Soda-lime Glass vs. CAB
Soda-lime glass and CAB belong to fundamentally different material chemistries. Soda-lime glass is a ceramic material, while CAB is polymeric. 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 (21, in this case) are not shown.
For each property being compared, the top bar is soda-lime glass and the bottom bar is CAB.
