A new line of improved PVC alloys which deliver exceptional high-heat performance and enhanced weathering for dark-colored profiles in a wide range of climates has been introduced by PolyOne Corporation. The range, Geon(TM) HTX Ultra, is consistent with PolyOne's commitment to develop innovative, value-added polymer solutions. The enhanced technology enables building materials manufacturers to offer a wider range of colors for window profiles, fence, deck and rail components, siding, and other building and construction applications. Geon HTX Ultra alloys are applicable for use as a solid profile, a cap layer or for substrate/cap combinations.
Profiles made with Geon HTX Ultra alloys can withstand temperatures up to 195 degrees F without warping or sagging. As a result, profile manufacturers will be able to offer more choices of dark-color building materials, which are becoming more popular for new construction and renovation. Geon HTX Ultra products provide superior weatherability, better flow, and have a lower specific gravity, which leads to lower part weight compared with conventional weatherable, rigid PVC compounds. These alloys are further noted for their improved impact performance when compared with conventional high- heat PVC and CPVC compounds, as well as being processing-friendly.
