Title:
LAMINATE FOR FORMING AND FORMED BODY
Document Type and Number:
Japanese Patent JPH0952305
Kind Code:
A
Abstract:

To improve the compression restoring properties, provide a good hand feeling and prevent the generation of recesses and projections by forming a foamed polyurethane sheet composed of a core layer with open cells and skin layers formed on both surfaces of the core layer and distributing micropores with openings on the outer face of the skin layer on which another skin layer is not laminated.

A laminate 11 for forming is formed by laminating a skin layer 12 composed of flexible thermoplastic resin integrally on one surface of a foamed polyurethane sheet 15. The polyurethane sheet 15 is composed of a core layer 14 with open cells 17 and skin layers 13 and 13' formed on both surfaces of the core layer, and micropores 19 with openings 18 are distributed at least on the whole of the outer surface of the skin layer 13 being in contact with a resin base material. The foamed polyurethane sheet 15 used for the laminate 11 for forming is composed of a flexible or semi-rigid polyurethane foaming body, and cells of the core layer 14 can be of microcell structure.
