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

Polymer · TPC (COPE/TPEE) grade comparison

TPC (COPE/TPEE) BIO and TPC (COPE/TPEE) GF30 are two grades of the same polymer grade, TPC (COPE/TPEE): BIO (partially bio-based TPC) versus GF30 (30 % glass-fiber reinforced TPC). The chemistry is identical, so every difference below comes from the condition. TPC (COPE/TPEE) GF30 is the stronger of the two: yield strength 18 MPa (2.61 ksi) against 15 MPa (2.18 ksi) for TPC (COPE/TPEE) BIO, about 20% more; tensile strength follows at 68 MPa (9.86 ksi) vs 36 MPa (5.22 ksi). In exchange, TPC (COPE/TPEE) BIO is the more ductile: elongation 500% versus 8% for TPC (COPE/TPEE) GF30, and TPC (COPE/TPEE) GF30 is harder (78 Shore D vs 50 Shore D). TPC (COPE/TPEE) BIO is lighter (1.2 g/cm³ vs 1.45 g/cm³ for TPC (COPE/TPEE) GF30) and TPC (COPE/TPEE) GF30 is stiffer (3.2 GPa vs 0.15 GPa). On the shop floor, TPC (COPE/TPEE) BIO welds better (excellent vs very good).

TPC (COPE/TPEE) BIOChoose it when the part is bent, formed or impact-loaded, or when weight is the constraint.

TPC (COPE/TPEE) GF30Choose it when strength drives the design, or when the part sees heat.
