175°C Operating Temperature


WEICO's Kynar is an irradiated, thin-wall, heat-shrinkable tubing offering a high degree of mechanical strength and high temperature resistance. When heated in excess of 175°C, it will shrink to fifty percent of its supplied diameter. Fabricated from polyvinylidene fluoride, the tubing has outstanding abrasion resistant and cut-through properties in combination with high dielectric strength. Kynar tubings are recommended for shrink-fit protection and strain relief of wires, solder joints, terminals and connections. Suggested applications include automotive wiring, jackets, fuse coverings and military wire markers. Because the tubing is transparent, it affords see-through inspection and identification when used as jacketing for components such as resistors and capacitors. It is semi-rigid and highly resistant to most industrial fuels, chemical and solvents. Kynar tubings are readily marked by hot-stamp and print-wheel equipment.


SKY Kynar tubing has a 2:1 shrink ratio. When freely recovered, the tubing will shrink to 50% of its supplied diameter. SKY tubing meets MIL-I-23053/8, MIL-I-23053/18, Class 1 and AMS-3632. SKY tubing is rated for continuous operation from -55°C to+175°C.
