Description
Varfil Sleeving is braided fiberglass coated with a polyester-modified polyvinyl chloride resin. The composite coating on this Class 130°C sleeving has improved properties over standard polyvinyl plastisol coatings with regard to chemical compatibility and solvent resistance (resists swelling in oil, xylol and trichloroethane). Some users prefer the slight degree of firmness found in Varfil when compared to Varflo (vinyl-coated fiberglass).
Specifications
Varfil Sleeving conforms to military specification MIL-l-3190/2, latest revision (Grade A); NEMA TF-1, Type 2; and ASTM-D876.
Under the Component Program of Underwriters Laboratories, all grades of Varfil Sleeving comply with VW-1 flammability requirements under UL File #E53690.
Applications
Varfil Sleeving finds wide acceptance by motor manufacturers as well as by motor repair shops. It is used to insulate leads in motors, transformers, generators and similar apparatus. Because of its toughness, dielectric strength, good electrical properties and resistance to soldering temperatures, Varfil also is used in electronic circuitry in measuring instruments, computers, etc. and for both original equipment and aftermarket automotive industry applications such as regulators, starters, alternators, etc.
Sizes
AWG #24 through 2 ” l.D. Other sizes subject to inquiry.
