Varglas S1600 Sleeving
Varglas S1600 sleevings are a high-strength, high-temperature sleevings produced from special S-2 Glass® fibers. In addition to enhanced dielectric and mechanical properties, S1600 provides thermal protection beyond the limits of conventional sleevings 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®, is free of boron, therefore, in the hostile atmosphere of a reactor, will not decompose to form gaseous products.
There are five types of S1600 sleevings, all of which are noncorrosive, nonflammable and impervious to fungus attack.
(-70°C to +482°C)(-94° to +900°F)
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.
Not heat cleaned or treated, but containing its original sizing so it is available only in white.
Heat cleaned only. Since it is not treated with sizing or pigments after heat cleaning, it is available only in the natural (silver) color.
Heat cleaned and treated with an acrylic resin binder (natural or pigmented).
Heat cleaned and treated with an oleoresin binder (natural or pigmented).
Heat cleaned and treated with Pyre ML® binder (natural or pigmented) Natural & Green Only.
Since there is no coating 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.
