PP Copolymer vs. PAI
Both PP copolymer and PAI are thermoplastics. There are 13 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 PP copolymer and the bottom bar is PAI.
