Is silicone a good thermal conductor?
Explanation with a diagram:
Silicon has poor thermal conductivity. Compared to other materials, silicone transfers heat very slowly. Due to its stable structure, silicone has high heat resistance.
Silicone: Silicone, also known as polysiloxane, is a type of polymer, this class of polymers includes any inert, synthetic compound composed of repeating units of siloxane, It is an alternating chain of oxygen and silicon atoms often combined with hydrogen and carbon.
Diagram:
Hence, silicone is a poor thermal conductor.
