PPO GF30 vs PPO PPE-PP
Polymer · PPO grade comparison
PPO GF30 and PPO PPE-PP are two grades of the same polymer grade, PPO: GF30 (30% glass-fiber reinforced) versus PPE-PP (PPE+PP alloy). The chemistry is identical, so every difference below comes from the condition. PPO GF30 is the stronger of the two: yield strength 60 MPa (8.7 ksi) against 42 MPa (6.09 ksi) for PPO PPE-PP, about 43% more; tensile strength follows at 120 MPa (17.4 ksi) vs 42 MPa (6.09 ksi). In exchange, PPO PPE-PP is the more ductile: elongation 30% versus 3% for PPO GF30, and PPO GF30 is harder (80 Shore D vs 72 Shore D). PPO PPE-PP is lighter (1.03 g/cm³ vs 1.27 g/cm³ for PPO GF30) and PPO GF30 is stiffer (8.3 GPa vs 1.9 GPa). On the shop floor, PPO PPE-PP machines more easily (good vs fair).
PPO GF30Choose it when strength drives the design, or when the part sees heat.
PPO PPE-PPChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.
PPO GF30 vs PPO PPE-PP: 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.

PPO GF30 vs PPO PPE-PP — frequently asked
Is PPO GF30 stronger than PPO PPE-PP?
Yes. PPO GF30 has a typical yield strength of 60 MPa (8.7 ksi) against 42 MPa (6.09 ksi) for PPO PPE-PP — about 43% more. Tensile strength is 120 MPa (17.4 ksi) vs 42 MPa (6.09 ksi).
Which grade does FabDigit quote by default, GF30 or PPE-PP?
UNF is the default PPO condition in the FabDigit quote flow (neither GF30 nor PPE-PP). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.
Which is easier to machine, PPO GF30 or PPO PPE-PP?
PPO PPE-PP. Its machinability rates good (68/100) against fair (48/100) for PPO GF30; for welding the order is PPO GF30 first (very good, 70/100) then PPO PPE-PP (good, 65/100).
