Enbionia, a company specializing in advanced composite materials, announced on July 8 that it is now supplying its ceramic-based flame-retardant material (Ceramic Paper) for ESS to major domestic conglomerates.
This mass production of Ceramic Paper marks the first successful localization of this material in Korea. Since 2022, Enbionia has been conducting joint research and development with major domestic conglomerates, completing product standardization and performance testing. After the first supply in January this year, full-scale mass production began in May. The Ceramic Paper supplied by Enbionia is a key material used to prevent thermal runaway in ESS and EV batteries. Notably, it is the first time a domestic company has developed and localized this product, and the company is currently supplying quantities worth 300 to 400 million KRW per month. The company expects the supply volume to expand rapidly in the future.
Since 2022, Enbionia has invested more than 8 billion KRW in facility upgrades, optimizing its mass production process in October last year. The company is currently working to improve production efficiency with the goal of establishing a 24-hour continuous operation system and expects to achieve full-scale operation soon.
Ceramic Paper is a paper-type material made using a wet process from composite materials such as ceramic fibers. It maintains its shape and performance even at temperatures above 1,100°C. Its strengths include low thermal conductivity and eco-friendliness, as it poses no harm to humans. Related products and manufacturing methods have been registered for domestic patents. Through a PCT international patent application in 2022, the company is also preparing to enter global markets such as the United States, China, Europe, and Japan.
Enbionia's annual production capacity is approximately 40 billion KRW. Since the product has been confirmed as meeting the customer specifications of domestic battery manufacturers, and considering that the order volume in the ESS market has already reached several trillion KRW, the company expects its supply volume to expand significantly in the future.
In addition to ESS and EV applications, Ceramic Paper is also used as a heat-resistant and insulating material in industries that require significant thermal energy, such as steelmaking, steel mills, power plants, and chemicals. Compared to conventional ceramic felt, it is thinner, more uniform, and denser, making it highly regarded as an insulating and insulating material for precision components in high-temperature environments. In the global market, companies such as Morgan in the United Kingdom and 3M in the United States supply similar products for use in aircraft, automobiles, and high-temperature gaskets. Enbionia is also working with several major domestic conglomerates to apply the product for mass production.
A representative from Enbionia stated, "Due to embargo agreements with domestic conglomerates, we cannot disclose specific details, but the results of our bold R&D and facility investments are becoming visible," adding, "We also plan to announce the results of various advanced composite materials currently under development soon."
Han Jeongcheol, CEO of Enbionia, emphasized, "We are focusing all our company resources to quickly respond to the demand for ceramic-based composite materials," and added, "This achievement is only the beginning. Through mass production and sales of high-quality Ceramic Paper, we aim to be re-evaluated as Korea's top materials, parts, and equipment company."
