Polyurethane Fiberglass Sleeving (Class “F”) consists of a polyurethane varnish securely bonded to its
supporting fiberglass braid by a dip coating process. It is designed to remain flexible over wide
operating temperature (-30°C to 155°C).
Its resistance to hydrocarbons, transformer oils, weathering, fungus, and chemical attack provides
many advantages to lead ends in electrical systems. PU sleevings give good performance in high
temperature applications which is better than Alkyd Coated sleevings.
