PVDF is polyvinylidene fluoride, a semicrystalline polymer that carries light load well above its glass transition. Makers sell it for electrical and electronic equipment and demanding applications, citing resistance to most chemicals and solvents, and a maker does not recommend food contact. On the H2C it prints at 250–265 °C, and a maker recommends a heated chamber but says no drying is needed.
Thinly documented Three products, with values from three makers' documents: 3DXTECH's, Fillamentum's and Filament2Print's. Read each figure as a few sheets' word.

Among the materials
Among the materials, PVDF has a high elongation at break (XY), HDT at 0.45 MPa, density and price: each is in the top quarter of the materials that publish it. Its tensile modulus (XY) and tensile strength (XY) sit in the middle half.
Against its alternatives, PVDF has the highest HDT at 0.45 MPa and price
How does it compare with what an engineer would buy instead?
- PVDF: its products' median and middle half
- an alternative
- lowest to highest
- each material's median (top row)
- beyond the scale
Each row is a material, each column a property: the bar is the middle half of a material's products, the tick their median, the hairline their lowest to highest; the ticks above the rows are every material's median.

Mechanical properties
Printed flat (XY), PVDF typically reaches a tensile strength of 51 MPa at a modulus of 2.45 GPa, and breaks at 25 % elongation. In bending, its flexural strength is typically 50 MPa at a flexural modulus of 1.8 GPa.

Thermal properties
Its products put HDT at 158 °C under 0.45 MPa, against a glass transition of -34 °C. Semicrystalline, it carries light load well above its glass transition. As published, melting is 170 °C, from one product.

Printing on the H2C
PVDF prints within the H2C's limits and softens near 158 °C, above its 65 °C chamber
What does printing it on the H2C take, and how hot can a part get?
- share of the products that accept each temperature
- one end given ("at least")
- the H2C's limit, and beyond it
- a product
- PVDF: its products' median and middle half
- as published, under each sheet's own test

One temperature axis for the settings a print needs and the temperatures a part meets. A setting's shade is how many of the products whose sheets give a window accept each degree; the H2C's limit closes its row.
