Abstract: A coextruded polymer molding product includes a notched structural carrier and a polymer seal material over the structural carrier. The structural carrier has notches along its length A first plurality of specific regions of the structural carrier have notches. A second plurality of specific regions of the structural carrier are relieved from having notches. The notched regions and relieved regions are arranged with respect to each other such that consecutive notched regions are spaced apart at non-uniform intervals to provide desired bending characteristics for conforming to a specific molding application.

Abstract: A window assembly for an automotive vehicle includes a division post formed by a co-extrusion process to include integrally-formed window pane seals. Upper and lower ends of the division post are joined or assembled to a flexible seal band such that the post and seal band completely surround a fixed window pane. The window assembly is simple and inexpensive to manufacture.

Abstract: Weather stripping for use in sealing an interface between selected vehicle portions is made using a thermoplastic material such as TPV with a supercritical fluid introduced during the manufacturing process to provide a microcellular structure. The microcellular structure of one example implementation of this invention includes a cell density in a range from about 109 to about 1015 per cubic centimeter. Average cell sizes preferably are less than 2 microns. A preferred range in one example is between about 0.1 micron and about 1.0 micron. The inventive design provides superior performance with cost savings compared to rubber weather stripping.
