PC vs. Borosilicate Glass
PC and borosilicate glass belong to fundamentally different material chemistries. PC is a polymeric material, while borosilicate glass is ceramic. 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 (28, in this case) are not shown.
For each property being compared, the top bar is PC and the bottom bar is borosilicate glass.
