High Performance Window Frames and Gutters Made from Extruded Plastic

Published on December 7, 2010 at 6:58 PM

When Zhongcai Profiles Co. Ltd., Zhejiang, China, needed an advanced materials solution to manufacture color-rich, high-performance window profiles for its building and construction customers, the company turned to SABIC Innovative Plastics. The solution was Geloy* XTW resin, a high-end acrylonitrile-styrene-acrylate (ASA) resin that has become the standard for excellence in co-extruded window profiles, gutters, siding and roofing for the building and construction industry.

When used as a cap layer over polyvinyl chloride (PVC) and other materials, Geloy XTW ASA resin maintains its color and gloss up to 10 times better than competitive products. This resin demonstrates SABIC Innovative Plastics’ unmatched ability to repeatedly develop breakthrough materials that give customers a significant differentiator in challenging market sectors.

Window Profiles Made by Zhongcai Profiles Using SABIC Innovative Plastics’ Geloy* XTW Resin

“Our highly weatherproof profiles made with Geloy XTW ASA resin extruded over PVC are among the company’s premier products and have been a great success with our customers,” said Li Yugen, general manager, Zhongcai Profiles. “The Geloy XTW ASA resin provides outstanding weathering performance and resistance to discoloration for extended service life. This product has helped us become the third-largest profile manufacturer in China.”

Sustainability and Competitive Differentiation

Another important reason why Zhongcai Profiles switched to Geloy XTW resin is sustainability. China’s goals to reduce carbon footprint, conserve energy and promote recycling are better served with co-extruded Geloy XTW/PVC resin profiles than with aluminum. The plastic window profiles provide better insulation than aluminum, helping to prevent the loss of heat from buildings. These recyclable resins also provide long useful life to conserve resources.

Using Geloy XTW resin, Zhongcai Profiles is in an excellent position to take advantage of China’s projected 30 percent annual growth in the window profiles market by offering a differentiated product with improved aesthetics, performance and weather resistance.

“With Geloy XTW resin we have taken weatherable resin technology far beyond conventional ASAs to achieve a balance of aesthetics and performance unequaled in the industry,” said Jos Braat, global Geloy resin product marketing director, SABIC Innovative Plastics. “This material is a near perfect solution for today’s residential construction requirements because it provides fresh and dramatic aesthetics, long useful life and low maintenance. By choosing products made with our new Geloy XTW ASA resin material, building owners and contractors can take pride in the beauty and durability of a new or remodeled home.”

Sun, Rain or Snow Are No Problem for Geloy XTW ASA Resin Technology

SABIC Innovative Plastics has developed proprietary processes and compositions for Geloy XTW ASA resin that significantly improve weathering performance while maintaining ductility and ease of processing. Compared to traditionally used ASAs, this high-performance material holds its true color as much as 10 times more effectively.

This technology can play an important part in creating and maintaining the beauty and value of residential property. It withstands ultraviolet light, moisture, extreme temperature, chemicals and environmental pollutants.

In addition, Geloy XTW ASA resins are available in a much wider range of colors than standard ASA grades. For example, SABIC Innovative Plastics has developed an elegant copper shade and is currently working on a new low-gloss material. The full palette includes earth tones such as green, brown and gray that are popular in Asia, and bright chromatic colors for a design statement.

Geloy XTW ASA resins can be co-extruded over PVC – helping to eliminate “chalking” – as well as acrylonitrile-butadiene-styrene (ABS). It offers good flow to accommodate complex window profile designs, and delivers excellent impact resistance.

Geloy XTW ASA resins can also be used in other building and construction applications, such as doors, fences, wall panels, and pool and spa parts. Zhongcai Profiles is considering expanding its use of the resin into co-extruded PVC pipe.
