PBI vs. HMWPE
PBI belongs to the thermoset plastics classification, while HMWPE belongs to the thermoplastics. There are 8 material properties with values for both materials. Properties with values for just one material (21, in this case) are not shown.
For each property being compared, the top bar is PBI and the bottom bar is HMWPE.
