DWFR TUBING Dual Wall Heat Shrink Tubing Highly Flame-Retardant, UL VW-1 Rated • Highly flame-retardant with UL VW-1 flammability rating DWFR tubing from TE Connectivity (TE) is a highly flame-retardant, high-shrink ratio, adhesive-lined tubing made from a polyolefin jacket with a thermoplastic adhesive inner wall. It insulates and environmentally seals and protects components and other electrical connections and terminations. DWFR’s medium wall thickness provides increased mechanical protection. Its high shrink ratio allows DWFR to cover a variety of substrates with a limited number of tubing sizes. It is suitable for sealing and protection of connector-to-cable transitions and repairing damaged cable jackets. It can also be used to create and seal breakouts in harnesses. • 3:1 and 4:1 shrink ratios provide design versatility ELECTRICAL KEY FEATURES • Moisture-resistant seal • Withstands mechanical stress for increased product reliability APPLICATIONS • Household appliances • Provides excellent electrical insulation MECHANICAL • Medium wall jacket provides mechanical protection from abrasion and bending • Adhesive liner bonds to a variety of substrate materials, providing protection from moisture ingress TEMPERATURE RATING • Automotive • Minimum shrink temperature: 60°C [140°F] • Commercial electronics and communications • Full recovery temperature: 110°C [256°F] • Consumer products STANDARDS AND SPECIFICATIONS • Industrial equipment • Customer drawing: DWFR MATERIALS • Operating temperature: -40°C to 110°C [-40°F to 230°F] • UL 224 VW-1 • UL file E35586 • Irradiated polyolefin jacket • Submitted for CSA Certification • Thermoplastic adhesive inner wall ORDERING INFORMATION • Color: Black (-0) • Standard packaging (-STK): Cut pieces that are 1.2m [4ft] long.
