Abstract: A wire coating composition comprises polypropylene polymer or copolymer and magnesium hydroxide provided with a hydrophobic coating. The wire coating composition does not contain any halogen and is essentially free of phosphorus and phosphorous compounds and phosphorous salts. Furthermore the coating is free of polyethylene wax.

Abstract: PURPOSE: To obtain a polyolefin resin composition excellent in heat and aging resistances and useful for films for self-adhesive tape substrates of good workability by mixing a base comprising a specified olefin resin with a high-mol. wt. hindered phenol antioxidant and a zinc compound.CONSTITUTION: A resin composition prepared by mixing 100 pts. wt. resin base comprising at least one member selected from among a polyethylene, an ethylene/vinyl acetate copolymer, an ethylene/alkyl acrylate copolymer, an ethylene/alpha-olefin copolymer and a mixture thereof with 0.1-10 pts. wt. high-mol. wt hindered phenol antioxidant and 1-20 pts. wt. zinc compound. Examples of the zinc compound to be used are desirably inorganic compounds and include zinc borate and zinc oxide. As the high-mol. wt. hindered phenol antioxidant, one having a mol. wt. of 500 or above is particularly desirable from the viewpoint of nonblooming properties, etc.
