Soda-lime Glass vs. NEMA Laminate

Soda-lime glass and NEMA laminate belong to fundamentally different material chemistries. Soda-lime glass is a ceramic material, while NEMA laminate is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 7 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.

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