Precision-engineered epoxy adhesive glues designed to meet stringent American manufacturing standards (ASTM, UL, IPC, and MIL-STD specifications).
The United States structural epoxy and electronic encapsulant sector is experiencing unprecedented growth, accelerated by clean energy initiatives, domestic semiconductor packaging reshoring, and advanced aerospace manufacturing hubs.
From the Midwest automotive corridor to Texas and Nevada EV battery plants, structural epoxies play a crucial role in battery cell-to-pack (CTP) structural adhesion, high thermal conductivity heat dissipation, and dielectric breakdown mitigation in 800V silicon-carbide architecture.
U.S. defense contractors and commercial space innovators in California, Florida, and Washington require high-reliability silver-filled conductive epoxies with >60dB EMI shielding, NASA outgassing compliance (ASTM E595), and sustained resilience under extreme cryogenic-to-high temperature cycling.
With massive investments in domestic chip fabrication across Arizona, Ohio, and Oregon, our high dielectric strength, low ionic impurity component-fixing adhesives prevent solder pad electrochemical migration and deliver micro-dispensing precision on dense surface-mount assemblies.
North American environmental frameworks demand low-VOC, solvent-free, non-hazardous chemistry. Songxi’s epoxy systems are 100% compliant with California Proposition 65, RoHS 3, and REACH standards, providing secure importing pathways without regulatory friction.
Solar inverters, wind power control electronics, and utility-scale Energy Storage Systems (ESS) deploy our high-shear elastic sealants and potting compounds to endure extreme outdoor UV radiation, thermal shock, moisture ingress, and seismic vibrational stresses.
Flame retardancy is non-negotiable for commercial building electronics and consumer appliances in North America. Our epoxy polymers feature inherent self-extinguishing chemistries certified under Underwriters Laboratories (UL) 94 V-0 flammability criteria.
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 in demanding operating environments across the United States.
Meeting North American industrial requirements through standardized bulk exports and tailor-made formulations for critical electronics and structural assemblies.
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.
Led by a Ph.D. in Polymer Materials from Sichuan University, Songxi's R&D team has nearly twenty years of silicone and advanced epoxy application experience and has participated in over 100 product development projects. We maintain close cooperation with top research institutions including Chenguang Chemical Research Institute, Sichuan University, and Beijing Institute of Technology.
