Silicone Plastic vs. PTFE
Silicone plastic belongs to the thermoset plastics classification, while PTFE belongs to the thermoplastics. There are 7 material properties with values for both materials. Properties with values for just one material (20, in this case) are not shown.
For each property being compared, the top bar is silicone plastic and the bottom bar is PTFE.
