Description
Varglas Viton® 231 Sleeving is a braided fiberglass/modified Viton® composite 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 ” l.D. Other sizes subject to inquiry.
Standard Color
Black, White & 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.
