety of more specialist blends and formulations. The inherent characteristics of a polymer can be compounded in a range of hardnesses and its properties improved and extended by the inclusion of additives.
