PAI vs. PP Copolymer
Both PAI and PP copolymer 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 PAI and the bottom bar is PP copolymer.
