Products in the Owens Corning High-Performance Reinforcements platform achieve performance characteristics that are similar to other high-performance reinforcements but at a substantially lower cost. Based on revolutionary patented technology that includes new glass batch formulas and enhanced melting and forming capability coupled with proprietary sizing chemistry, the innovative products are designed for superior mechanical properties, such as strength, strain and modulus, and offer significantly higher thermal and corrosion resistance properties when compared to E-glass fibers.
Thermopreg™ product is a unique and ready-to-use Thermoplastic glass reinforcement, designed for high mechanical properties, such as excellent stiffness/Weight ratio and superior impact properties. Thermopreg™ product also provides with efficient and environmental friendly process conditions, high freedom of design and is recyclable. Thermopreg™ products are made of continuous commingled E-glass and thermoplastic filaments. Thermopreg™ product range includes fabrics and plates.
For application in cement or concrete, glass fibers are required to be Alkali Resistant (AR). Cem-FIL® fibers are manufactured from a specially formulated glass composition with an optimum level of Zirconia (ZrO2) to meet this requirement. Cem-FIL® glass exhibits a high degree of chemical resistance and was specifically developed to resist the very high alkalinity produced by the hydration of Ordinary Portland Cement. Cem-FIL® AR glass fibers have high tensile strength and modulus, do not rust and are easily incorporated into concrete mixes.
Our glass reinforcements are made in various forms in order to make them suitable for a variety of processes and to provide desired thermo-mechanical and electrical properties. Rovings are produced either directly from the bushing by drawing a large number of filaments (direct roving), or by assembling several strands in parallel, with no twisting (assembled roving). Chopped strands are basic strands generally cut to lengths from 3 to 12 mm; these products have numerous applications. Continuous filament mats are felts of continuous filaments distributed in uniform layers as they leave the bushing and held together by a binder. Chopped strand mats are felts or mats consisting of glass strands chopped to lengths of mostly 50 mm and held together by a binder which is soluble in styrene.
