The present disclosure relates generally to polymer structures, for example, suitable for construction products. The present disclosure relates more particularly to a thermoplastic construction product including a coextruded layer structure having a base layer including a first thermoplastic material, an outer layer including a second thermoplastic material, and an infrared-reflective intermediate layer that is coextruded with the base layer and the outer layer and is disposed between the base layer and the outer layer. In some embodiments the intermediate layer has a thickness of at least 30 micrometers. In some embodiments the infrared-reflective intermediate layer includes a reflective pigment dispersed in a matrix of one of the first thermoplastic material or the second thermoplastic material.

This invention relates to a surface finish manufacturing system and process and more particularly, but not exclusively, to a contrast surface finish manufacturing system and process for producing boards with a wood texture finish. The surface finish manufacturing system comprises a top layer and a bottom layer where part of the top layer is removed to expose part of the bottom layer.

A catheter is made by coextruding first and second molten polymers, wherein the second molten polymer forms a flexible inner core and the first molten polymer forms exactly two bands on opposite sides of the inner core. The inner core is braided, and a third molten polymer extruded onto the braid to form a flexible jacket that encloses the braid, the bands and the inner core. The bands are more rigid than the inner core, and they provide preferential in-plane bending.

The present disclosure relates to a film having light transmittance and a manufacturing method thereof. The film includes a Polyurethane (PU) surface layer, and a thermoplastic elastomer layer. The thermoplastic elastomer layer is disposed under the PU surface layer. The thermoplastic elastomer layer includes color masterbatch material. The color masterbatch material is between 0.1-1% weight. By controlling the amount of color masterbatch material in the thermoplastic elastomer layer, the film of the present disclosure has real color appearance and good light transmittance.
