ECO Rubber vs. PBI
ECO rubber belongs to the thermoset elastomers (rubber) classification, while PBI belongs to the thermoset plastics. There are 11 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 ECO rubber and the bottom bar is PBI.
