Material Choice Guide To Selecting Rubber Compounds
Porter Seal Company is pleased to present this "Material Choice Guide To Selecting Rubber Compounds" to provide a convenient reference for proper elastomer selection.
This information should be used only as a general guide, as the ratings are based primarily on published literature from various polymer suppliers such as Du Pont, Dow Corning and General Electric Co. as well as other rubber manufacturers. We do not guarantee the accuracy and assume no liability for the use thereof.
There are many variable factors to be considered before accepting a general elastomer compound for a particular service. Because of the variations in compounds and the various affect of changes in temperature, durometer and service conditions, it is the policy of Porter Seal Company that the customer should always test and determine the suitability of the particular elastomer compound for its particular application requirements.
