ABS vs PESU-GF30

Polymer · grade comparison

ABS and PESU-GF30 are both polymer grades. PESU-GF30 is the stronger of the two: tensile strength 150 MPa (21.8 ksi) against 43 MPa (6.24 ksi) for ABS, about 3.5 times as much. In exchange, ABS is the more ductile: elongation 25% versus 2.5% for PESU-GF30, and PESU-GF30 is harder (90 Shore D vs 78 Shore D). ABS is lighter (1.04 g/cm³ vs 1.6 g/cm³ for PESU-GF30) and PESU-GF30 is stiffer (9.5 GPa vs 2.3 GPa). On the shop floor, ABS machines more easily (very good vs fair), ABS welds better (very good vs fair), and ABS sits in a lower cost tier (budget, $) than PESU-GF30 (high, $$$$).

ABSChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

PESU-GF30Choose it when strength drives the design, or when the part sees heat.

ABS vs PESU-GF30 — frequently asked

Is PESU-GF30 stronger than ABS?

Yes. PESU-GF30 has a typical tensile strength of 150 MPa (21.8 ksi) against 43 MPa (6.24 ksi) for ABS — about 3.5 times as much.

Which is cheaper, ABS or PESU-GF30?

ABS is the lower-cost material: it sits in the budget tier ($) while PESU-GF30 is high ($$$$). 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, ABS or PESU-GF30?

ABS. Its machinability rates very good (80/100) against fair (45/100) for PESU-GF30; for welding the order is ABS first (very good, 78/100) then PESU-GF30 (fair, 50/100).
