Precision-engineered dielectric potting compounds and functional thermal gels compliant with UL 94 V-0, RoHS, and US industrial durability standards.
Navigating next-generation electrical insulation, mechanical shock damping, and moisture resistance across key North American manufacturing corridors.
In recent years, the United States market for custom urethane potting compounds has witnessed transformative growth. With rapid re-shoring of advanced electronics manufacturing, expansion of green energy systems, and stringent safety standards set by Underwriters Laboratories (UL) and IEEE, standard off-the-shelf potting materials often fall short. OEMs and contract electronics manufacturers (CEMs) across Texas, Ohio, Michigan, California, and the East Coast demand tailored polyurethane chemistries that deliver a precise balance between elastomeric flexibility and rigid physical protection.
Polyurethane (urethane) potting resins are uniquely favored over traditional rigid epoxies for sensitive electronic assemblies because they generate minimal internal stress during cure, effectively protecting delicate surface-mount devices (SMDs), ferrite cores, and micro-wire bonds from thermal contraction cracking. Compared to silicones, custom urethanes provide superior abrasion resistance, high mechanical tear strength, and exceptional adhesion to various engineered plastics (ABS, PA66, PBT) and metallic housings without requiring costly chemical primers.
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.
Comprehensive functional polymer portfolio engineered to meet demanding US military, automotive, and industrial specifications.
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.
