Co-mingled Glass Fiber and Thermoplastic Resin Reinforcement Provides High Mechanical Properties with No Volatile Organic Compounds TOLEDO, Ohio, June 23 /PRNewswire-FirstCall/ -- Owens Corning (NYSE:OC), a world leader in glass fiber reinforcements and residential and commercial building materials, announced today that it has licensed its award-winning Twintex(R) reinforcement technology to Fiber Glass Industries, Inc., Amsterdam, N.Y. Twintex(R) technology will be used by Fiber Glass Industries to produce GLASS POLYPRO(TM) roving and fabrics that combine glass fibers and polypropylene filaments. The proprietary and ready-to-use thermoplastic and glass fiber technology is designed to produce reinforcements with high mechanical properties such as excellent stiffness-to-weight ratio and superior impact resistance. Twintex(R) technology also provides freedom of design and easily recyclable products. "We are delighted to establish another source of products made with Twintex(R) technology," said Marcio Sandri, vice president and managing director, Americas, for Owens Corning's Composites Group. "The additional availability of reinforcement products made with this innovative technology will extend its use in a variety of processes and markets." "We are proud to manufacture a new line of co-mingled glass and thermoplastic fibers using industry-leading technology," said Tom Bruce, director of sales and marketing at Fiber Glass Industries. "This will allow for continuity of supply in the U.S. for co-mingled glass and thermoplastic roving products, and also allow us to work with our customers to develop new applications for the products." Bruce said production of GLASS POLYPRO(TM) roving and fabrics by Fiber Glass Industries will begin in September. Until then, material needs will be provided by Owens Corning. Earlier this year, an application of Twintex(R) technology received one of the composites industry's highest awards. The honor, awarded at the JEC Composites Show in Paris, the world's largest exhibition for composites materials, was for the products and technology used to make window lineals. The breakthrough technology, using Twintex(R) co-mingled glass fiber and polymer reinforcements, eliminated the need for steel inserts to strengthen the parts, which allowed the manufacturer to eliminate a separate insertion step from the process.
