Latest company case about Q: What is the significance of the glass transition temperature (Tg) of potting compounds?

Answer: Tg is the temperature at which the material changes from glass state to high elastic state. Above Tg, the material becomes soft, the modulus drops sharply, and CTE changes. For products with high operating temperature, potting compounds with Tg higher than the highest operating temperature should be selected.
