RESIN MATRIX FOR CHEMICAL EMBOSSING AND METHOD FOR PRODUCING CHEMICALLY EMBOSSED, CALENDERED NONHALOGEN RESIN SHEET

摘要

PROBLEM TO BE SOLVED: To provide a resin matrix for chemical embossing; a method for producing a chemically embossed, calendered nonhalogen resin sheet; especially, a nonhalogen flooring material which is enhanced in three-dimentional feeling, quality feeling and design effect by the development of the so-called chemical embossing synchronizing foamed and non-foamed parts to a pattern.;SOLUTION: This resin matrix for chemical embossing comprises a nonhalogen resin of which the melt viscosity at 200°C is 5,000-8,000 (Pa.s) at a shear rate of 10 (1/S) and the melt tension at 200°C is 5-10 (g) under such a measuring condition that the diameter of a piston is 10 (mm), the diameter of a nozzle is 1 (mm), the speed of 20 (m/min) and a take-over speed is 20 (m/min).;COPYRIGHT: (C)2004,JPO
