The series includes four highly reliable silicone-based greases offering thermal conductivity of 1.5 W/mK (THERM-A-GREASE™ 15), 3.0 W/mK (THERM-A-GREASE™ 30), 5.0 W/mK (THERM-A-GREASE™ 50), and 7.0 W/mK (THERM-A-GREASE™ 70), providing efficient heat dissipation in a wide range of electronic applications. The minimum bond line of 0.025 mm ensures the products are suitable for applications with tight manufacturing and assembly tolerances.
 
THERM-A-GREASE™ operates efficiently at low pressure, enabling heat transfer tasks involving delicate or densely packed printed circuit board (PCB) components. To further enhance performance and reliability, THERM-A-GREASE™ 15 and THERM-A-GREASE™ 30 feature a low thermal impedance of 0.097 °C-cm²/W at 2.75 bar and 0.084 °C-cm²/W at 6.89 bar (with a minimum bond line thickness of 0.025 mm). For applications requiring an even better conductor, THERM-A-GREASE™ 50 offers a thermal impedance of 0.084 °C-cm²/W at 2.75 bar and 0.071 °C-cm²/W at 6.89 bar. For the lowest thermal impedance, THERM-A-GREASE™ 70 offers 0.065 °C-cm²/W at 2.75 bar and 0.045 °C-cm²/W at 6.89 bar.

All figures meet the ASTM D5470 test method. The new thermal greases require only low compressive force and deform easily under assembly pressure to minimize stress on components, soldered joints, and PCB leads. This flexibility ensures user convenience by allowing easy application of THERM-A-GREASE™ via stenciling, screen printing, or dispensing. The absence of any mixing, curing, or cooling requirements simplifies both application and storage, while reuse for repair tasks is also straightforward.
 
Thanks to a rigorous testing regime, THERM-A-GREASE™ offers exceptionally reliable thermal management even in the most extreme environments. The products withstand thermal cycling, long-term thermal aging, and high humidity conditions, providing stability without pumping or hardening/cracking over time. These attributes make them suitable for applications ranging from CPUs, GPUs, and memory modules in the computer industry to power supplies, power conversion equipment, lighting, and automotive control modules. Key electrical properties include a dielectric constant of 7.0 at 1000 kHz (ASTM D150 test method) and a dissipation factor of 0.002 at 1000 kHz (Chomerics test method). The entire THERM-A-GREASE™ series is available in a range of packaging options, including a manual syringe, EFD plastic cartridge, 8-ounce bottle, and aluminum cartridge. Fill volumes are available up to 300 cc.
