PVDF is a fluorinated semi-crystalline thermoplastic which is obtained by polymerizing vinylidene fluoride. Without any additives, it has the intrinsic stability inherent to fluoropolymers even when exposed to harsh environments, providing the user with a unique combination of properties resulting in longer equipment life.
In addition to the PVDF homopolymers, which are recognized worldwide for their excellent performance in a variety of applications, Solvay Specialty Polymers has developed a wide range of VF2-HFP copolymers, and VF2-CTFE copolymers to respond to specific needs of the market.
Loss on Drying
PVDF grades are available in a wide range of melt viscosities as powders and pellets. It can be processed using techniques applicable to standard thermoplastics:Extrusion, Injection, compression and transfer molding Machining .Drying of resin before processing is usually not necessary Care must be taken to eliminate "hang-up" areas where molten resin can collect and thermally decompose if residence time is excessive .
The chemical inertness varies between the fluoropolymers such as PTFE, FEP, PFA and MFA exhibitchemical inertness to a wider range of chemicals than do the partially fluorinated polymers such as CTFE (or PCTFE) and ECTFE.
At elevated temperatures, PVDF can be dissolved in organic solvents such as esters and amines, which allows PVDF to be applied as corrosion-resistance coatings on chemical process equipment and architectural panels.
Parts made of PVDF display great resistance to mineral and organic acids, aliphatic and aromatic hydrocarbons, alcohols and halogenated solvents.
