What is PVDF heat shrinkable tube?

    PVDF heat shrinkable tube is actually a heat shrinkable tube that is extruded and expanded using polyvinylidene fluoride resin copolymer. Its full name is polyvinylidene fluoride heat shrinkable tube. Polyvinylidene fluoride is also referred to as PVDF, so it is generally referred to as PVDF heat shrinkable tube. Compared with ordinary heat shrinkable tubes, the material has changed, and its production process is basically the same. It is manufactured through the three main steps of extrusion, radiation cross-linking, and expansion.

    Although PVDF heat shrinkable tubes and PE heat shrinkable tubes only change the materials, their physical and chemical properties are very different. PVDF has the characteristics of both fluororesin and general-purpose resin. The resin itself has good chemical corrosion resistance, high temperature resistance, oxidation resistance, weather resistance, and radiation resistance. It also has piezoelectricity, dielectricity, and thermoelectricity. It has special properties such as resistance, so PVDF heat shrinkable tube also has the above-mentioned excellent properties.

Advantages of PVDF heat shrinkable tube

1. The temperature resistance range of PVDF heat shrinkable tube is also very wide. It has the characteristics of high and low temperature resistance such as no brittleness at minus 55℃ and no deformation in high temperature environment of 175℃. It has good thermal stability.

2. The mechanical properties are also very excellent, with very good rigidity, hardness, wear resistance and creep resistance, high fatigue resistance under cyclic loading, and the mechanical strength is recognized to be higher than other fluoropolymers.

3. It is resistant to most chemical solvents and oils, has the property of not swelling when soaked in solvents and oils for a long time, has low adsorption properties, and has a very smooth surface.

4. PVDF heat shrinkable tubing can be produced and processed into medical grade products. Because it has biological inertness, low water absorption, low adsorption and non-toxic and bacterial resistance, it also meets the requirements of medical grade.

5. It is a heat shrinkable tube with high transparency and flame retardant. Transparent heat shrinkable tubes made of PE and EVA cannot meet the flame retardant requirements. If you need to be transparent and flame retardant, you can choose PVDF heat shrinkable tube to make up for it. The transparent heat shrink tube is not flame retardant.

    PVDF heat shrinkable tubes are also very versatile and are widely used in high-end fields such as electronics and electrical, aerospace, medical equipment, and military industry. As the source manufacturer of PVDF heat shrinkable tubes, Duwai controls the quality at all levels, and the quality is stable and reliable.
