PVDF Guide: Properties, Applications and Design Considerations
What is PVDF plastic?
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).
PVDF has very good machinability and therefore there are few restrictions to consider when machining.
Sharp cutting tools are recommended to avoid chipping during machining.

Industry Examples: Electronics | Medical | Pharmaceutical | Food technology | Mechanical engineering | Chemical & petrochemical | Scientific | Nuclear
Typical Components & Applications: Chemical tanks | Laboratory equipment | Solar power systems | Pumps | Food machinery components | Bearings
- 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
Note For Designers:
PVDF is an expensive thermoplastic and therefore should be reserved for applications requiring the highest strength, purity and chemical and heat resistance.
If the superior tensile stress and compressive strength are not required, or a higher operating temperature is desired, PTFE may be considered as an alternative.
