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.
Type(s): 240
(-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.
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 oleoresin binder (natural or pigmented).
Type ML:
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.
Specifications
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).
Applications
Varglas S1600 sleevings are used for thermal and mechanical protection in applications requiring stability under extreme temperature and corrosive environments.
