fiberglass geogrids

详情

Fiberglass geogrids are the best choice for asphalt reinforcement as it has all the advantages shown by the fiberglass yarns: 1. Chemical Resistance Inorganic fiberglass textile fibers will not rot, mildew or deteriorate. 2. Dimensional stability The fiberglass yarns used in manufacturing Fiberglass geogrids will not stretch or shrink as a result of changes in atmospheric conditions. Nominal elongation at break is **4%. 3. Good Thermal properties Fiberglass fabrics have a low coefficient of thermal expansion and relatively high thermal conductivity. The melting point is ca. ***0C. This ensure stability when subjected to the excessive heat of a paving operation. 4. High Tensile Strength Fiberglass yarn has a high strength-to-weight ratio. Pound for pound, fiberglass yarn is twice as strong as steel wire.
