Fiberglass Sewing Threadis widely used in sewing of high temperature resistant fabrics, and filter bags, also used as electric insulation material, thermal insulation material, filler for electric cables, fire proof material, wicks, sealing material, winded electric heating wires, and heat elements.
Properties:
It features high tensile strength, good sewing property and high temperature textiles. It is necessary fitting material used to sew filter bags on industrial high-speed sewing machine, also used to sewing weak alkali-resistant weave and sewing high temperature textiles. It can be used below 300centigrade for a long period ,with high tensile strength.
