Description

ABSTRACT:
Provided is a method for producing and a soft-rubbery matrix material composed of 0.3-70 micron particles of a 50,000-300,000 molecular weight cross-linkable polymer dispersed in a fluxable elastomer where the polymer's softening point temperature exceeds the elastomer's fluxing temperature and the polymer and elastomer are combined and mixed at a temperature maintained above the fluxing temperature of the elastomer but below the softening point temperature of the polymer.
