Flame resistant reinforced composites

摘要

A fire resistant thermosetting resin composite formulation comprising an effective amount of a flame suppressant additive. The thermosetting resin used in the formulation can be a polyester resin. The flame suppressant additive is a polyvinyl chloride powder which may be obtained as a reaction product of an emulsion polymerization, or alternatively, it may be obtained from recycled products containing significant amounts of polyvinyl chloride. The additive can be used in an amount of from 1% by weight to about 75% by weight based on the amount of an inorganic filler material that may be present in the formulation.
