Huntsman Advanced Materials has developed a wide portfolio of casting and impregnation resins for EV applications. The Tg can act as a very powerful (and also misleading) physical quantity to describe those epoxy and polyurethane resins.

We will present the basic principles of the Tg and its relation to material properties below and above the Tg. For instance, the more flexible thermoset network above Tg directly impacts absorption of oil and water.

For our product range of epoxy and polyurethane resins, the Tg start at -60°C and can be as high as 200°C. This allows us to define 3 groups of materials:

1. Tg below the minimum operating temperature: Tg_MIN
2. Tg within the operating temperature: Tg_MID
3. Tg above the maximum operating temperature: Tg_MAX

For each group of material, we will give examples of typical EV applications and suitable products and production processes:

1. Tg_MIN casting resins for battery applications
2. Tg_MID potting and impregnation resins for stators and electronics
3. Tg_MAX potting and impregnation resins rotating parts like rotors
