Chinese polyvinylidene fluoride rods, the English name Polyvinylidene fluoride is extruded into rods with PVDF resin at high temperature. It is a fairly pure polymer. It does not contain ultraviolet stabilizers, heat stabilizers, softeners, lubricants or Additives such as flame retardants. The oxygen index is 46%, flame retardant, crystallinity is 65%~78%, density is 1.79~1.83g/cm3, melting point is 188℃, heat distortion temperature is 120~151℃, long-term use temperature is -140~160℃. Due to the chemical inertness of PVDF, it hardly reacts with any medium. It is especially suitable for the transmission of pure water systems and pure chemical reagents in the semiconductor industry.
Main features
High temperature resistance (can work continuously at 150 degrees), excellent resistance to chemical corrosion and hydrolysis, outstanding UV resistance and weather resistance. High mechanical strength, good rigidity, good creep resistance, good sliding and wear resistance, inherent low flammability, and good electrical insulation performance.
shortcoming
Smoke containing fluorine when burned, not easy to stick
Application field
Due to its good chemical resistance, processability, fatigue and creep resistance, PVDF is one of the best materials for pumps, valves, pipes, pipe fittings, storage tanks, and heat exchangers in the fluid processing system of petrochemical equipment as a whole or lining. one. Its good chemical stability and electrical insulation properties enable the manufactured equipment to meet TOCS and flame retardant requirements. It is widely used in the storage and transportation of high-purity chemicals in the semiconductor industry, semiconductors, liquid crystal related devices and other electronic industries. In the field of chemical equipment, food processing machinery, etc.
Piezoelectric performance
PVDF is an organic piezoelectric material, also known as piezoelectric polymer. [1] This type of material and its materials have the advantages of flexibility, low density, low impedance and high voltage constant (g), etc., and they are developing very rapidly. Nowadays, underwater acoustic ultrasonic measurement, pressure sensing, ignition and detonation, etc. Aspect to be applied. The disadvantage is that the piezoelectric strain constant (d) is too low, which limits its use as an active transmitting transducer.
