Explore our certified thermal management and structural adhesive formulations engineered for North American high-spec electronic manufacturing.
An evolving electronic architecture landscape demands unprecedented thermal resistance and mechanical stability.
The rapid expansion of the North American EV corridor, multi-gigawatt grid storage systems, and fast-charging networks requires thermal polymers capable of continuous operation exceeding 180°C to 200°C without structural fatigue or dielectric breakdown.
As Silicon Carbide (SiC) and Gallium Nitride (GaN) power modules replace legacy silicon across US defense and aerospace systems, thermal epoxies must deliver high thermal conductivity (>3.0 W/m·K) paired with exceptionally low coefficient of thermal expansion (CTE).
Tier-1 US contract manufacturers prioritize polymer systems complying with UL 94 V-0 flame retardancy, low outgassing standards (NASA ASTM E595), and zero halogen limits while supporting automated high-speed dispensing and jetting processes.
Songxi Technology is a high-tech enterprise specializing in the R&D, production, and sales of electronic adhesives. Based on silicone, polyurethane, acrylic, and epoxy systems, we provide reliable bonding, sealing, and protection solutions for power electronics, optoelectronics, new energy, automotive, and aerospace industries.
We are committed to becoming a trusted provider of functional polymer material solutions for the electronics industry. Through continuous innovation and application development, we promote the localization of high-end electronic adhesives and help intelligent devices achieve greater stability and durability.
By synchronizing our custom molecular synthesis with the strict quality standards demanded by US and global OEMs, Songxi guarantees batch-to-batch consistency, minimal volatile organic content, and long-term joint integrity under severe thermal shock cycles (-55°C to +200°C).
Comprehensive adhesive technologies tailored for demanding operating conditions across global supply chains.
Songxi's business covers three functional areas: adhesive & sealing, potting & protection, and thermal interface materials. Our product portfolio includes PCBA fixing adhesives, UV adhesives, sealants, thermal conductive potting compounds, thermal greases, pads, two-component thermal gels, EMI shielding sealants, and reactive hot melt adhesives.
Our products serve power batteries, photovoltaic modules, drones, automotive electronics, 5G communications, and LED lighting. We provide both standard products and customized solutions for applications such as BMS conformal coating, IGBT thermal filling, and power battery structural bonding, supported by extensive technical experience and application expertise.
Proven high-reliability epoxy formulations tailored for key American high-tech industrial sectors.
Thermally conductive silver-filled epoxies and EMI shielding compounds designed for airborne phased-array radar, avionics control boxes, and missile guidance units requiring over 60dB attenuation and space-grade outgassing rates.
High dielectric strength adhesives for busbar insulation, cell-to-pack (CTP) structural thermal bonding, and IGBT substrate potting, eliminating high-voltage partial discharge hazards across high-voltage 800V platforms.
Two-component thermally conductive epoxy adhesives and gels optimized for high-power accelerators, ASIC power stages, and server liquid-cooling cold plates operating continuous 24/7 compute cycles.
Weather-resistant, UL 94 V-0 flame retardant potting compounds designed to protect commercial solar string inverters, wind turbine pitch controllers, and energy storage microinverters from extreme field thermocycling.
Led by a Ph.D. in Polymer Materials from Sichuan University, Songxi's R&D team has nearly twenty years of silicone application experience and has participated in over 100 product development projects. We maintain cooperation with research institutions including Chenguang Chemical Research Institute, Sichuan University, and Beijing Institute of Technology.
Certified with ISO9001, Songxi operates a comprehensive management system covering procurement, production, inspection, and after-sales service. Our products comply with RoHS and REACH requirements, with SGS verification and UL 94 V-0 flame retardant certification, ensuring consistent quality and reliable delivery.
Our modern laboratory houses advanced thermal conductivity meters (Hot Disk), rheometers, DSC analyzers, and high-voltage breakdown testers. Every batch destined for the United States market undergoes rigorous evaluation for viscosity consistency, lap shear strength, glass transition temperature (Tg), and thermal resistance.
With an emphasis on localized formulation adaptation, we assist US manufacturing clients in transitioning toward automated, high-yield dispense processes, reducing void generation and maximizing heat dissipation efficiency across mission-critical electronics.
State-of-the-art automated manufacturing facilities and qualified thermal polymer testing infrastructure.
Songxi adheres to integrity and quality throughout material selection, production, and delivery, turning reliability into a competitive advantage and earning long-term customer trust through professional service and continuous improvement across global markets.
Whether you need custom Tg modifications, low viscosity potting compounds for complex component geometries, or rapid-cure thermally conductive structural adhesives for US manufacturing lines, our engineering specialists are ready to collaborate on your next technical breakthrough.
