PSU-GF30 GF30 vs PSU-GF30 GF30-BK-UV
Polymer · PSU-GF30 grade comparison
PSU-GF30 GF30 and PSU-GF30 GF30-BK-UV are two grades of the same polymer grade, PSU-GF30: GF30 (30% glass-fiber reinforced injection molding grade) versus GF30-BK-UV (GF30 black, UV / weather stabilized). The chemistry is identical, so every difference below comes from the condition. On the shop floor, PSU-GF30 GF30 welds better (fair vs poor).

PSU-GF30 GF30 vs PSU-GF30 GF30-BK-UV: propertiesHow to read these bars
- One bar per material. A full bar is the highest value among all polymer grades in the FabDigit library; each bar is drawn as a share of that.
- The better value (by the usual engineering direction) is in bold. Rows with no direction — density, thermal conductivity — have no bold.
- Values are typical room-temperature figures for the condition named on each card.
- Confirm against the certified mill or resin datasheet before design release.
