Glass Fiber

Used as insulation for wire in cloth or tape form, or in continuous fine lengths. It has a high tensile strength, a high resistance to extreme heat and is un­affected by acids (except hydrofluoric), oils and corrosive vapors. Glass yarns are used as a braiding material in the braiding phase of wire manufacture. Glass fibers are also used as an insulating film where they are bonded to the conductors via a thermosetting varnish. Fiberglass is a registered trade name for a material of this type.
