Definition

ChEBI: A polymer composed of repeating 1,1-difluoroethyl units.

Industrielle Verwendung

The fluorohydrocarbons are of two kinds: polyvinylidenefluoride (PVF2) and polyvinyl fluoride(PVF). Although similar to the other fluoroplastics,they have somewhat lower heatresistance and considerably higher tensile andcompressive strength.
PVF2, the toughest of the fluoroplastic resins,is available as pellets for extrusion andmolding and as powders and dispersions forcorrosion-resistant coatings. This high-molecular-weight homopolymer has excellent resistanceto stress fatigue, abrasion, and to coldflow. Although insulating properties and chemicalinertness of PVDF are not as good as thoseof the fully fluorinated polymers, PTFE andFEP, the balance of properties available inPVDF qualifies this resin for many engineeringapplications. It can be used over the temperaturerange from –73 to 149°C and has excellentresistance to abrasion.

Industrielle Verwendung

The properties are generally similar to those ofthe other fluorinated resins: relative inertness,low dielectric constant, and thermal stability(up to about 150°C). The resins (PVF2 resins)are, however, stronger and less susceptible tocreep and abrasion than TFE and CTFE resins.
Applications of polyvinylidene fluoride aremainly as electrical insulation, piping, processequipment, and as a protective coating in theform of a liquid dispersion.

Industrielle Verwendung

PVDF can be used with halogens, acids, bases, and strong oxidizing agents, but it is not recommended for use in contact with ketones, esters, amines, and some organic acids.
Although electrical properties of PVDF are not as good as those of other fluoroplastics, it is widely used to insulate wire and cable in computer and other electrical and electronic equipment. Heat-shrinkable tubing of PVDF is used as a protective cover on resistors and diodes, as an encapsulant over soldered joints.
Valves, piping, and other solid and lined components are typical applications of PVDF in chemical-processing equipment. It is the only fluoroplastic available in rigid pipe form.
Woven cloth made from PVDF monofilament is used for chemical filtration applications. A significant application area for PVDF materials is as a protective coating for metal panels used in outdoor service.
A recently developed capability of PVDF film is based on the unique piezoelectric characteristics of the film in its so-called beta phase.
When compressed or stretched, polarized PVDF generates a voltage from one metallized surface to the other, proportional to the induced strain.
