PLASTERING MATERIAL BASE CLOTH AND PLASTERING MATERIAL USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a plastering material base cloth being excellent in the fitness to the body, free of emission of a poisonous gas in the incineration after the use and relatively inexpensive, and a plasting material using the same. SOLUTION: An elastic film is constituted of a composition which contains 0-25 wt.% of an olefin copolymer component (A) being a copolymer of ethylene and a 3-10Cα-olefin and 100-75 wt.% of a thermoplastic elastomer component (B) being at least one kind selected from a crystalline olefin-ethylene butylene-crystalline olefin block copolymer, a 1-butene-α-olefin copolymer and an elastomeric polypropylene. The permanent elongation of the film measured according to JIS K 6301 is 50% or below. The plastering material base cloth is constituted of a composite elastic film prepared by laying an elastic nonwoven fabric on at least one surface of the elastic film. The plastering material uses the same. COPYRIGHT: (C)2004,JPO
