Does Silicone Have Thermal Conductivity?
Thermal conductivity refers to the efficiency with which a material can conduct heat. A material that conducts a lot of heat can absorb heat, transfer the heat across itself, and give off heat easily. This is often done with a high degree of consistency. Heat-conductive materials are often used when we want to control or facilitate the …
