ABSTRACT:
Flameproof moulding compositions, which are based on polyolefins and made from a pulverulent blend comprising a polyolefin as its essential ingredient and a plurality of flame-retardant ingredients. The flame-retardant ingredients comprise red phosphorus and at least one organic nitrogen compound which carbonizes after inflammation. The moulding compositions contain the flame-retardant ingredients in a total proportion of at most about 30 weight %. Red phosphorus and organic nitrogen compound are used in a quantitative ratio between 99:1 and 1.99.
