Asahi kasei duraflex™: Low Viscosity Curing Agent Enhances Thermal Management Material Performance
Thermal issues, industry consensus
The rapid development of new energy vehicles, 5G communication devices, and AI servers has driven the miniaturization and high integration of electronic components.The resulting heat generation issue has become a core challenge restricting performance and lifespan.
Especially inGap filler thermal materialThe demand for high thermal conductivity in applications continues to increase, but the contradiction of "high filler leads to high viscosity and processing difficulties" always exists.How to maintain good fluidity while improving thermal conductivity.It has become a key issue in the thermal material industry.
01Core Advantages
Meeting multiple requirements of thermal conductivity, process compatibility, stability and reliability, and global compliance.
1High thermal conductivity efficiency"—— Relies on high loading of thermally conductive fillers, but can lead to an increase in system viscosity."
2Process Compatibility- Narrow components and complex structures place higher demands on material flowability.
3Long-term reliabilityThe material needs to have good flexibility to withstand vibration and thermal cycling.
Industry competition is gradually shifting from "Single thermal conductivity"towards"Comprehensive AdaptabilityEvolution.
