摘要:
The invention relates to a cross-linkable, halogen-free, flame-resistant plastic mixture which can especially be used, in a cross-linkable state, for coating cables. The inventive plastic mixture comprises the following plastic components: (a) 3 to 50 weight parts (phr) of at least one ethylene copolymer from the group comprising ethylene vinyl acetates, ethylene ethyl acrylates, ethylene methyl acrylates or ethylene butyl acrylates, (b) 30 to 96 weight parts (phr) of a high-density polyolefin, especially a HDPE (High Density Polyethylene) having a density of >0.94 g/cm3, and (c) 1 to 20 weight parts (phr) of a polyolefin which has been grafted with a derivative of an unsaturated carboxylic acid, especially HDPE-g carboxylic acid derivatives. Components (a) to (c) together produce a total of 100 weight parts (phr) of plastic. The mixture also comprises the following components: (d) 40 to 250 weight parts (phr) of a filling material, and (c) 0.1 to 15 weight parts (phr) of a stabilizer system.
