PES vs. UF

PES belongs to the thermoplastics classification, while UF belongs to the thermoset plastics. There are 15 material properties with values for both materials. Properties with values for just one material (16, in this case) are not shown.

For each property being compared, the top bar is PES and the bottom bar is UF.
