PPSU vs. Hardwood
PPSU belongs to the thermoplastics classification, while hardwood belongs to the wood-based materials. There are 15 material properties with values for both materials. Properties with values for just one material (19, in this case) are not shown.
For each property being compared, the top bar is PPSU and the bottom bar is hardwood.
