Novel flame retardant polymer blends
The work presented here involves the preparation of flame retardant plastics by blending Sb2O3 and halogen-containing substances with thermoplastic polymers like ABS and HIPS to impart flame retardancy to what are otherwise flammable plastics. While Sb2O3/halogen-compound additive systems are currently employed to produce flame-resistant commercial plastics, most employ brominated compounds as the halogen source. In this study, we have opted for a chlorine-containing halogen source. The novelty in this lies in the types of chlorinated compounds used (DDT and DDE) and the fact that chlorine containing halogen sources are generally thought to be inferior, in flame retarding ability, to brominated sources. Despite this, we have created polymer blends that contain more than 75 wt% commercial polymer and still rate as V-0 in the industry-standard UL-94 flame test. This, coupled with the low cost of chlorinated species, may yield a promising new class of flame-retarding materials.
