NEMA Laminate vs. PPSU

NEMA laminate belongs to the thermoset plastics classification, while PPSU belongs to the thermoplastics. 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 NEMA laminate and the bottom bar is PPSU.
