Carbon-fibre polypropylene: HDT jumps to 158 °C at 0.45 MPa while density stays at 0.91 g/cm³, the best stiffness-to-weight in the dataset. Prusa states a hardened nozzle is necessary.
Applications
PP-CF is useful where chemical resistance and low moisture uptake matter as much as mechanical shape: laboratory supports, chemical-container fittings and lightweight equipment components. Prusa shows vial stands, canister lids and a pool-chlorine dispenser in its introduction to Prusament PP Carbon Fiber. The PP matrix supplies resistance to particular chemicals, while the carbon filler improves printing stability and changes the part from a bendable polypropylene toward a more rigid composite.
That change brings a cost: Prusa explicitly describes reduced layer adhesion and greater fragility than pure PP. Do not choose it for a living hinge just because the matrix is polypropylene. Chemical compatibility must also include concentration and temperature; the manufacturer's table shows that some solvents attack or strongly permeate it. A printed container example establishes a build, not a pressure or leak-tightness rating.
Vial stands and chemical-container fittings ↗
FDM · Prusament PP Carbon Fiber Black · Manufacturer-listed applications
Prusa presents printed vial stands, a canister lid and a chlorine dispenser as examples of its PP-CF. They illustrate chemical-contact hardware; the article's exhaust-manifold model is explicitly a visual model, not a working exhaust component.

Health & safety3 fields
| Property and unit | Published value and conditions | Sources and dates |
|---|---|---|

| Softened or crazed by | Xylene, decalin, CCl4 and chlorobenzene are heavily absorbed at 20 °C; oleum, chlorosulphonic acid and bromine destroy it. | 1 source |
| Solvent welding & smoothing agent | None — nothing softens PP at room temperature, so joints have to be welded thermally rather than chemically. | 1 source |
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.
