PVDF High‑Temperature Heat‑Shrink Tube (2:1 Shrink Ratio)

Our PVDF high temperature heat shrink tube is manufactured from imported modified polyvinylidene fluoride resin. It is transparent, flame retardant and designed for long-term operation under 175℃ high temperature. This tubing delivers outstanding resistance against abrasion, cut, most fuels, industrial oils, solvents and chemicals. It is widely used to protect solder joints, terminals and connecting wires that are exposed to high heat, fuels and chemical corrosion. It adopts 2:1 shrink ratio, shrink temperature at 175℃, rated voltage 600V, wide working temperature range from -55℃ to 175℃. The standard color is transparent, so users can visually check the condition of internal connections after shrinking. Custom specifications are available for bulk orders.

>> Selection Guide

●Measure the outer diameter of the component (solder joint / terminal) you need to cover, select the tube whose fully shrunk inner diameter is smaller than the component OD.

●Confirm working environment: choose PVDF tubing if there is high temperature, oil, solvent or abrasion requirement.

●This tube requires heating to 175℃ to complete shrinking, heat gun or oven is needed.

●Standard transparent color, custom specifications available for large quantity orders.
