HFC high-frequency thermal electromagnetic wave absorption sheet H300MAS is a kind of dual-function composite material that combines thermal management and electromagnetic wave absorption functions. It not only has good elasticity and compressibility, but also has strong surface viscosity and excellent operation, applied between integrated circuits, heat sinks, other heatconducting components and metal substrates, in addition to solving the problem of heat conduction in materials, it can also suppress unnecessary electromagnetic energy coupling, resonance and EMI problems caused by electromagnetic interference. In the era of high-frequency transmission ,the product has broad application prospects.
FEATURES:
●Double advantages of electromagnetic wave absorption and heat conduction
● Low thermal resistance
● Good surface compatibility and self-adhesive
● High fire resistance
● Application under low pressure
● Excellent electrical insulation performance
