A Guide to PVDF CNC Machining

Characteristics of PVDF

PVDF (polyvinylidene fluoride) is a fluoropolymer with excellent heat resistance and chemical resistance. Among fluoropolymers, it stands out for having the highest dielectric constant and strong mechanical strength. It has a very smooth feel, excellent water repellency, low moisture absorption, and good resistance to surface contamination.

Common applications include food processing machinery and semiconductor manufacturing equipment.

• Excellent chemical resistance

• Excellent mechanical strength

• Excellent sliding performance and wear resistance

• Excellent weather resistance

• High dielectric constant

• Electrical insulation

• Flame retardant

• Minimal moisture absorption

Types of PVDF

In addition to the base grade, PVDF is available in specialty grades with enhanced performance characteristics.

• Base grade

• Conductive grade

• Carbon fiber reinforced grade

Material Selection Notes

PVDF resists most chemicals at room temperature but has limited resistance to certain substances such as acetone and caustic soda. Chemical compatibility should always be verified, and testing in the actual operating environment is recommended before committing to the material. As a high-performance resin, PVDF is also priced higher than most engineering plastics and general-purpose plastics.

• Limited resistance to acetone and caustic soda

• Higher cost compared to standard plastics
