PVDF (polyvinylidene fluoride)

The appearance of polyvinylidene fluoride is translucent or white powder or granules. The molecular chains are tightly packed and have strong hydrogen bonds. The oxygen index is 46%, and they are nonflammable. The crystallinity is 65%~78%. The density is 1.17~1.79g/cm3, the melting point is 172°C, the heat distortion temperature is 112~145°C, and the long-term use temperature is -40~150°C.

 

Main features:

  1. Excellent mechanical properties, good toughness and wear resistance

  2. Excellent electrical insulation performance and radiation resistance

Application areas:

  1.Electronic and electrical industry: used as wire cover, cable sheath, printed circuit board, heat shrink tube, capacitor dielectric, microphone, earphone, speaker electret, non-solvent keyboard switch, ultrasonic device, high optical frequency generator Wait.

  2. In the chemical industry: making pumps, valves, pipe fittings, electrolytic diaphragm plates, filter membranes and gaskets, linings, corrosion-resistant coatings, etc.

  3. Weapon industry: used as piezoelectric fuze, propellant fuel seal, etc.

  4. Machinery industry: used as gears, bearings, etc.

  5. Construction industry: Decorative or protective coatings or films for indoor and outdoor buildings.

  6. Medical health: Because PVDF is non-toxic to the human body and has no exclusive effect in the human body, microporous membranes or hollow fibers can be made into artificial lungs, kidneys and other artificial organs.
