Engineered high-efficiency thermal gels and TIM compounds designed for low assembly stress, deep cavity gap filling, and waterproof potting protection.
Addressing high current densities, continuous peak wattage, and severe atmospheric ingress challenges in modern commercial and industrial UAV flight systems.
Industrial payload drones, eVTOL aircraft, and high-performance FPV platforms push electronic speed controllers (ESCs) to handle immense switching currents (exceeding 80A to 200A continuous). The resulting localized thermal surge across tiny GaN/SiC and MOSFET switches requires low-thermal-resistance potting gels to evacuate heat rapidly to the aluminum enclosure or chassis airframe.
Modern UAVs operate across agricultural chemical spraying, sea-surface offshore monitoring, high-altitude sub-zero flights, and torrential rainstorms. Unprotected ESC mainboards are highly susceptible to moisture ingress, salt mist corrosion, short-circuits, and dust build-up. Thermal potting gels offer seamless dual-action heat mitigation and complete waterproof/chemically inert hermetic encapsulation.
Unlike rigid epoxy potting compounds that risk ripping fragile surface-mount micro-components during rapid thermal expansion cycles or high-frequency propeller harmonics, two-component soft thermal silicone gels maintain viscoelastic flexibility. They absorb vibrational shocks, buffer mechanical strain, and prevent micro-cracking across solder joints.
Drone Electronic Speed Controllers (ESCs) present a complex topographical landscape: towering electrolytic capacitors, low-profile MOSFET gate drivers, precision microcontrollers, and uneven copper shunts. Standard thermal pads fail to conform uniformly without imposing damaging mechanical compression on fragile components, leaving micro air gaps that act as thermal insulators.
Songxi's specialized two-component thermal gel for Drone ESC mainboards flows under low dispensing pressure to achieve total wet-out across micro-irregularities. Upon room temperature or heat-accelerated cure, it transforms into an ultra-compliant elastomer with negligible oil bleed, outstanding dielectric breakdown strength (>10 kV/mm), and continuous thermal conductivity ranging from 2.0 W/m·K to 6.0 W/m·K.
