Thermoset PI vs. UHMW-PE
Thermoset PI belongs to the thermoset plastics classification, while UHMW-PE belongs to the thermoplastics. There are 9 material properties with values for both materials. Properties with values for just one material (24, in this case) are not shown.
For each property being compared, the top bar is thermoset PI and the bottom bar is UHMW-PE.
