“…The resistance of polyethylene to ignition and combustion is increased principally by adding derivatives of halogens, phosphorus and boron and synergistic antimony (VI) oxide, which give rise, apart from a considerable reduction in flammability of the products, to the release of highly toxic and very corrosive smoke products [1-7, 18, 19]. These agents are current being replaced by non-halogen-containing compounds that are free of this drawback, including aluminium hydroxide and magnesium hydroxide [2,4,[19][20][21][22][23][24][25][26].…”
