INNOX Advanced Materials

What INNOX Advanced Materials does

INNOX Advanced Materials Co., Ltd. (KOSDAQ: 272230) is a South Korea-based specialty materials manufacturer serving the global electronics value chain. Founded in 2001 as Saehan Micronix, renamed INNOX Corporation in 2005, and spun off as INNOX Advanced Materials in June 2017, the company operates a proprietary polymer chemistry platform spanning polyimide, epoxy, polyester, urethane, silicone, and acrylic resin systems, applied through precision coating, high-purity refining, defect-free coating, fine slitting, and defect inspection processes. The company functions as a B2B materials supplier organized into four product brands: INNOSEM (semiconductor PKG materials including DAF, QFN Tape, EMI Shielding Film, BGT, IBF), INNOLED (OLED display materials including encapsulation film, patterned film, OCA, and AR film), SMARTFLEX (FPCB materials including coverlay, bonding sheet, stiffener, EMI shielding, and TPU film), and INNOBM (battery and mobility materials including thermal runaway prevention pads and high elasticity pads for solid-state batteries).

The company holds the world's largest production capacity in semiconductor PKG and FPCB materials at its Asan facility (33,552,000 ㎡/year annual full CAPA, 88,168 ㎡ facility footprint), enabled by proprietary precision coating and converting technologies. It is Korea's only company with a full lineup of semiconductor PKG materials, and one of only one or two companies worldwide (centered on Japan) with full source technology. It serves approximately 150 customer companies across mobile/consumer electronics, semiconductor manufacturing, OLED display manufacturing, defense/aerospace (including SpaceX and Korean defense primes), and battery/EV segments. Revenue is generated through one-time sales of customized materials, with pricing quoted per engagement rather than published. Go-to-market combines direct enterprise sales with a Sales Network of domestic distributors (SCM Co., Ltd., TEXCELL, JESONE) and overseas entities across China, Hong Kong, Taiwan, Singapore, Malaysia, Japan, and the Philippines, plus overseas manufacturing subsidiaries IGC (Guangzhou, China) and INNOX VINA (Bac Ninh, Vietnam). The company's 2025 standalone revenue was KRW 4,396 billion (~USD 3.1B), with 18.6% consolidated operating margin and 34.7% gross margin.
