PAS GF10 vs PAS GF30

Polymer · PAS grade comparison

PAS GF10 and PAS GF30 are two grades of the same polymer grade, PAS: GF10 (10 % glass-fibre reinforced) versus GF30 (30 % glass-fibre reinforced). The chemistry is identical, so every difference below comes from the condition. PAS GF30 is the stronger of the two: yield strength 140 MPa (20.3 ksi) against 75 MPa (10.9 ksi) for PAS GF10, about 87% more; tensile strength follows at 140 MPa (20.3 ksi) vs 92 MPa (13.3 ksi). In exchange, PAS GF10 is the more ductile: elongation 6% versus 2.5% for PAS GF30. PAS GF10 is lighter (1.36 g/cm³ vs 1.51 g/cm³ for PAS GF30) and PAS GF30 is stiffer (9 GPa vs 4 GPa). On the shop floor, PAS GF10 machines more easily (good vs fair).

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

PAS GF30Choose it when strength drives the design.
