TE introduces DWFR, dual wall flame-retardant tubing, a new UL VW-1 rated heat shrink tubing. DWFR is a highly flame-retardant, high shrink ratio, dual wall tubing consisting of a polyolefin jacket and a thermoplastic inner adhesive wall. DWFR is the first dual wall tubing product from TE meeting the stringent requirements of UL 224 VW-1 for flammability. DWFR provides excellent electrical insulation as well as a moisture-resistant seal.
