| Varglas Viton® 231 Sleeving |
Description
Varglas Viton® 231 Sleeving is a braided Fiberglas®/modified Viton® cornposite with exceptional physical and electrical properties. It has excellent abrasion and cut-through resistance and offers improved flexibility throughout a wide operating temperature range. Its resistance to solvents, both aromatic and aliphatic; fuels, including JP-5; and oils, including Skydrol; place this fluoroelastomer above other available polymer-coated fiberglass braids.
Specifications
Varglas Viton®
231 Sleeving conforms to, and is listed on the Qualified Products List
(QPL) for, MIL-l-3190/7, latest revision (Grade A), and exceeds the
requirements of NEMA TF-1 and ASTM-D372.
Under the component
program of Underwriters Laboratories, Varglas Viton® 231 Sleeving complies
with VW-1 flammability requirements under UL File #E53690. It is
incorporated in systems work, per UL Safety Standard 1446, to facilitate
product acceptance by UL.
Applications
Varglas Viton®
231 Sleeving is used in DC generators and motors to reduce arcing problems
and elsewhere when the need to maintain a silicone-free environment is
important. Its flame resistance and excellent resistance to abrasion make
it ideally suited for the insulation of leads and connections of critical
electrical components as well as for wire harnesses in areas where
continuous operating temperatures run as high as 220°C. Varglas Viton®231
is also used in transformers where resistance to high impingement velocity
oils is required and, generally, where better solvent and oil resistance
is needed.
Sizes
AWG #24 through
3” I.D. Other sizes subject to inquiry.
Standard Color
Black, white and
natural.
Standard
Packaging
Coils, spools or
36” lengths at manufacturer’s option, unless otherwise specified. There is
no cutting charge for 36” lengths, but lengths other than 36” are subject
to cutting charges.
Sizes over 1” l.D. are generally supplied in
36” lengths.
