Business
YeSUN Tech Co., Ltd. is a South Korea-based functional adhesive materials manufacturer that specializes in the engineering, fabrication, and distribution of high-performance adhesive tapes, precision pads, and thermal management solutions for the display, automotive electronics, and secondary battery industries. Founded in 2005 and headquartered in Gunpo-si, Gyeonggi-do, South Korea, the company maintains manufacturing facilities and sales networks across South Korea, China (Guangzhou and Suzhou), Vietnam (Haiphong), and Indonesia (Cikarang). YeSUN Tech provides a comprehensive portfolio of precision-engineered adhesive components, including functional foam pads and gasket pads for OLED and LCD module shock absorption, sealing, and light leakage prevention; optical and double-sided adhesive tapes for display panel and mobile device assembly; thermal interface materials (TIM) and heat-dissipation sheets for electronic temperature regulation; electromagnetic interference (EMI) shielding tapes; surface protection films; and structural bonding tapes for automotive electronic components and vehicle interiors. In recent strategic developments, the company has expanded its focus into the electric vehicle (EV) and energy storage system (ESS) battery markets through the launch and commercialization of patented high-temperature Flame Barrier Tapes and dual-layer flame-retardant sheets engineered to prevent thermal runaway propagation at temperatures exceeding 1,300 degrees Celsius, which secured UL94 V-0 flame-retardant certification and received the KES Innovation Award. Additionally, YeSUN Tech executed a five-to-one share consolidation in 2026 to optimize capital structure and trading liquidity, achieved a turnaround to consecutive quarters of operating profitability through operational realignments, and advanced supply chain integration with global automotive and electronic display manufacturers.
