Preparation and Evaluation of Diallyl Isophthalate Molding Powders Containing Aramid Fibers with Other Fillers

摘要

Nomex and Kevlar chopped fibers were used with:Solem 336SP, an alumina trihydrate powder, Fybex, a titanium silicate fiber or Ekkcel C-1000, a poly hydroxy ester powder, to formulate experimental diallyl isophthalate molding powders. One objective of the study was to obtain plastic moldings with higher heat distortion values than the diallyl phthalate based formulations. A second objective was to develop a molding powder that could be substituted for the asbestos filled diallyl phthalate product now produced at Mound Facility, thus eliminating OSHA restrictions on asbestos processing.
