ABSTRACT:
Flame retardant reaction injection molded (RIM) or structural RIM (SRIM) resins having improved time retardant properties may be produced by the addition of a halogenated vinyl resin. Suitable halogenated resins include polyvinyl chloride (PVC) and chlorinated PVC (CPVC). A synergist may be present to further enhance the fire retardant properties, which may be antimony trioxide, antimony pentoxide and the like. The resulting RIM resins may also have glass fibers or other materials present therein to provide structural improvements. The physical properties of RIM and SRIM compositions do not suffer from the addition of these flame retardant additives.
