Parker Chomerics THERM-A-GAP® GEL 75 is a high-performance, one-component, fully cured dispensable thermal interface gel with an advanced thermal conductivity of 7.5 W/m-K. Its paste-like consistency allows controlled dispensing in variable thicknesses, while requiring minimal compressive force to conform, reducing mechanical stress on components and solder joints. The material is reworkable, requires no secondary curing, and is optimized for automated dispensing and field repair. With excellent thermal management and reliability, it is designed for next-generation, high-power electronic systems.
Telecommunications base stations.
Power supplies and semiconductor devices.
Memory and power modules.
Microprocessors and central processing units (CPUs).
Advanced electronics requiring low thermal impedance and reliable heat dissipation.
