Ultra High Fatigue Life Rubber by EPSG Inc.

MATERIALS: Engineered Plastics Solutions Group (EPSG) announced the release of a revolutionary rubber blend called DuraFlex^™. DuraFlex^™ has the highest known resiliency and fatigue life in the industry. EPSG material experts worked with Akron Rubber Development Laboratory Inc. (ARDL) to create a natural rubber blend that would survive in the toughest, most abusive shock and vibration applications. The resulting formulation is nothing short of spectacular. The Goodrich Flexometer test is an industry standard heat rise test whereby materials are exercised and the temperature rise of the material is measured. Lower temperature rise corresponds to longer fatigue life. For comparison, a general purpose natural rubber will experience a 12-14F rise. Typical long-life natural rubber blends will experience a rise of approximately 6F.  DuraFlex™ tested at a 0 degree rise.

EPSG has run repeated fatigue life tests on the material and has not been able to fail it in a customer application. The material is naturally a pearl white color but can be molded in black or most any other color. This allows for easy part identification, machine color matching, etc. Ideal applications are shock and vibration isolation such as engine mounting, cooling system mounting, motor mounting, and vibratory equipment applications. It is also ideal for military applications such as isolating equipment in aircraft, ships, tracked vehicles, and trucks. The material comes in a range of durometers.
