Abrasion-resistant flame-retardant composition

An abrasion-resistant flame-retardant composition comprising:

• (i) 100 parts by weight of a polymer component containing:
• (A) 50-90% by weight, based on the total polymer weight, of a polyolefinic resin having a maximum peak temperature (Tm) of higher than 125.degree. C. as measured by differential scanning calorimetry (DSC);
• and
• (B) 10-50% by weight, based on the total polymer weight, of a polyethylenic resin or rubber having a maximum peak temperature Crm) of lower than 125.degree. C. as measured by DSC;
• and
• (II) 30-200 parts by weight of an inorganic flame retardant
• said polymer component (I) containing 10.sup.-8 -10.sup.-5 gram equivalent based on 1 g of the polymers, of at least one functional group;
• incorporated on the polymer by graft modification, and wherein
• said component (A) is at least one member selected from HDPE and PP:
• said component (B) is at least one member selected from VLDPE, LLDPE, LDPE, EVA having a vinyl acetate content of 5-30% by weight and EEA having an ethyl acrylate content of 5-30% by weight;
• a functional group-containing polymer is an ethylene/.alpha.-olefin copolymer modified with maleic anhydride and having a density of 0.86 to less than 0.97 g/cm.sup.3 ;
• and said inorganic flame retardant (II) is at least one member selected from magnesium hydroxide and aluminum hydroxide.
