PURPOSE: To provide a novel title composition suitable for foaming with high foaming ratio, giving a foamed article having excellent flame-retardancy and tensile elongation, and leaving a large amount of self-coagulating ash when burnt, by adding hydrated metal oxide powders to a specific polyethylene resin composition. n CONSTITUTION: A composition composed of (A) 100 parts by weight of a polyethylene resin composition composed mainly of (a) 10W75 parts by weight of a polyethylene having a density of 0.910W0.945 (g/cm 3 ) and a melt index of 0.01W2.0 (g/10min), and (b) 90W25 parts by weight of an ethylene copolymer, for example an ethylene/vinyl acetate copolymer, and (B) 80W250 parts by weight of hydrated metal oxide powders such as aluminum oxide powders. n USE: Raw material of film, pipe, etc. Extrusion coating of electrical wire, metal pipe, etc. n COPYRIGHT: (C)1980,JPO&Japio |
