UNID BT+ Acquires Stake in Thermal Material Specialist OCSmaterials
2025.12.05UNID BT+ (CEO Sang-Joon Han) announced on the 15th that it has acquired 85,714 shares of OCSmaterials, a leading manufacturer of thermal interface materials, for approximately KRW 6 billion (about USD 4.3 million).
Following the equity investment, UNID BT Plus now holds a 29% stake in OCSmaterials. As of Q1 2024, UNID BT Plus maintains a stable financial structure with KRW 100 billion in cash-equivalent assets and a debt ratio of 16%. Through this investment, the company plans to expand beyond its traditional wood-based panel business and secure a new growth engine in the thermal materials sector.
OCSmaterials specializes in thermal management solutions for electric vehicles and electronic devices, as well as EV thermal-runaway protection pads. Leveraging its proprietary synthesis technology, the company develops customized products for diverse applications and contributes to the localization of advanced thermal materials required for EV fire-prevention systems, an area gaining increasing importance as EV adoption grows.
UNID BT Plus stated that the investment reflects strong confidence in OCSmaterials’ differentiated technological capabilities. As automotive batteries and IT devices continue to move toward miniaturization, multifunctionality, and high integration, demand for high-performance thermal materials is expected to surge. In particular, OCSmaterials’ ongoing development of flame-retardant materials designed to block thermal runaway in EVs is emerging as a critical component for enhancing EV safety.
A UNID BT Plus representative commented,
"This investment marks an important milestone in diversifying our business portfolio beyond our existing operations. By entering the high-potential thermal materials industry, we expect to strengthen our corporate competitiveness and overall enterprise value. Moving forward, we will continue to pursue strategic investments and technology development to secure new growth drivers."
UNID BT Plus, spun off from UNID’s wood materials division, has been actively expanding its business domains. Following the launch of its proprietary MDF flooring brand, “OlGoda,” the company recently entered the hydrogen-safety market and has been developing HyFinder, a hydrogen-leak detection system, as part of its efforts to secure future growth opportunities.
