Thermal Conductive Wave Absorber

Fehonda® Thermal Conductive Wave Absorber Series

Fehonda® Thermal Conductive Wave Absorber Series is engineered to deliver dual functionality — efficient heat dissipation and electromagnetic wave absorption (EMI/RF suppression) — within a single advanced material system.
This next-generation solution combines thermal conductivity with electromagnetic absorption, ensuring stable operation in high-frequency and high-power applications such as 5G, radar, automotive, and defense electronics.

Composed of an elastomeric matrix infused with thermally conductive and magnetic particles, the material minimizes thermal resistance while effectively suppressing electromagnetic interference.
Certified with UL94 V-0 flame retardancy and fully compliant with EU RoHS standards, it provides exceptional mechanical stability under extreme temperatures and harsh environments.
