What is PVDF Heat Shrink Pipe and what are its advantages  

一What is PVDF Heat Shrink Pipe

PVDF heat shrink tube is actually a type of heat shrink tube made by extruding and expanding polyvinylidene fluorine copolymer resin. Its full name is polyvinylidene fluoride heat shrink pipe. Polyvinylidene fluoride is also abbreviated as PVDF, so it is usually called PVDF heat shrink tubing. Compared with ordinary heat shrink tubes, the material has changed, but their production processes are basically the same, all of them are produced in three main steps: extrusion, radiation binding and expansion.

Although PVDF heat shrink pipe and PE heat shrink pipe only change the material, their physical and chemical properties are significantly different from each other. PVDF combines the characteristics of fluoro resin and general resin. In addition to excellent chemical corrosion resistance, high temperature resistance, oxidation resistance, weathering and radiation resistance, the resin itself has special properties such as pezoelectricity, dielectricity and thermoelectricity. Therefore, PVDF heat shrink pipe also has the above-mentioned excellent properties.

二, Advantages of PVDF Heat Shrinkable Pipe

1.The temperature resistance range of PVDF heat shrinkable pipes is also very wide. It has the characteristics of not cracking at -55 degrees and not deforming at 175 degrees high temperature, and has good heat resistance.

2.Its mechanical properties are also extremely excellent, featuring very good rigidity, hardness, wear resistance and creep resistance. It is highly resistant to cyclic fatigue and its mechanical strength is widely recognized as superior to other fluoropolymers.

3.It is resistant to most chemical solvents and oils, and has the property of no swelling after long-term immersion in solvents and oils. In addition, it has low adsorption and a very smooth surface.

4.Heat-shrinkable PVDF pipes can be recycled into medical products. Due to biological inertness, low water absorption, low adsorption, as well as non-toxicity and bacterial resistance, they also meet the requirements for medicinal products.

5.At present, it is a thermal compound with relatively high transparency and fire retardant ability. Transparent heat-shrink pipes made from PE and EVA materials do not meet fire retardant requirements. If both transparency and fire resistance are needed, you can choose PVDF heat shrinks, which fill the non-fire resistance gap of clear heat shrinks.

Heat-shrinking PVDF pipes also have a wide range of applications and are widely used in high-end fields such as electronics and electrical engineering, aerospace, medical and military industries.
