PPO vs. NEMA Laminate
PPO 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 (10, in this case) are not shown.
For each property being compared, the top bar is PPO and the bottom bar is NEMA laminate.
