PPE vs. NEMA Laminate
PPE belongs to the thermoplastics classification, while NEMA laminate belongs to the thermoset plastics. There are 9 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 PPE and the bottom bar is NEMA laminate.
