Phenolic vs. UPVC
Phenolic belongs to the thermoset plastics classification, while uPVC belongs to the thermoplastics. There are 20 material properties with values for both materials. Properties with values for just one material (11, in this case) are not shown.
For each property being compared, the top bar is phenolic and the bottom bar is uPVC.
