Abstract
A polymeric composition having a polymer content which tends to evolve deleterious acid compounds upon being subjected to elevated temperatures; the composition including selected particle matter which is present in an amount to combine with or otherwise neutralize essentially the entire evolved deleterious compound when the composition is subjected to elevated temperatures; the composition with or without plasticizers being useful as insulation or jacketings for electric wire and cable, as well as diverse molded or extruded products, including disposable items such as packaging or the like.
Claims12
A fireproof self extinguishing composition, comprising:
- a polymer which evolves hydrogen chloride at temperatures encountered in a fire;
- a plasticizing amount of a non-flammable plasticizer;
- and a material selected from the group consisting of the carbonates of calcium, barium, magnesium, strontium, sodium, potassium, lithium and mixtures thereof, said material having an average particle size which does not exceed 250 millimicrons and being present in an amount which is at least sufficient to combine with essentially the entire amount of hydrogen chloride which is evolved at temperatures which occur in a fire to thereby prevent evolution into the surrounding atmosphere of the hydrogen chloride when the composition is subjected to said temperatures.
