PAR vs. NEMA Laminate
PAR belongs to the thermoplastics classification, while NEMA laminate belongs to the thermoset plastics. There are 11 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.
For each property being compared, the top bar is PAR and the bottom bar is NEMA laminate.
