The North American market has probably commercialized the widest variety of rigid PVC formulations for building and construction in both residential and commercial settings. These are very competitive markets that have been the focus of much product innovation and improvement over the years. Specialty Minerals Inc. (SMI) has carefully tracked this path of innovation and has developed functional filler products to meet the requirements of demanding applications in profiles, siding, pipe and conduit .
PVC window profiles sold in the United States should be certified by the American Architectural Manufacturers Association (AAMA), which sets performance standards for PVC profiles and products. Use the link below to reach their website for further information.
Suppliers developing profile products for import (windows, door frames, soffits, facia, rain gutters and drains, fencing, decking, and decorative profiles) may find several changes in the technology of stabilization and extrusion, as well as demanding requirements in thermal stability, weathering stability, and impact requirements. To produce profile parts that meet demanding impact requirements with (typically) thin wall thicknesses and surface gloss requirements, formulators will want to evaluate Tuffgard®, Ultra-Pflex®, Super-Pflex®, and Super-Pflex® MS precipitated calcium carbonates (PCCs) to achieve the balance of properties required for any specific-end application.
