PVDF Machining

A Guide to PVDF CNC Machined Parts: Properties, Applications and Design Considerations

What is PVDF?

PVDF (polyvinylidene fluoride) is a high performance engineering plastic. It is a relatively new fluoropolymer best regarded for its chemical resistance. Although similar to PTFE, the mechanical features such as tensile stress and compressive strength are notably higher. Where PTFE trumps PVDF is in resistance to high temperatures (up to 300°C as opposed to 150°C for PVDF).

Main Attributes of PVDF:

Outstanding chemical resistance to acids and alkali
High density
Mechanical strength and toughness
Very low moisture absorption
Good UV and weather resistance
Flame retardant
Very good weldability
Food compliant
Wide operating temperature range (-50°C to 150°C)
Excellent dimensional stability
Good electrical insulating properties
Low thermal conductivity
