Borosilicate Glass vs. ECO Rubber
Borosilicate glass and ECO rubber belong to fundamentally different material chemistries. Borosilicate glass is a ceramic material, while ECO rubber 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 (19, in this case) are not shown.
For each property being compared, the top bar is borosilicate glass and the bottom bar is ECO rubber.
