Door profile

Geloy . [GE Plastics] Acrylic-styrene-acrylonitrile terpolymers outdoor weatherable polymer used in the building and constraction market for window and door profiles, gutters and downspouts, mobile home skirting, and capstock for siding. 

Window and door profile manufacturers form another large industrial segment that uses WPGs. Although more expensive than unfilled PVG, wood-filled PVG is gaining favor because of its balance of... 

Since the consumption of PVC worldwide is about 30 M tonnes ear, it should be reasonable to assume a global heat stabiliser consumption of approximately 750,000 t/y. There is expected to be a decline in lead stabiliser consumption, however, and a 3%/y growth in the tin type, with 4% growth in mixed metal stabilisers. As an example, the lead previously used in wire and cable and in window and door profiles is being replaced by mixed metal stabilisers. Tin is expected to remain the most important PVC heat stabiliser in North America for some time. 

Korad films from Polymer Extruded Products, are weatherable, wood-grain, acrylic laminating films for outdoor window and door profiles and for adhesive-free bonding to polypropylene sheet for thermoformed products. 

Heat stabilizers are targeted exclusively at PVC. Plasticizers are almost as dependent on PVC as heat stabilizers. Lead stabilizers have served the PVC industry as heat stabilizers. The European Commission has highlighted concerns about the dangerous nature of lead stabilizers which should be phased out, but did not indicate a specific timetable. The commission also highlighted that lead stabilizer would not be approved for use in PVC pipes after 2003. In America, unlike in Europe, window and door profiles were stabilized with tin stabilizers. However, in Asia, lead stabilizers still are in use along with PVC.
