TPU-Ester vs TPV

Polymer · grade comparison

TPU-Ester and TPV are both polymer grades. TPU-Ester is the stronger of the two: tensile strength 45 MPa (6.53 ksi) against 8 MPa (1.22 ksi) for TPV, about 5.4 times as much. TPU-Ester is the more ductile: elongation 500% versus 450% for TPV, and TPU-Ester is harder (40 Shore D vs 24 Shore D). TPV is lighter (0.97 g/cm³ vs 1.22 g/cm³ for TPU-Ester) and TPU-Ester is stiffer (0.05 GPa vs 0.02 GPa). On the shop floor, TPU-Ester machines more easily (fair vs poor), TPU-Ester welds better (excellent vs very good), and TPU-Ester sits in a lower cost tier (standard, $$) than TPV (premium, $$$).

TPU-EsterChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.

TPVChoose it when weight is the constraint, or when the part sees heat.

TPU-Ester vs TPV — frequently asked

Is TPU-Ester stronger than TPV?

Yes. TPU-Ester has a typical tensile strength of 45 MPa (6.53 ksi) against 8 MPa (1.22 ksi) for TPV — about 5.4 times as much.

Which is cheaper, TPU-Ester or TPV?

TPU-Ester is the lower-cost material: it sits in the standard tier ($$) while TPV is premium ($$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, TPU-Ester or TPV?

TPU-Ester. Its machinability rates fair (35/100) against poor (25/100) for TPV; for welding the order is TPU-Ester first (excellent, 85/100) then TPV (very good, 75/100).
