TPC (COPE/TPEE) FR vs TPC (COPE/TPEE) GF30
Polymer · TPC (COPE/TPEE) grade comparison
TPC (COPE/TPEE) FR and TPC (COPE/TPEE) GF30 are two grades of the same polymer grade, TPC (COPE/TPEE): FR (FR V-0) versus GF30 (30 % glass-fiber reinforced TPC). The chemistry is identical, so every difference below comes from the condition. TPC (COPE/TPEE) FR is the stronger of the two: yield strength 19 MPa (2.76 ksi) against 18 MPa (2.61 ksi) for TPC (COPE/TPEE) GF30, about 6% more. TPC (COPE/TPEE) FR is the more ductile: elongation 300% versus 8% for TPC (COPE/TPEE) GF30, and TPC (COPE/TPEE) GF30 is harder (78 Shore D vs 55 Shore D). TPC (COPE/TPEE) FR is lighter (1.32 g/cm³ vs 1.45 g/cm³ for TPC (COPE/TPEE) GF30) and TPC (COPE/TPEE) GF30 is stiffer (3.2 GPa vs 0.25 GPa).
TPC (COPE/TPEE) FRChoose it when strength drives the design, or when the part is bent, formed or impact-loaded.
TPC (COPE/TPEE) GF30Choose it when the part sees heat.
TPC (COPE/TPEE) FR vs TPC (COPE/TPEE) 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.

TPC (COPE/TPEE) FR vs TPC (COPE/TPEE) GF30 — frequently asked
Is TPC (COPE/TPEE) FR stronger than TPC (COPE/TPEE) GF30?
Yes. TPC (COPE/TPEE) FR has a typical yield strength of 19 MPa (2.76 ksi) against 18 MPa (2.61 ksi) for TPC (COPE/TPEE) GF30 — about 6% more. Tensile strength is 28 MPa (4.06 ksi) vs 68 MPa (9.86 ksi).
Which grade does FabDigit quote by default, FR or GF30?
55D is the default TPC (COPE/TPEE) condition in the FabDigit quote flow (neither FR nor GF30). 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 welds better, TPC (COPE/TPEE) FR or TPC (COPE/TPEE) GF30?
TPC (COPE/TPEE) FR. Its weldability rates very good (80/100) against very good (72/100) for TPC (COPE/TPEE) GF30.
