  • High gloss high impact TPO coextrusion and method of making
    Patent number: 5972520
    Abstract: A high gloss, impact resistant material is made by coextruding a cap layer of a metallocene polyethylene and clarified random copolymer polypropylene onto a core layer. The coextrusion process is guided by a dual manifold die which reduces the interfacial instability of the melt streams as the cap layer is being applied. When thermoformed, the material retains its gloss and exhibits excellent low temperature impact resistance.
