Insulating material refers to a material that has low thermal conductivity and high electrical resistance. Some synonyms for insulating material include insulation, thermal insulation, electrical insulation, insulator, and dielectric. Insulation is a more general term that refers to any material used to maintain temperature or protect against electrical currents. Thermal insulation specifically refers to materials used to prevent heat transfer, while electrical insulation refers to materials that prevent the flow of electricity through a circuit. An insulator is a material that resists electrical conductivity, and a dielectric specifically refers to materials that prevent current flow in capacitors. These terms are often used interchangeably and can vary based on context.
