High insulating properties
Web28 de jul. de 2024 · Consequently, a high energy density of 11.3 J/cm 3 is obtained concurrently. In addition, numerical simulations including finite element methods and phase field calculations are calculated to explain the facilitation of insulating properties. WebThe thermal insulating capacity of plastics is rated by measuring the thermal conductivity. Thermal conduction is the transfer of heat from one part of a body to another with which it is in contact. For amorphous plastics at 0-200°C, the thermal conductivity lies between 0.125-0.2.
