PVDF : The versatile fluoropolymer for corrosive environments

PVDF (polyvinylidene fluoride) is a semi-crystalline fluoropolymer renowned for its exceptional chemical resistance, thermal stability and good mechanical properties. It is used in a wide variety of sectors, including the chemical industry, construction, water treatment, electronics and food processing.

Its ease of machining and good temperature resistance make it a choice alternative to metals and other engineering plastics for equipment exposed to harsh conditions.
 

Excellent chemical resistance

• Insensitive to strong acids, bases and organic solvents
• Suitable for corrosive environments and aggressive fluids

Thermal stability

• Continuous service temperature: up to 150°C
• Punctually withstands peaks up to 200°C

Good mechanical performance

• High tensile strength and good modulus of elasticity
• Mechanical properties maintained over time

Low coefficient of friction

• Stable sliding behavior
• Reduces wear in moving parts

Insulating properties

• Excellent electrical insulation for electronic applications
• Combined with its chemical resistance, PVDF is ideal for wiring in aggressive environments
