DWFR TUBING Dual Wall, Heat Shrink Tubing Highly flame-retardant, UL VW-1 rated 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. DWFRs 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. KEY FEATURES ELECTRICAL Highly flame-retardant with UL VW-1 Provides excellent electrical insulation flammability rating MECHANICAL 3:1 and 4:1 shrink ratios provide design Medium wall jacket provides mechanical protection from versatility abrasion and bending Moisture-resistant seal Adhesive liner bonds to a variety of substrate materials, Withstands mechanical stress for in- providing protection from moisture ingress creased product reliability TEMPERATURE RATING APPLICATIONS Minimum shrink temperature: 60C 140F Household appliances Full recovery temperature: 110C 256F Automotive Operating temperature: -40C to 110C -40F to 230F Commercial electronics and communi- cations STANDARDS AND SPECIFICATIONS Consumer products Customer drawing: DWFR Industrial equipment UL 224 VW-1 UL file E35586 MATERIALS Submitted for CSA Certification Irradiated polyolefin jacket Thermoplastic adhesive inner wall ORDERING INFORMATION Color: Black (-0) Standard packaging (-STK): Cut pieces that are 1.2m 4ft long Optional special order packaging (-SP): Spool, varying lengths (consult TE for details) Ordering description: Specify product name, size, color and packaging.
