Main Specification of PVDF Rod:
1:Colour: Nature White
2:High Temperature Resistance
3:Outstanding Chemical Resistance
4:Low Coefficient of friction
The appearance of PVDF is translucent or white powder or granules. The molecular chains are closely arranged and have strong hydrogen bonds. The oxygen index is 46%, non-combustible, crystallinity is 65%~78%, and density is 1.77~1.80g/cm3. The melting point is 172 ° C, the heat distortion temperature is 112 to 145 ° C, and the long-term use temperature is -40 to 150 ° C. PVDF is a high-strength, corrosion-resistant material that is commonly used to make water pipes.
PVDF offers excellent corrosion and chemical resistance at both ambient and elevated temperatures (up to 280°F). PVDF is also inherently UV stable, mechanically tough, abrasion and flame resistant. PVDF are highly chemically resistant fluoropolymers used in piping, tubing, vessel fabrication, machined valves and fittings, nozzles and other items for corrosive fluid handling.
Applications of PVDF Rod: semiconductor, LCD related devices and other fields of electronic industry, chemical equipment, food processing machines, packaging machine parts, pipes, seals, pump parts, rotary discs, valves, slide rails, etc. Suitable for petrochemical, chemical, metallurgical, food, paper, textile, pipe, seal, pump parts, rotary disc, valve, stop valve, extractor, gear, pipe connection, slide rail. The manufacture of components in the pharmaceutical and atomic energy industries.
Piezoelectric properties of PVDF Rod
PVDF is an organic piezoelectric material, also known as piezoelectric polymer. This kind of material and its material are flexible, low density, low impedance and high voltage constant. They have been widely used in ultrasonic measurement, pressure sensing, ignition and detonation. The disadvantage is that the piezoelectric strain constant is low, which makes it very limited as an active transmitter.
