PPSU vs. NEMA Laminate

PPSU belongs to the thermoplastics classification, while NEMA laminate belongs to the thermoset plastics. There are 13 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.

For each property being compared, the top bar is PPSU and the bottom bar is NEMA laminate.
