PMQ Rubber vs. Soda-lime Glass

PMQ rubber and soda-lime glass belong to fundamentally different material chemistries. PMQ rubber is a polymeric material, while soda-lime glass is ceramic. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 8 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is PMQ rubber and the bottom bar is soda-lime glass.
