LCP vs. RPU
LCP belongs to the thermoplastics classification, while RPU belongs to the thermoset plastics. There are 12 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is LCP and the bottom bar is RPU.
