DSG Series
THERMAL GEL MATERIALS
Thermal Gel
A liquid thermal interface material precisely dispensed into gaps through automated dispensing processes. After cure, it forms an elastic, thermally conductive gap-filling layer for thermal management in inverters, energy storage battery systems, EV charging equipment, and other new energy applications.
