DAP vs. Silicone Plastic
Both DAP and silicone plastic are thermoset plastics. There are 15 material properties with values for both materials. Properties with values for just one material (7, in this case) are not shown.
For each property being compared, the top bar is DAP and the bottom bar is silicone plastic.
