2000Mesh 2500Mesh Green silicon carbide micro powder for radiator coating of new energy vehicles
- Ultra-High Thermal Conductivity: With a theoretical thermal conductivity far exceeding alumina, SiC micro powder transforms protective coatings into active heat-dissipation layers, significantly reducing interfacial thermal resistance.
- Superior Electrical Insulation: Engineered SiC micro powder provides the critical dielectric strength required for EV battery cooling systems and electronic control units, ensuring safety alongside cooling.
- Low Coefficient of Thermal Expansion (CTE): Its minimal CTE ensures excellent adhesion and prevents coating delamination or cracking during extreme thermal cycling—a must for long-term vehicle reliability.
- Extreme Hardness and Corrosion Resistance: Boasting a Mohs hardness of 9.5, it provides a robust shield against stone chipping, road salt, and environmental corrosion, extending the service life of aluminum radiator cores.
