Varglas S1600 Sleeving is a high-strength, high-temperature sleeving produced from special S-2 Glass® fibers which, in addition to enhanced dielectric and mechanical properties, provide thermal protection beyond the limits of conventional sleeving made from E-glass fibers.Although both S-2 Glass® and E-glass fibers have excellent resistance to all types of nuclear radiation, S-2 Glass®, unlike E-glass, is free of boron and, therefore, in the hostile atmosphere of a reactor, will not decompose to form gaseous products.There are five types of S1600 Sleeving, all of which are noncorrosive, nonflammable and impervious to fungus attack.
Untreated: Not heat cleaned or treated, but containing its original sizing so it is available only in white.
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 HM: Heat cleaned and treated with an oleoresinous binder (natural or pigmented).
Type ML: Heat cleaned and treated with Pyre ML® binder (natural or pigmented).
Binders are applied to retard fraying and to hold sleeving round for cutting. Types HO, HM and ML are available in a variety of colors which may be less vivid after exposure to 150°C. All five types are available in various wall thicknesses as well as with multiple walls. All will serve as secondary insulation unaffected indefinitely through a temperature range from -70°C to 482°C and withstand up to 950°C for shorter periods. Since there is no impregnant that will provide dielectric properties at those extremes, these sleevings require heavy or multiple-wall thicknesses if used as primary insulation.
Varglas S1600 Sleevings conform to NEMA TF-2 and will not burn and are made from glass fibers conforming to Military Specification MIL-Y-1140H Class C Form 1 (continuous filament yarns).
Varglas S1600 Sleevings are used for thermal and mechanical protection in applications requiring stability under extreme temperature and corrosive environments.
Types H, HO, HM and Untreated - AWG #26 through 2” I.D. Type ML - AWG #24 through 3/8” l.D.
Untreated - White only, Type H - Natural (silver) only, Types HO, HM and ML - Natural. Other colors made to order.
Coils - all 5 types. Spools where specified.
Cut pieces are available, subject to cutting charges, in Types HO, HM and ML only.
