class Polyetherimide(Solid):
"""
A class representing polyetherimide (PEI) material properties, commonly used in reservoir casings
and other high-temperature thermoplastic applications.
Attributes
----------
conductivity : float
Thermal conductivity in W/(m·K) (0.2)
emissivity : float
Surface emissivity, unitless (0.96)
specific_heat : float
Specific heat capacity in J/(kg·K) (1100)
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
