PU-FR-V0 vs PU-PC-like

Polyurethane · grade comparison

PU-FR-V0 and PU-PC-like are both polyurethane grades. PU-PC-like is the stronger of the two: tensile strength 60 MPa (8.7 ksi) against 48 MPa (6.96 ksi) for PU-FR-V0, about 25% more. PU-PC-like is the more ductile: elongation 12% versus 6% for PU-FR-V0. PU-PC-like is lighter (1.13 g/cm³ vs 1.6 g/cm³ for PU-FR-V0) and PU-FR-V0 is stiffer (2.6 GPa vs 2.2 GPa).

PU-FR-V0Choose it when the part sees heat.

PU-PC-likeChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

PU-FR-V0 vs PU-PC-like — frequently asked

Is PU-PC-like stronger than PU-FR-V0?

Yes. PU-PC-like has a typical tensile strength of 60 MPa (8.7 ksi) against 48 MPa (6.96 ksi) for PU-FR-V0 — about 25% more.

Which is cheaper, PU-FR-V0 or PU-PC-like?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

When should I choose PU-FR-V0 over PU-PC-like?

Pick PU-FR-V0 when the part sees heat. Pick PU-PC-like when strength drives the design, or when the part is bent, formed or impact-loaded.
