FIRE RETARDANT POLYPROPYLENE LAMINATE

摘要

PROBLEM TO BE SOLVED: To provide a fire retardant polypropylene laminate using a regenerated resin in larger quantities and excellent in strength and appearance. SOLUTION: A laminate is obtained by laminating a surface layer and a back layer both of which comprise a polypropylene resin based on a virgin polypropylene resin on both surfaces of an intermediate layer comprising a polypropylene resin containing regenerated polypropylene and the thickness ratio of surface layer/intermediate layer/back layer of the laminate is set to 8-15/70-84/8-15 and all of those layers contain 13-17 wt.% of a fire retardant.
