Abstract
Abstract The utilization of thermoplastic rubbers in the fabrication of body molding trim, such as automotive trim, is made possible in combination with polyvinyl chloride by the provision of an intermediate portion comprising a polyolefin having the property of providing non-delaminating adherence to the thermoplastic rubber and the polyvinyl chloride, thus permitting the use of thermoplastic rubber as the basis of a molding trim while making available the versatility and fabrication techniques already developed for polyvinyl chloride, including the use of decorative finishes such as mylar, bonded to the polyvinyl chloride.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
121 words
A composite trim section having a first extruded portion of a thermoplastic rubber, a second portion substantially longitudinally co-extensive therewith being of polyvinyl chloride film not generally adherable with said first portion, said first and second portions each having a surface area in facing relation with the other portion, an intermediate portion located between said facing area portions of a third material bonded in heat sealed relation to said thermoplastic rubber constituting the sole securing agent between said first and second portions consisting of a single component polyolefin being in itself adherently compatible with said first and second portions, to provide substantially non-delaminating adhesion between said portions, said polyvinyl chloride film having a decorative finish layer in adherent protective relation therewith.
Claim 2
Dependent Claim
121 words
A composite trim section having a first extruded portion of a thermoplastic rubber, a second portion substantially longitudinally co-extensive therewith being of polyvinyl chloride film not generally adherable with said first portion, said first and second portions each having a surface area in facing relation with the other portion, an intermediate portion located between said facing area portions of a third material bonded in heat sealed relation to said thermoplastic rubber constituting the sole securing agent between said first and second portions consisting of a single component polyolefin being in itself adherently compatible with said first and second portions, to provide substantially non-delaminating adhesion between said portions, said polyvinyl chloride film having a decorative finish layer in adherent protective relation therewith.
Claim 3
Dependent Claim
16 words
The trim section of claim 1, said decorative finish layer being a film of polyethylene teraphthalate.
Claim 4
Dependent Claim
11 words
The trim section of claim 1, wherein said polyolefin is polypropylene.
Claim 5
Dependent Claim
25 words
The trim section of claim 1, wherein said polyvinyl chloride film is a tape having said polyolefin secured in adhering relation to one face thereof.
Claim 6
Dependent Claim
23 words
The trim section of claim 4, wherein said polyolefin is bonded to said extruded portion of thermoplastic rubber simultaneously with the extrusion thereof.
