Compare PMMA to Soda-lime Glass

PMMA and soda-lime glass belong to fundamentally different material chemistries. PMMA 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 11 material properties with values for both materials. Properties with values for just one material (14, in this case) are not shown.
