PVDF (polyvinylidene fluoride)
- Excellent chemical resistance
- UV and radiation stability
PVDF or polyvinylidene fluoride is a highly inert, semi-crystalline thermoplastic polymer. This material can be handled over a wide temperature range, from -20°C to + 130°C. It is very fire-resistant and remains unalterable even under a heat of 175°C. PVDF has outstanding chemical stability against most chemicals, including a wide range of aggressive chemicals such as halogens and oxidants, inorganic acids, aliphatics, aromatics and chlorinated solvents. However, the excellent chemical stability does not necessarily apply to strongly basic solutions or esters and ketones. In addition, it is very resistant to abrasion and remains stable under the action of UV and radiation.
PVDF is used in various fields such as the chemical industry for the manufacture of fittings, tanks and piping, but can also act as a protective barrier or insulator. It is also used in the electronics sector for the insulation of wires and piezoelectric elements.
