PP-B FR-V0 vs PP-B GF30
Polymer · PP-B grade comparison
PP-B FR-V0 and PP-B GF30 are two grades of the same polymer grade, PP-B: FR-V0 versus GF30 (30% coupled glass fiber). The chemistry is identical, so every difference below comes from the condition. PP-B GF30 is the stronger of the two: yield strength 24 MPa (3.48 ksi) against 20 MPa (2.9 ksi) for PP-B FR-V0, about 20% more; tensile strength follows at 70 MPa (10.2 ksi) vs 21 MPa (3.05 ksi). In exchange, PP-B FR-V0 is the more ductile: elongation 40% versus 3% for PP-B GF30, and PP-B FR-V0 is harder (70 Shore D vs 66 Shore D). PP-B GF30 is stiffer (6.2 GPa vs 1.5 GPa) and PP-B GF30 runs hotter in service (115°C vs 90°C continuous). On the shop floor, PP-B GF30 welds better (excellent vs good).
PP-B FR-V0Choose it when the part is bent, formed or impact-loaded.
PP-B GF30Choose it when strength drives the design, or when the part sees heat.
PP-B FR-V0 vs PP-B GF30: 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.
