PP GF10 vs PP GF30

Polymer · grade comparison

PP GF10 and PP-GF30 are both polymer grades, compared here in the GF10 condition. PP-GF30 is the stronger of the two: yield strength 85 MPa (12.3 ksi) against 33 MPa (4.79 ksi) for PP GF10, about 158% more; tensile strength follows at 85 MPa (12.3 ksi) vs 45 MPa (6.53 ksi). In exchange, PP GF10 is the more ductile: elongation 6% versus 3% for PP-GF30, and PP-GF30 is harder (80 Shore D vs 72 Shore D). PP GF10 is lighter (0.97 g/cm³ vs 1.13 g/cm³ for PP-GF30) and PP-GF30 is stiffer (6 GPa vs 2.8 GPa). On the shop floor, PP GF10 machines more easily (good vs fair), PP GF10 welds better (excellent vs fair), and PP GF10 sits in a lower cost tier (budget, $) than PP-GF30 (standard, $$).

PP GF10Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

PP-GF30Choose it when strength drives the design.
