MDPE vs. Thermoplastic PI
Both MDPE and thermoplastic PI are thermoplastics. There are 6 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
For each property being compared, the top bar is MDPE and the bottom bar is thermoplastic PI.
