PEEK vs. NEMA Laminate
PEEK belongs to the thermoplastics classification, while NEMA laminate belongs to the thermoset plastics. There are 12 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 PEEK and the bottom bar is NEMA laminate.
