Epoxy vs. PP Copolymer
Epoxy belongs to the thermoset plastics classification, while PP copolymer belongs to the thermoplastics. There are 10 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.
For each property being compared, the top bar is epoxy and the bottom bar is PP copolymer.
