MXD6 GF-FR-V0 vs MXD6 GF30

Polymer · MXD6 grade comparison

MXD6 GF-FR-V0 and MXD6 GF30 are two grades of the same polymer grade, MXD6: GF-FR-V0 (GF + flame retardant, UL 94 V-0) versus GF30 (30% glass-fiber reinforced injection grade). The chemistry is identical, so every difference below comes from the condition. MXD6 GF30 is the stronger of the two: tensile strength 200 MPa (29 ksi) against 165 MPa (23.9 ksi) for MXD6 GF-FR-V0, about 21% more. MXD6 GF30 is the more ductile: elongation 2.5% versus 2% for MXD6 GF-FR-V0. MXD6 GF30 is lighter (1.48 g/cm³ vs 1.62 g/cm³ for MXD6 GF-FR-V0). On the shop floor, MXD6 GF30 welds better (good vs fair).
