PTMT vs. PP Copolymer
Both PTMT and PP copolymer are thermoplastics. There are 10 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.
For each property being compared, the top bar is PTMT and the bottom bar is PP copolymer.
