Wire protection kynar PVDF heat shrinking clear sleeve
TZRS-PVDF-(2X) UL Transparent resistors protection PVDF tubing is normally designated as kynar tubing, is a cross-linked, thin-walled, heat-shrinkable tubing offering a high degree of mechanical strength and high-temperature resistance. Fabricated from polyvinylidene fluoride, the tubing has outstanding abrasion resistance and cut-through properties in combination with high dielectric strength. It is inherently flame retardant, semi-rigid and highly resistant to most industrial fuels, chemicals and solvents. When heated in excess of 347°F (175°C), TZRS-PVDF-(2X)-B tubing rapidly shrinks to a skintight fit.
Approval: UL, VW-1, File No.E249362
Meet: RoHS, SAE-AMS-DTL-23053/18
Operating temperature: -55°C to + 175°C
Minimum fully recovery temperature: 175°C
TZRS-PVDF-(2X)-B tubing is typically used 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 allows see-through inspection and identification, and is ideal for use as a jacketing for components such as resistors and capacitors. The tubing is readily marked by hot-stamp and print-wheel equipment.
TZRS-PVDF-(2X)-B tubing has a 2:1 shrink ratio. When freely recovered, the tubing will shrink to 50% of its as-supplied internal diameter. The recovered wall thickness is proportional to the degree of recovery. The operating temperature range is from -55°C (-67°F) to 175°C (347°F), with a shrinking temperature minimum of 175°C (347°F).
