High-Bulk Modulus Cellular Rubber for Weapon Applications

Abstract

Rubber compounds based on Neoprene, oil extended EPDM and a fluorosilicone/silicone blend were developed for use in the molding of cellular materials that have a limited amount of cell structure. The high-bulk modulus cellular materials had lower tensile strength, elongation, hardness, and modulus than the solid controls, as was expected. Several of the EPDM-based cellular materials had reasonably high strength. The age resistance of the materials was as good or better than the controls when based on compression deflection results. The compression and bulk moduli of the cellular materials were lower than the solid controls, but were considerably higher than commercial grades of cellular rubber. Several cellular materials that have been developed should perform better in such applications as gaskets, springs, and buffers than commercially available cellular materials.
