SINGAPORE and LUXEMBOURG, Sept. 2, 2024 — Armacell, a global leader in flexible foam for the equipment insulation market and a leading provider of engineered foams, along with its joint venture partner JIOS Aerogel (“JIOS”), a global leader in silica aerogel technology, announced today that Armacell has acquired all JIOS shares in Armacell JIOS Aerogels Limited (“AJA”). This transaction marks the outcome of the joint venture’s remarkable success and comes at a time when JIOS is focusing its efforts on the electric vehicle market, and Armacell continues to invest in scaling up its aerogel production capacity.

The joint venture, AJA, was established in 2016 to produce silica aerogel products using JIOS’s patented manufacturing process, with sales and marketing managed by Armacell’s global network. Since its inception, AJA has established a strong presence in the energy industry, with its highly successful ArmaGel^® product line for high-temperature and cryogenic insulation. Aerogel is renowned as the world’s lowest density solid material known for its exceptional insulation efficiency. AJA’s manufacturing facility in Cheonan, South Korea, boasts an annual production capacity exceeding 700 tonnes of aerogel powder, with plans for immediate expansion to support the ongoing growth of its business.

Stephen Kang, CEO and Co-Founder of JIOS, expressed his enthusiasm: “We are delighted to have supported the establishment and growth of a profitable company, and to have now realized the value of this investment. The joint venture has demonstrated the exceptional performance and value of JIOS technology in producing silica aerogels on a large scale.“

As Laurent Musy, President and CEO of Armacell, stated: “This acquisition acknowledges the success of the joint venture that began eight years ago. It represents a significant step forward in Armacell’s strategy to strongly grow its energy and industry business, particularly through technological innovations, increased capacity in aerogel manufacturing and exceptional service capabilities.“

With this transaction, AJA becomes a wholly-owned subsidiary of Armacell and continues to operate under an evergreen licence agreement from JIOS for the use of its patented aerogel powder production technology. JIOS’s divestment from the AJA joint venture will allow it to focus more keenly on providing aerogel solutions that mitigate thermal runaway in electric vehicles.

The terms of the transaction remain confidential.
