A fluoropolymer with outstanding chemical and UV resistance at 1.71 g/cm³ and $251/kg. The only material in the dataset with a genuinely severe fume hazard: above 315 °C it releases hydrofluoric acid and hydrogen cyanide, and local exhaust is mandatory.
Applications
PVDF is used for chemical-process piping, tubing, pumps, tanks, filters and valves because chemical resistance is often the deciding requirement. Arkema describes Kynar PVDF in systems exposed to acids and chlorinated or brominated chemicals, including process equipment that also undergoes chemical or steam cleaning. Selected grades can be injection molded or extruded into smooth fluid-contact surfaces, then welded into larger assemblies.
Chemical resistance is its main advantage over less resistant plastics and, in some systems, costly corrosion-resistant metals. Select the grade against the actual fluid, concentration and temperature: several organic solvents swell or dissolve PVDF, and strong alkalis can attack it. Fluid-contact prints also need attention to porosity, welds, joints and residual stress; a manufactured piping system's pressure or purity rating does not transfer to an FDM component.

Health & safety4 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Fume toxicity (1–5) | Very high — toxic decomposition products; local exhaust mandatory. Above 315 °C thermal decomposition yields hydrofluoric acid, hydrogen cyanide and carbon monoxide | 1 source
|
| Hazardous species emitted | Above 315 °C: hydrofluoric acid, hydrogen cyanide, phenols, carbon monoxide, carbon dioxide and dense smoke. HF is extremely corrosive, its skin burns may not be immediately visible or painful, and exposure can be fatal by skin absorption, inhalation or ingestion | 1 source
|
| Ventilation / filtration requirement (1–5) | Local exhaust to outside / fume hood — the SDS states local exhaust is preferred | 1 source
|
| Dust & fibre handling hazard | Molten polymer causes thermal burns and must not be pulled off the skin. If HF is detected during a decomposition event, cut the heat but keep the extraction running, ventilate, and clear non-essential people from the area | 1 source
|
Finishing & post-processing1 field
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|
| Dimensional accuracy & detail | The processing window sits well below the 315 °C decomposition threshold, so nozzle temperature must be controlled rather than raised to chase flow | 2 sources

How to read these values
Values describe representative grades, not every spool. Manufacturer datasheets and independent tests retain their source labels and dates. Printed orientation, test method, conditioning and formulation can change results. Unknown values are —. A listed use is not a certification. Shore A, Shore D and Rockwell hardness are separate scales.
