Fiberglass Roving Yarn

Product Description

Fibers produced from high purity (*9.*5%) SiO2. High silica and quartz fibers can be made into rovings or yarns, or woven into fabrics similar to ordinary fiber glass. However, high silica and quartz compared to fiber glass differ in thermal properties. High silica and quartz have very low coefficients of linear thermal expansion, can be heated to ***5°C (***0°F) and plunged into water without damage. The difference between high silica and quartz fibers is the cost and strength. High quality quartz needed for quartz fibers, which is fairly rare, is mined mainly in Brazil, while the raw material for high silica fiber is the same as ordinary glass fiber (common silica sand). The-high temperature strength of quartz fiber is considerably stronger than that of the high silica fiber.
