Business
SANGBO Co., Ltd. is a South Korea-based advanced materials manufacturer engaged in the development, production, and global distribution of high-performance functional films, optical components, and nanotechnology-based coatings. The company operates across three core business divisions: Window and Surface Protection Films, Display Optical Materials, and Advanced New Materials. Its product offerings include automotive and architectural solar control window films; carbon, ceramic, and metal sputter thermal insulation films; automotive paint protection films (PPF) marketed under proprietary brand lines including EVIOUS; optical prism sheets and brightness enhancement films for backlight units (BLUs) used in liquid crystal displays (LCDs), OLED panels, televisions, monitors, and mobile devices; quantum dot (QD) optical sheets; scratch-resistant self-healing screen protection films; graphene barrier films and electromagnetic interference (EMI) shielding sheets; carbon nanotube (CNT) and silver nanowire (AgNW) transparent conductive films; and flexible copper clad laminates (FCCL) and dielectric substrates designed for 5G antenna modules and flexible electronic components. Founded in 1977 as Sangbo Chemical Industry and incorporated in 1989, the company is headquartered in Gimpo-si, Gyeonggi-do, South Korea, and supplies commercial, industrial, automotive, and consumer electronics markets throughout South Korea, China, North America, Europe, and Southeast Asia. In recent major corporate developments, Rayno Korea Co., Ltd., an affiliate of US-based Rayno WindowFilm Inc., acquired the founder's entire 14.81% equity stake in August 2026 to become SANGBO's largest shareholder, initiating a strategic integration to expand international distribution networks and scale automotive film operations. In addition, the company completed a reverse stock split in 2026, consolidating shares to raise its par value from 500 KRW to 2,500 KRW, while continuing the strategic commercialization and scaling of its graphene barrier and advanced functional optical film technologies.
