Safely Suppress Electric Vehicle Fires with FIRESSAK
Large Co., Ltd. | CEO Park Cheol-hyun, Owner of the Fire Suppression Blanket Brand
As the transition to electric vehicles accelerates, side effects are also emerging. There is growing concern over the need to prevent damage from fire accidents caused by thermal runaway. Although various products specialized for electric vehicle fires are entering the market, many do not have the quality required to properly perform their intended role.
Large Co., Ltd., a materials-specialized company based in Daegu, is drawing attention after launching its own safety product brand, FIRESSAK, based on solid technological capabilities. Through years of research and development, the company has contributed to creating safer environments with a complete fire suppression solution.
Setting the Standard for Fire Suppression Blankets
Park Cheol-hyun, CEO of Large Co., Ltd., expressed confidence that FIRESSAK’s unique quality comes from setting its own standards. Park explained, “We realized that a product capable of preventing fire spread was truly necessary, so we began developing it ourselves. Our top priority was to create a brand that could become the standard for fire suppression blankets.”
The FIRESSAK Fire Suppression Blanket uses advanced materials rather than non-combustible fabric alone, providing high heat resistance. It also applies a sewing process that minimizes the generation of harmful gases. In addition, its durability has been strengthened so that it does not break during transport or installation, including through reinforced strap sewing.
Park said, “There were many difficulties in the early stages of development. It was natural to use fabric specialized for high temperatures, but there were structural limitations in which the sewn areas could melt or burst. When thermal runaway occurs in lithium-ion batteries, temperatures can soar above 1,000°C, so we made both the fabric and the thread capable of withstanding such conditions.”
He added, “Because this is a product used in fire situations, we are constantly working to improve its completeness.”
In actual tests conducted with fire authorities, Large Co., Ltd. successfully demonstrated electric vehicle fire suppression, proving the performance of its fire suppression blanket. The company also underwent multiple rounds of verification to obtain certifications. According to the company, even if similar products can be made using low-cost imported fabrics, such products may create even more dangerous situations. FIRESSAK has repeated thousands of tests and secured multiple certifications.
“Our pride in being the ‘real’ product comes from quality,” Park emphasized.
Last year, FIRESSAK won the Gold Award at the Public Procurement Competition and succeeded in obtaining certification as a safety innovative product. In line with the expansion of product supply, the company is also focusing on advancing its production processes and pursuing entry into overseas markets, including Vietnam.
High heat resistance and reduced harmful gases
Both fabric and thread specialized for high temperatures
Successfully proven in demonstrations with fire authorities
Expansion from innovative materials and components to disaster safety
Gold Award at the Public Procurement Competition
The Challenge of a Materials Company
Park, who majored in international trade at university, worked in the financial sector before joining the company. To build the business, he took on the role of a “multi-player,” handling everything from delivery and sales to field work and understanding technical drawings.
“When I came down to Daegu, there were only three employees,” he said. “I was determined to learn the work. I handled sales while digging into technical studies, came up with process improvement ideas, and put them into practice myself. That helped us build trust with customers. Not being ashamed of what I did not know and continuing to learn became the driving force behind our growth today.”
Park developed and mass-produced various advanced materials, growing the company’s scale, and became CEO in 2010. After relocating the headquarters to Technist, the company began its leap forward as an automotive materials and components company. From exhaust insulation materials, sound-absorbing and sound-insulating materials, and angle reinforcement materials to thermoplastic composites, the company established itself as a new materials company.
He explained, “We were able to diversify our business by accumulating technological capabilities in automotive materials and components. We focused on applying technologies that withstand heat and noise to the disaster safety field. These may be small, unseen parts in finished vehicles, but they are important elements that determine vehicle performance.”
He continued, “Automotive materials and components still account for a large portion of our business, and we continue working to advance related technologies. After building a solid foundation as a materials company, we believe expanding into disaster safety will allow us to aim for higher goals.”
Park said, “We are continuing to invest in our own brand, FIRESSAK. For now, we are focusing on fire safety, but our next goal is to expand our brand into other fields such as the environment and biotechnology.”
He added, “I want to create a reliable foundation for the employees who have worked hard with us, and I still hold firmly to that commitment. Rather than growing recklessly through aggressive investment, we want to build solid substance step by step. In the fields we pursue, we will become a truly strong small but competitive company recognized anywhere in the world.”
Park Cheol-hyun, CEO of Large Co., Ltd., stated his ambition, saying, “Our goal is to go beyond being an advanced materials company and enter the global market with our own brand, FIRESSAK.”
