Notes

This class implements thermal properties for polyetherimide, a high-performance thermoplastic known for its heat resistance and dimensional stability. The material is commonly used in aerospace and high-temperature applications.

Definitions

‘Thermal Conductivity’

The property of a material to conduct heat, measured in watts per meter-kelvin

‘Emissivity’

The effectiveness of a material’s surface in emitting energy as thermal radiation

‘Specific Heat’

The amount of heat required to raise the temperature of 1 kg of the material by 1 Kelvin
