Definition - What does Thermostability mean?
Thermostability refers to the qualitative probability of a material to resist damage due to temperature variations or fluctuations.
Knowing the thermostability of a material facilitates the material selection process and is conducive to prolonging a given material's lifespan and resistance to corrosion.
Corrosionpedia explains Thermostability
The thermostability of a material is determined by evaluating its structural, chemical and physical response to extreme temperatures. Thermostability is determined by examining the rate of decomposition, polymerization or intergranular modifications relative to consistent rates of temperature variations.
