Direct-from-manufacturer high-performance potting compounds meeting strict US testing benchmarks for automotive electrification, grid transformers, and radar electronics.
The North American industrial and commercial landscape is undergoing a massive transformation driven by vehicle electrification, renewable energy storage (BESS), utility grid modernization, and high-performance computing infrastructure. Across the United States—from automotive design hubs in Michigan and Ohio to green energy corridors in California, Texas, and the Sun Belt—electronic power densities are multiplying at an unprecedented rate.
As power modules shrink and operational voltages increase from 400V to 800V+ in automotive powertrains and commercial energy converters, traditional encapsulation materials often fail under persistent thermal throttling and partial discharge risks. Thermally conductive potting epoxy compounds engineered by Songxi Technology act as both a thermal highway and an impenetrable protective shield, preventing dielectric breakdown, mitigating mechanical vibration fatigue, and dissipating hotspot heat away from sensitive semiconductor junctions.
Songxi Technology is a dedicated high-tech enterprise focused on precision polymer materials designed for global mission-critical electrical and electronic assemblies.
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 and tailored customization of high-end electronic adhesives, helping intelligent devices across North America achieve greater stability and durability.
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.
Addressing stringent North American engineering specifications across tier-1 automotive manufacturing, renewable energy systems, and defense electronics.
US tier-1 automotive suppliers in Detroit and California require encapsulation materials capable of enduring severe under-hood thermal cycles and dynamic road vibration. Our thermally conductive potting epoxy stabilizes OBC inductive components, DC-DC converters, and inverter power stages, preventing partial discharge under 800V high-voltage architectures.
Grid-scale storage facilities throughout Texas, Arizona, and Nevada face intense outdoor ambient temperatures. Our potting systems provide structural integrity and flame-retardant thermal dissipation for Battery Management System (BMS) controller units, balancing cell temperature gradients and mitigating thermal runaway escalation risks.
Solar installations across the American Southwest demand encapsulation solutions that withstand high UV exposure, wide thermal swings, and moisture ingress. Songxi's polyurethane and epoxy compounds deliver superior hydrolytic stability and high thermal conductivity for power inductors and transformer potting.
Commercial aircraft assemblies and airborne radar platforms require dual-action encapsulation: high electromagnetic shielding and rapid heat dispersion. Our silver-filled and micro-filler epoxy matrices ensure over 60dB shielding effectiveness alongside rugged environmental sealing under extreme altitudes.
Heavy industrial facilities throughout the US Midwest rely on instrument transformers encapsulated with high-dielectric materials (≥25kV/mm). Songxi potting compounds eliminate internal air voids, ensuring zero insulation degradation under continuous inductive load conditions.
With data center clusters expanding rapidly in Virginia, Oregon, and Ohio, next-generation server PSUs require high-efficiency thermal potting to maintain compact footprint densities without relying on bulky heatsinks, guaranteeing 24/7 server stability.
Led by a Ph.D. in Polymer Materials from Sichuan University, Songxi's R&D team has nearly twenty years of silicone and epoxy application experience and has participated in over 100 product development projects. We maintain close technological cooperation with premier research institutions including Chenguang Chemical Research Institute, Sichuan University, and Beijing Institute of Technology.
Certified with ISO9001, Songxi operates a comprehensive quality management system covering raw material procurement, precision planetary mixing, vacuum defoaming, multi-stage filtration, inspection, and after-sales service. Our products comply with RoHS and REACH environmental directives, with SGS verification and UL 94 V-0 flame retardant certification, ensuring consistent batch-to-batch quality and reliable delivery to export clients across the United States.
Every formulation is tested using laser flash thermal conductivity analyzers, high-voltage breakdown testers, and automated rheometers to guarantee flowability in automated potting dispensers (meter-mix-dispense systems) common in North American production plants.

State-of-the-art manufacturing infrastructure ensuring high-purity synthesis and automated quality inspection.
Balancing cost competitiveness with uncompromising chemical stability, rapid customization, and export logistics reliability.
Unlike rigid multinational polymer corporations, Songxi works directly with US design engineers to adjust viscosity, pot life, cure schedules (room temp vs. heat accelerated), and thermal conductivities to integrate seamlessly into existing dispensing automation.
By eliminating multiple layers of international middle-distributors, we provide North American Tier-1 and Tier-2 manufacturers with direct factory pricing, significantly lowering bill-of-materials (BOM) costs across high-volume production lines.
All shipments are packaged to international dangerous goods (DG) and non-DG standards, complete with updated US GHS-compliant Safety Data Sheets (SDS), technical datasheets (TDS), certificates of analysis (COA), and full customs documentation.

Key information regarding international logistics, technical performance standards, and customized formulation development.
Our formulations feature optimized particle size distribution of high-purity inorganic dielectric fillers and ultra-low surface tension. This ensures excellent self-defoaming under vacuum degassing and eliminates microscopic air pockets that cause localized dielectric breakdown at voltages up to 800V-1500V.
Yes. Our core potting epoxy and silicone product lines are formulated with eco-friendly, halogen-free flame retardants, fully compliant with UL 94 V-0 standards to prevent combustion propagation in enclosed automotive and battery enclosures.
Absolutely. We formulate A/B mix ratios (e.g., 1:1, 2:1, 4:1, or 10:1), thixotropic index, and initial mixed viscosity specifically to match the pump heads, static mixers, and feed lines of automated dispensing systems used in North American factories.
Standard sample batches are dispatched within 3-5 business days. Commercial bulk orders typically ship within 2 to 3 weeks via ocean freight (Long Beach, Oakland, Houston, Savannah, New York/New Jersey) or expedited air cargo with complete customs and SDS paperwork.
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.
