I have listed below properties values of PTRALUX flexible composites. The numbers should be considered as numbers for setting specifications. The values represent all products (coverlay, bond ply, sheet adhesive, and clads) after cure. The clads have Cu removed.
Youngs Modulus
Cured adhesive only 85000 psi 6E4 kPa
Coverlay, bond ply, clad 150000-30000 psi 1E6-2E6
Poisons Ratio
Adhesive only 200-300%
Coverlay, bond ply, clad 50
I hope this helps.
Best Regards,
