TE Connectivity (TE)is introducing SWFR, a halogen-free, UL VW-1 rated single wall heat shrink tubing. SWFR is a highly flame-retardant, 2:1 shrink ratio, polyolefin tubing with a low shrink temperature for fast application. Advances in material science and manufacturing efficiencies allow SWFR tubing to be offered at an attractive price point. It is offered in thin wall (X2) and very thin wall (X4) versions.
