Abstract
Abstract A process for extruding resilient, impact resistant thermoplastic strips having a metallic appearance by providing a non-metallic film strip of a material selected from the group consisting of polysulfones and polyether sulfones and having a vapor deposited metallized surface, the film strip having melting and deformation temperatures higher than those of a transparent thermoplastic to be extruded thereon and a resiliency and an elasticity at least as high as the resiliency and elasticity of such transparent thermoplastic when extruded thereon and, while feeding such film strip through a cross-head die, extruding the transparent thermoplastic about the metallized film strip and the resilient, impact resistant thermoplastic strip having a metallic appearance produced thereby.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
159 words
In a process for extruding resilient, impact resistant thermoplastic products with at least one visible region having a metallic appearance, the steps comprising providing a non-metallic film strip of a material selected from the group consisting of polysulfones and polyether sulfones and having at least one metallized surface, said non-metallic film strip with said metallized surface thereon having melting and deformation temperatures higher than the melting and deformation temperatures of the transparent thermoplastic material to be extruded thereon and a resiliency and an elasticity at least as high as the resiliency and elasticity of such transparent thermoplastic when extruded thereon and, while feeding said film strip through an extrusion die with said metallized surface facing in the direction where, in the extruded product, said metallic appearance is to be visible, thermally extruding around said metallized surface film strip said transparent thermoplastic material thereby forming from said film strip and said transparent thermoplastic material a flexible, impact resistant thermoplastic product.
Claim 2
Dependent Claim
159 words
In a process for extruding resilient, impact resistant thermoplastic products with at least one visible region having a metallic appearance, the steps comprising providing a non-metallic film strip of a material selected from the group consisting of polysulfones and polyether sulfones and having at least one metallized surface, said non-metallic film strip with said metallized surface thereon having melting and deformation temperatures higher than the melting and deformation temperatures of the transparent thermoplastic material to be extruded thereon and a resiliency and an elasticity at least as high as the resiliency and elasticity of such transparent thermoplastic when extruded thereon and, while feeding said film strip through an extrusion die with said metallized surface facing in the direction where, in the extruded product, said metallic appearance is to be visible, thermally extruding around said metallized surface film strip said transparent thermoplastic material thereby forming from said film strip and said transparent thermoplastic material a flexible, impact resistant thermoplastic product.
