PTFE vs. NEMA Laminate
PTFE belongs to the thermoplastics classification, while NEMA laminate belongs to the thermoset plastics. There are 10 material properties with values for both materials. Properties with values for just one material (12, in this case) are not shown.
For each property being compared, the top bar is PTFE and the bottom bar is NEMA laminate.
