WebMay 1, 2004 · Heat transfer within a microstructured polymer optical fibre preform. Preform heating is one of the most important steps in the polymer fibre fabrication process due to the potential distortion that can be introduced when exposing the structure to high temperatures. Such heating is further complicated when internal air-structures are … 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. Wm -1 K -1.
