Method Of Mixing Composite Filled Thermoplastic Resins
US Patent:
4980390, Dec 25, 1990
Filed:
Oct 23, 1989
Appl. No.:
7/462901
Inventors:
Norman Shorr - Pittsburgh PA
Clarence Wright - Houston PA
Clarence Wright - Houston PA
International Classification:
C08K 326, C08K 300
US Classification:
523 1
Abstract:
A method of mixing filled thermoplastic resins containing particles of resin and filler. The method comprises preheating to about 150 degrees to 250 degrees F. , at least the resin particles, and thereafter mixing until plasticized. The filler may also be preheated between 150 degrees and 350 degrees F. This method reduces the mixing time and improves the characteristics of the product.
Method Of Mixing High Temperature Composite Filled, Thermoplastic Engineering Resins
US Patent:
5137942, Aug 11, 1992
Filed:
Oct 31, 1990
Appl. No.:
7/607037
Inventors:
Norman Shorr - Pittsburgh PA
International Classification:
C08K 334, C08L 7700
US Classification:
523307
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.
