PP Copolymer vs. PMMA
Both PP copolymer and PMMA are thermoplastics. There are 14 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.
For each property being compared, the top bar is PP copolymer and the bottom bar is PMMA.
