Best for
- Tower packing for distillation and scrubbing columns
- Mist eliminators
It also suits:
- Fixtures, trays and guards around hot acid baths
Not the right choice for
- Hot structural parts
- Strong bases (pH 12 and above), amines, or polar solvents such as acetone and ethyl acetate
Key properties
| Tensile strength | 40 to 51 MPa |
|---|---|
| Heat deflection | 158 C at 0.45 MPa |
| Flammability | UL94 V-0 at 1.5 mm |
What to use instead
- PEEK when the part needs real load-bearing strength at high heat rather than chemical resistance, in the carbon-filled grade.
- PPS when the exposure is fuels or solvents rather than strong acids or chlorine, and the part also needs to run hot.
- ASA when the chemical and UV exposure turns out to be mild after all.
- Polypropylene (PP) when the chemical is caustic soda or acetone, which attack PVDF.
The FDM material selector narrows the whole range by operating temperature, load, chemical exposure, and budget.
