SFA series of hybrid gel offers exceptional thermal performance, microwave absorption, low compressibility, and high reliability. Designed for versatile applications, it provides excellent gap adaptability, making it highly effective in ensuring full contact between mating parts, which enhances heat transfer efficiency.
Unlike thermal grease, the SFA series gel has no settling or flow issues, making it an ideal solution for dispensing, screen printing, or squeegee coating. Its unique formulation ensures consistent performance without the mess or complications often associated with traditional thermal greases.
Our Hybrid Thermal & RF Absorber solutions offer the dual benefit of high-performance heat dissipation and superior electromagnetic interference shielding. To ensure these multi-functional materials meet global electronics standards, we verify our shielding effectiveness using benchmarks set by the IEEE 299 standard. This guarantees that every Hybrid Thermal & RF Absorber provides reliable thermal management while effectively eliminating unwanted high-frequency noise in sensitive aerospace and telecommunications hardware.
