Introduction
In modern industrial environments, managing heat has become one of the most critical engineering challenges. Whether the application involves power electronics, automotive systems, laser modules, 5G communication devices, industrial automation equipment, or high-load computing hardware, heat buildup can cause catastrophic failure. Overheating reduces component lifespan, lowers performance stability, and increases the risk of shutdowns. This is where high temperature thermal grease becomes indispensable.
As a leading supplier in the thermal-management materials market, Dubang focuses on providing durable, stable, and high-efficiency high temperature thermal grease solutions for B2B clients. This guide covers the functions, characteristics, application scenarios, selection criteria, and performance evaluation standards of high-temperature thermal grease—helping engineers and procurement teams make well-informed decisions.
Understanding High Temperature Thermal Grease
What Is High Temperature Thermal Grease?
High temperature thermal grease is a thermal interface material engineered to remain stable under elevated temperatures while providing efficient heat transfer between components. Unlike regular thermal paste, it maintains consistency and thermal conductivity even under extreme heat cycles or continuous high-temperature operation.
The material typically contains silicone oil or synthetic oil combined with thermally conductive fillers such as aluminum oxide, zinc oxide, boron nitride, graphite, or ceramic-metal composites. The purpose is to fill microscopic air gaps between heat-generating components and cooling interfaces.
Why High Temperature Grease Matters in Industrial Environments
In power grids, industrial IoT devices, aerospace electronics, heavy-duty LED systems, EV charging modules, and factory robotics, temperatures frequently reach 150°C to 200°C or more. Standard thermal paste dries, cracks, or fails under such conditions. High temperature thermal grease remains stable, making it essential for equipment longevity and reliability.
Key Technical Characteristics of High Temperature Thermal Grease
Thermal Conductivity
Thermal conductivity determines how much heat can be transferred through the grease. Dubang’s formulations range from 1 W/m·K to over 12 W/m·K, ensuring suitable performance across various industrial needs.
Thermal Stability and Operating Temperature Range
High temperature thermal grease must endure harsh temperature conditions. Dubang’s formulations can support continuous operation up to 200–250°C, with peak resistance up to 300°C depending on the product type.
Pump-Out Resistance
Pump-out occurs when thermal cycling forces the grease out of the interface. Dubang designs high temperature thermal grease with superior mechanical stability to resist pump-out even under vibration and stress.
Dielectric Strength
In many electronic applications, insulation is critical. Dubang’s thermal greases provide strong dielectric protection to prevent electrical leakage.
Viscosity and Spreadability
Viscosity affects application ease, consistency, and long-term stability. Proper viscosity ensures that thermal grease does not migrate over time and maintains consistent thermal contact.
Industrial Applications of High Temperature Thermal Grease
Power Electronics
Devices including IGBT, MOSFET, SCR, and power modules generate significant heat. High temperature thermal grease ensures efficient and stable heat transfer in applications such as:
-
Inverters
-
Power supplies
