PVDF

PVDF offers excellent chemical resistance to a wide range of substances including acids, bases, solvents and oils making it suitable for harsh environments and applications.

Having high dielectric strength, it is an excellent electrical insulator so is often used in high voltage applications and in the production of components used in such areas.

It is a piezoelectric material, generating charge when mechanically deformed or subject to pressure. This property is utilised in sensors, transducers and energy harvesting devices.

Its high UV resistance makes it suitable for external applications.

Low density together with its other beneficial properties are the reasons it is used where weight is a consideration such as aerospace and motor sport applications.

It has a higher melting point than many other thermoplastics and retains its properties at higher temperatures.

Extruded up to 3m in length from 5mm diameter up to 100mm diameter, rods are produced specifically for machining precision components.

Sheets are available from 10mm to 60mm thick.

Typical components made from PVDF rod

• Specialist sealing components such as O-rings and seal elements where chemical resistance and good physical properties are needed.
• Bearings in low friction chemical resistant applications
• Pump components – impellors, housings etc
• Valve components controlling the flow of aggressive and high temperature fluids
• Fittings and connectors in chemical processing systems
• Electrical insulators
• Laboratory equipment such as analytical instruments
• Medical devices – precision machined parts requiring biocompatibility
• Aerospace components
• Semiconductor production – parts where chemical resistance and purity are essential.
