Dual Wall Heat Shrink Tubing Meets UL VW-1 Requirement

DWFR tubing products combine flame-retardant and moisture-resistant capabilities for wide range of applications.

September 08, 2015

TE Connectivity (TE) introduces the DWFR (dual wall, fire-retardant) product line; its first dual wall heat shrink tubing products to be rated for the UL VW-1 flammability test specified by the UL 224 standard. The DWFR tubing products’ highly flame retardant polyolefin jacket and a thermoplastic inner adhesive wall provide excellent electrical insulation and mechanical protection. When properly installed, the tubing shrinks to create a moisture-resistant seal. The DWFR tubing products’ high heat-shrink ratios of 3:1 and 4:1 enable designers to use just a few tubing sizes across numerous applications – from home appliances to industrial controls to automotive.
