PVC-P vs. Silicone Plastic
PVC-P belongs to the thermoplastics classification, while silicone plastic belongs to the thermoset plastics. There are 16 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 PVC-P and the bottom bar is silicone plastic.
