PTFE vs. Silicone Plastic
PTFE belongs to the thermoplastics classification, while silicone plastic belongs to the thermoset plastics. 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 PTFE and the bottom bar is silicone plastic.
