Appendix B.2. Cyclic Olefin Copolymer
Values for the density (ρCOC = 1020 kg m−3), specific heat (cCOC, see Table A2), and thermal conductivity (κCOC,23°C = 0.17 W m−1 K−1 and κCOC,320°C = 0.24 W m−1 K−1, linear fit in between these point) of TOPAS 6017 COC are obtained via TOPAS Advanced Polymers (TOPAS Advanced Polymers, Farmington Hills, MI, USA). The heat capacity at constant pressure (CP,COC) is calculated assuming a homogeneous body of mass m, via Equation (A5), where COMSOL interpolated linearly in between the points. (A5) CP,COC=cCOC×m
