Polyvinylidene fluoride, commonly abbreviated to PVDF, is a semi-crystalline thermoplastic fluoropolymer that is most commonly used in such things as:
electrical applications in aircraft,
electrical insulation materials.
Being invented in 1969 by Dr. Heijji Kawai, PVDF became known as a tough, stable fluoropolymer with distinct engineering advantages and a good performance-to-cost ratio. Also, as an organic ferroelectric material, PVDF 1000 and its copolymers typically show better overall performance than their counterparts.
