UF vs. PAS
UF belongs to the thermoset plastics classification, while PAS belongs to the thermoplastics. There are 12 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is UF and the bottom bar is PAS.
