Description
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.
Specifications
Varglas S1600 Sleevings conform to NEMA TF-2 and will not burn and are made from glass fibers conforming to Military Specification MIL- R-60346 (latest revision), Type IV, Class 1 (continuous filament yarns).
Applications
Varglas S1600 Sleevings are used for thermal and mechanical protection in applications requiring stability under extreme temperature and corrosive environments.
Sizes
Types H, HO, HM and Untreated - AWG #26 through 2” I.D. Type ML - AWG #24 through 3/8” l.D.
Standard Color
Untreated - White only, Type H - Natural (silver) only, Types HO, HM and ML - Natural. Other colors made to order.
Standard Packaging
Coils - all 5 types. Spools where specified.
Cut pieces are available, subject to cuffing charges, in Types HO, HM and ML only.
