Polyvinylidene Fluoride: A Versatile and Useful Polymer Material

Polyvinylidene fluoride Introduction to PVDF Polyvinylidene fluoride or PVDF is a highly versatile fluoropolymer first produced in the late 1930s. Commonly used for its combination of desirable material properties, PVDF finds applications in areas such as coatings, linings, membranes, and electrical insulation. Chemical Structure and Properties PVDF is a linear fluorocarbon polymer with the chemical formula (CH2CF2)n. The repeating monomer unit contains one carbon-hydrogen bond and one carbon-fluorine bond arranged in a trans-configuration. This chemical structure gives PVDF several unique properties. Polyvinylidene Fluoride has exceptional chemical resistance to corrosion from acids, bases, and organic solvents. It maintains its mechanical properties over a wide temperature range from -150°C to +150°C. PVDF is also highly resistant to ultraviolet light and weathering. In addition, PVDF has a high melting point of around 160-180°C depending on its exact crystallinity...
