Varfil sleevings are braided fiberglass coated with a polyester-modified polyvinyl chloride resin. The composite coating on this Class 130°C sleevings have 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).
Class 130 B
(-34°C to +130°C) (-29°F to +266°F)
Dielectric Strength Grade(s): A-1 B-1 C-1 C-2
Varfil sleevings conforms to military specification MIL – I – 3190/2, latest revision (Grade A); NEMA TF-1; Type 3; and ASTM D372.
Under the Component Program of Underwriters Laboratories, all grades of Varfil sleevings comply with VW-1 flammability requirements under UL File #E53690.
Varfil sleevings find 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. Varfil displays superior toughness, dielectric strength, good electrical properties and resistance to soldering temperatures. Varfil sleevings are also used in electronic circuitry in measuring instruments, computers, and for both original equipment and aftermarket automotive industry applications such as regulators, starters and alternators.
