Low-Temperature Traction Rubber Sole Compound for Dms Combat Footwear

摘要

A new direct molded sole rubber compound designed primarily to give better traction at low temperature, and on snow and ice, than the present standard vinyl-modified Buna N rubber compound was successfully developed by utilizing Styrene-Butadiene rubber (SBR), type 1502. The vulcanizates of this new compound exhibited good physical properties which are comparable with the physical properties exhibited by the present standard sole compound. In addition, this new compound also displayed excellent ozone resistance and good low-temperature behavior - a property which makes this compound more suitable for wear on snow and ice. Furthermore, the test results on the finished boot samples showed that the new SBR compound has satisfied not only the curing conditions imposed by the CEMA and Wellco process but also the physical requirements, except for solvent resistance, which are specified in Military Specification, MIL-B-43154, for the standard direct molded sole (DMS) combat boot.
