PBI vs. NEMA Laminate
Both PBI and NEMA laminate are thermoset plastics. There are 12 material properties with values for both materials. Properties with values for just one material (18, in this case) are not shown.
For each property being compared, the top bar is PBI and the bottom bar is NEMA laminate.
