ABSTRACT:
The method of compounding a high strength, cost-effective, composite of a high temperature, water sensitive, polar, polyamide-inide resin mixed with a talc, water absorbent/adsorbent filler. The method comprises raising said mixture to a temperature of about; 500.degree. F. to develop plasticity in said engineering resin. Thereafter there is added a lower temperature softening, water repellant, polypropylene resin and a compatibilizing additive. Finally all components are mixed in a mixing chamber sufficiently to obtain complete dispersion and homogeneity of the composite.
