Silicone Plastic vs. CR Rubber
Silicone plastic belongs to the thermoset plastics classification, while CR rubber belongs to the thermoset elastomers (rubber). There are 9 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is silicone plastic and the bottom bar is CR rubber.
