Extem XH1015 GF30 vs Extem XH1015 PTFE15

Polymer · Extem XH1015 grade comparison

Extem XH1015 GF30 and Extem XH1015 PTFE15 are two grades of the same polymer grade, Extem XH1015: GF30 (30% glass-fiber reinforced compound) versus PTFE15 (pTFE-lubricated bearing/wear compound). The chemistry is identical, so every difference below comes from the condition. Extem XH1015 GF30 is the stronger of the two: yield strength 115 MPa (16.7 ksi) against 90 MPa (13.1 ksi) for Extem XH1015 PTFE15, about 28% more; tensile strength follows at 170 MPa (24.7 ksi) vs 90 MPa (13.1 ksi). In exchange, Extem XH1015 PTFE15 is the more ductile: elongation 8% versus 2% for Extem XH1015 GF30. Extem XH1015 PTFE15 is lighter (1.42 g/cm³ vs 1.55 g/cm³ for Extem XH1015 GF30) and Extem XH1015 GF30 is stiffer (10 GPa vs 3.4 GPa). On the shop floor, Extem XH1015 PTFE15 machines more easily (good vs fair) and Extem XH1015 GF30 welds better (fair vs poor).

Extem XH1015 GF30Choose it when strength drives the design, or when it will be welded.

Extem XH1015 PTFE15Choose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
