Abstract
Abstract This invention is directed to an extruded thermoplastic, thin-walled, high definition profile structure having a central hollow cross sectional member with at least two flange members extending perpendicularly therefrom and longitudinally therewith wherein at least one flange member extends from one side of the cross sectional member and at least one flange member extends from the other side thereof. Preferably, there are three flange members extending from one side forming channel-like recesses and one flange extending from the other side of the cross sectional member. Also included herein are particular thermoplastic resins that can be employed in making the profile structure of this invention. For example, the profile can be a composite comprising a substrate of acrylonitrile-butadiene-styrene and a thin outer layer of polyvinyl chloride or a blend of polyvinyl chloride and acrylic-styrene-acrylonitrile. The profile of this invention is suitable as frames for openings in buildings, particularly frames for windows, doors and the like.

Claim 1
Independent Claim
173 words
A thin walled, thermoplastic high definition profile structure suitable for building products comprising an essentially central hollow cross sectional member having at least two longitudinal flange members extending in a perpendicular orientation position to the central hollow cross sectional member, wherein at least one flange member extends perpendicularly from one side of the central hollow cross sectional member and at least additional flange member extends perpendicularly from the other side of the central hollow cross section member, said cross sectional member, said one flange member, and said additional flange member comprise a thermoplastic polymer material comprising a substrate and an outer weather and ultra violet light resistant layer, said thermoplastic polymer material having a glass transition temperature of greater than about 160° F., said substrate is a rigid acrylonitrile-butadiene-styrene polymer and said outer layer is a polymer selected from the group consisting of (a) an acrylic-styrene-acrylonitrile polymer, (b) a blend of an acrylic-styrene-acrylonitrile polymer with polyvinyl chloride, and (c) a blend comprising at least 50 percent by weight of an acrylonitrile-styrene acrylate polymer.
