TPC (COPE/TPEE) ESD vs TPC (COPE/TPEE) GF30

Polymer · TPC (COPE/TPEE) grade comparison

TPC (COPE/TPEE) ESD and TPC (COPE/TPEE) GF30 are two grades of the same polymer grade, TPC (COPE/TPEE): ESD (antistatic / conductive TPC compound) versus GF30 (30 % glass-fiber reinforced TPC). The chemistry is identical, so every difference below comes from the condition. TPC (COPE/TPEE) ESD is the stronger of the two: yield strength 20 MPa (2.9 ksi) against 18 MPa (2.61 ksi) for TPC (COPE/TPEE) GF30, about 11% more. TPC (COPE/TPEE) ESD is the more ductile: elongation 250% versus 8% for TPC (COPE/TPEE) GF30, and TPC (COPE/TPEE) GF30 is harder (78 Shore D vs 58 Shore D). TPC (COPE/TPEE) ESD is lighter (1.24 g/cm³ vs 1.45 g/cm³ for TPC (COPE/TPEE) GF30) and TPC (COPE/TPEE) GF30 is stiffer (3.2 GPa vs 0.3 GPa).
