| Varglas S1600 Sleeving |
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 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.
