COMPOSITION AND SIZE - This fiber glasses cloth is made from glass fibers woven into specific patterns. 0.2mm thick plain weave, Fiberglass mat measures about 50” wide, 12 ft/ 4 yd long, and weighs 6 oz/sq.yards FEATURES - This 6oz fiberglass cloth has features like high tensile strength, dimensional stability, high temperature resistance, rust resistance, insulation flame retardant, and chemical resistance RESIN COMPATIBILITY - This woven fiberglass cloth is compatible with Epoxy, polyester, and vinyl ester resin systems. This makes woven fabric for boat an essential product in the fiberglass repair kit EASY TO USE - Fiberglass repair cloth is lightweight & flexible that can be cut to the size as per your custom requirement, making fiberglass sheet easy to use with fiberglass resin for strong waterproof repair works VERSATILE USE - Fiberglass cloth can be used to repair holes or cracks in many surfaces, including metal, plastic, ceramic, wood, etc., great for use in boats, auto, craft, surfboards, tubs, pools, etc. Fiberglass Cloth 6 oz, Plain Weave 50" x 12 ft. / 4 yd. Long for Boat, Auto, Surfboard, Tub, Pool Repair, etc. Length: 12 Feet (4 Yards) Width: 50 Inch Weight: 6 Oz./sq.yard. (200 gsm) Fiberglass woven roving cloth is made from continuous E-Glass roving that is loosely woven into a heavy fabric. Fiberglass mats are suited for application in boats, pools, crafts, etc., and are compatible with polyester, epoxy, and vinyl ester resin systems. High Tensile Strength: Fiberglass cloth is one of the strongest textile fibers, having great specific tensile strength than steel wire of the same diameter, at a lower weight. Durability Being inert, fiberglass cloth is unaffected by sunlight, fungus, or bacteria. Dimensional Stability: Fiberglass cloth has low elongation under load, generally 3% or less. Glass fibers produce fabrics with excellent dimensional stability under various types of conditions. High Heat Resistance: Fiberglass cloth has excellent heat resistance at a relatively low cost. Fire Resistance: Fiberglass cloth is composed of inorganic materials and is non-combustible, a natural choice where flammability is of concern. Low Thermal Conductivity: The rapid heat dissipation of fiberglass cloth is particularly important in electrical insulation applications. Good Chemical Resistance: Like glass itself, fiberglass cloth is highly resistant to attack by most chemicals. Outstanding Electrical Properties: Fiberglass fabric withstands high temperatures and has low moisture regain. Along with its high dielectric strength and low dielectric constant, glass is of major importance and usefulness in electronics.
