High-silica Glass vs. Phenolic

High-silica glass and phenolic belong to fundamentally different material chemistries. High-silica glass is a ceramic material, while phenolic is polymeric. Therefore, their performance will be even more dissimilar than would be suggested by the difference in properties. There are 8 material properties with values for both materials. Properties with values for just one material (17, in this case) are not shown.

For each property being compared, the top bar is high-silica glass and the bottom bar is phenolic.
