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