Vibsorb is a high capacity preformed cushioning pad fabricated using multiple layers of high quality cotton polyester duck fabric, completely impregnated with a high-grade nitrile compound. Finished Vibsorb Vibration Absorption pads will withstand compressive loads perpendicular to the plane of laminations of 10,000 pounds minimum per square inch without detrimental reduction in thickness or extrusion.
