Varglas Non-Fray Sleeving is flexible, high-temperature secondary insulation made from closely braided, continuous filament fiberglass which has been heat-cleaned to remove impurities in the yarn and to retard fraying. There are four types available all of which are noncorrosive and nonflammable and not attacked by fungus. Type H: Heat cleaned only. Since it is not treated with sizing or pigments after heat cleaning, it is available only in the natural (silver) color.
Type HO: Heat cleaned and treated with an acrylic resin binder (natural or pigmented).
Type HP: Heat cleaned and treated with an acrylic resin binder (natural or pigmented) that is slightly more flexible than Type HO
Type HM: Heat cleaned and treated with an oleoresinous varnish binder (natural or pigmented).
Binders are applied to further retard fraying and to hold sleeving round for cutting. Types HO, HP and HM are available in a variety of colors which may be less vivid after exposure to 150°C. All four types are available in various wall thicknesses. All will serve as secondary insulation unaffected indefinitely through a temperature range from -60°C to 316°C and withstand up to 616°C for shorter periods. Since there is no impregnant that will provide dielectric protection at those extremes, these sleevings require heavy or multiple-wall thicknesses if used as primary insulation.
