ABSTRACT:
Flexibilized vinyl halide polymers and copolymers having improved flame retarding and smoke suppressing as well as physical and electrical properties are described. The compositions are characterized by an unusual combination of ingredients comprising a base polymer flexibilized with chlorinated polyethylene, flame and/or smoke suppressants, stabilizers and plasticizers. The compositions exhibit improved flame and smoke suppression and low brittleness temperature over that of conventional fire and smoke suppressed PVC.
