PP-CF is carbon-fibre-filled polypropylene. A maker sells it for light components exposed to the elements, such as nautical equipment and mechanical automotive parts. Being semicrystalline, it carries light load well above its glass transition: its HDT at 0.45 MPa is 124–158 °C. On the H2C it prints at 240–255 °C and needs a hardened nozzle, and a maker warns that common bed adhesives will not hold polypropylene.
Partly documented Price rests on 1 product, notched Charpy impact and HDT at 0.45 MPa on 2 products each, tensile modulus (XY) and tensile strength (XY) on 3 products each and tensile strength (Z) is not published. Each figure is the median of the products that publish it comparably, and beside it the middle half of them; a value on a test bar no document describes as printed, or with no stated test load, is set apart, except a heat deflection of a plastic that cannot crystallise, which its glass transition sets, unless its document points to a moulded or resin bar.

Among the materials
Against PP-GF, PP-CF is 39 % stiffer, 36 % tougher in notched impact and 22 % weaker flat. Against PA12-CF, PP-CF is 86 % stiffer, 45 % less tough in notched impact and 37 % weaker flat. Among the materials, PP-CF has a high tensile modulus (XY) and price, and a low elongation at break (XY) and density: each is in the top or bottom quarter of the materials that publish it. The rest of its key properties sit in the middle half.

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.

What makers say about printing it
Printing advice
In order for the film/tape to not unstick, a lower bed temperature is recommended.
Nanovia PP CF, data sheet, p. 1Traditional bed adhesive solutions used for PLA and ABS (such as blue tape, glue sticks, hair spray) will not properly adhere PP to the built plate.
Braskem FL900PP-CF, data sheet, p. 1The brim is recommended to improve the adhesion of the edges and corners of the object.
Prusa Research Prusament PP Carbon Fiber by Prusa Polymers, data sheet, p. 1In the case of bed adhesion issues, it’s recommended to either use a “raft” or a polypropylene bed.
Nanovia PP CF, data sheet, p. 1The latter can be achieved by applying polypropylene film/tape to the printer bed.

Moisture sensitivity
FL900PP-CF provides engineering level performance without compromising any of PP’s inherent properties which include light weight, water resistance (no drying needed), chemical resistance, and impact resistance.
Braskem FL900PP-CF, data sheet, p. 1Low moisture absorption, typically does not require drying prior to use

Uses, limitations and chemicals
What it is sold for
Polypropylene is a semi-rigid material, with high wear and shock resistance, notably used for hinges and components that endure regular flexing.
Nanovia PP CF, data sheet, p. 1Humidity proof, it’s perfectly suited for both outdoor and high stress industral applications.
Nanovia PP CF, data sheet, p. 1Thanks to polypropylene’s close to zero water absorption rate, high chemical resistance, low density, and a native UV, Nanovia PP CF is ideal for light components exposed to the elements which require a high dimensional stability such as nautical equipment and mechanical automotive parts.
Nanovia PP CF, data sheet, p. 1
What makers warn about
Much like polyamide (nylon), polypropylene gradually becomes more flexible with higher temperatures.
Nanovia PP CF, data sheet, p. 1The product is not approved for medical applications.

| Exposure | What makers say |
|---|---|
| UV and outdoor | Described in words, with no rating, in both statements |
| Organic solvent resistance | Described in words, with no rating, in its one statement |
Makers rarely give the concentration, temperature or duration: treat them as indications, not design data. Each product's statements are on its card.
Where no maker of these products speaks to an exposure, reference data for plain PP resin is shown. Fillers, pigments and printing change it, so it does not stand for these products.

| Acid resistance | limited | Acids, bases, alcohols, detergents, lower ketones, aldehydes, water-soluble salts (class statement) (resistant), Sulfuric Acid (30%) (resistant), Sulfuric Acid (Concentrated) (not resistant), Hydrochloric Acid (Concentrated) (resistant) and Nitric Acid (40%) (not resistant) |
| Alkali resistance | limited | Sodium Hydroxide Solution (60%) (resistant) and Ammonium Hydroxide (concentrated) (limited) |
