Properties of poly(vinylidene fluoride)

Abstract

The properties of fluorocarbon plastics have made them desirable for numerous new applications. Poly(vinylidene fluoride) (PVF2) can be easily extruded into films or fibers or injection molded into a variety of shapes. It was found that crystallinity, molecular weight distribution and polymer structure are important in establishing resin properties. Highly crystalline PVF2 with a narrow Gaussian molecular weight distribution gives specimens with optimum physical and chemical properties.

“…It is highly resistant to chemicals and is not degraded by irradiation [2], properties which lead to its initial uses as dispersion coatings and in the aerospace industry in the 1960's. Its ease of moulding, coupled with superior mechanical and chemical properties, have been increasingly exploited in the chemical industry, where it is now an accepted engineering material [7].
