UPVC vs. PP Copolymer
Both uPVC and PP copolymer are thermoplastics. There are 17 material properties with values for both materials. Properties with values for just one material (13, in this case) are not shown.
For each property being compared, the top bar is uPVC and the bottom bar is PP copolymer.
