Materials / Data sheet

Carbon-fiber PPS PPS-CF

Hot zones and chemicals. The maker rates it flame-retardant and self-extinguishing, so it is what we use near electrics.

In plain words

Good for

Hot zones and chemicals. The maker rates it flame-retardant and self-extinguishing, so it is what we use near electrics.

Not for

Parts that take sharp hits across the layers: it is stiff and brittle when loaded upright.

Upright is weaker

A printed part is strongest along its layers (flat, X-Y) and weaker across them (upright, Z). The table shows both. We turn the part so the load runs along the layers.

Test conditions from the data sheet: not stated dry/conditioned; specimens X1E, chamber 60 °C, not annealed. These are lab numbers for test bars, not a working limit for your part. The real limit depends on the load, the time at temperature and the shape, which is why we ask about all three.
