SWFR Heat Shrink Tubing

TE Connectivity (TE) introduces its SWFR tubing. SWFR is a highly flame-retardant, 2:1 shrink ratio tubing. Constructed of irradiated, cross-linked polyolefin, it insulates and mechanically protects components, electrical connections, and terminations. SWFR promotes a X2 (thin wall tubing) and X4 (very thin wall tubing) product offering. The thicker wall of the X2 offers better protection, while the space-saving thinner wall of the X4 permits denser packing of protected components and a faster shrink time. Both types are halogen free, allowing use in enclosed spaces where toxic gasses from burning materials containing halogens is undesirable.
