Abstract
Abstract The present invention provides a polyurethane foam interior finishing material having a facing, characterized in that the material comprises a laminate of a thermoplastic synthetic resin facing material and an expanded pad layer, the expanded pad layer comprising a semi-rigid polyurethane foam reinforced with long glass fibers, the long glass fibers being present in the pad layer primarily in the vicinity of the rear side thereof, the finishing material having no core. The invention also provides a process for preparing the material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
68 words
A polyurethane foam interior finishing material having a facing, characterized in that the material comprises a laminate of a thermoplastic synthetic resin facing material and an expanded pad layer, the expanded pad layer comprising a semi-rigid polyrethane foam reinforced with long glass fibers, the long glass fibers being present in the pad layer primarily in the vicinity of the rear side thereof, the finishing material having no core.
Claim 2
Dependent Claim
68 words
A polyurethane foam interior finishing material having a facing, characterized in that the material comprises a laminate of a thermoplastic synthetic resin facing material and an expanded pad layer, the expanded pad layer comprising a semi-rigid polyrethane foam reinforced with long glass fibers, the long glass fibers being present in the pad layer primarily in the vicinity of the rear side thereof, the finishing material having no core.
Claim 3
Dependent Claim
39 words
An interior finishing material as defined in claim 1 wherein the long glass fibers are in the form of a mat prepared by spirally arranging the fibers into at least one layer and applying a binder to the layer.
Claim 4
Dependent Claim
65 words
A process for preparing a polyurethane foam interior finishing material having a facing, characterized by setting a thermoplastic synthetic resin facing material in a lower die, injecting a semi-rigid urethane form solution into the die over the facing material, subsequently setting long glass fibers on the upper portion of the lower die, thereafter closing the lower die with an upper die and curing the solution.
Claim 5
Dependent Claim
65 words
A process for preparing a polyurethane foam interior finishing material having a facing, characterized by setting a thermoplastic synthetic resin facing material in a lower die, injecting a semi-rigid urethane form solution into the die over the facing material, subsequently setting long glass fibers on the upper portion of the lower die, thereafter closing the lower die with an upper die and curing the solution.
Claim 6
Dependent Claim
37 words
A process as defined in claim 3 wherein the long glass fibers are in the form of a mat prepared by spirally arranging the fibers into at least one layer and applying a binder to the layer.
