Bamboo Plywood vs. PEI
Bamboo plywood belongs to the wood-based materials classification, while PEI belongs to the thermoplastics. There are 15 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 bamboo plywood and the bottom bar is PEI.
