Since its establishment in 1984, Deukyoung Co., Ltd. has been a non-woven and felt manufacturer specializing in special materials for electric wires, such as water-swellable tapes and waterproof yarns for power and communication cables. Headquartered with production facilities in Samseong-myeon, Eumseong-gun, Chungcheongbuk-do, the company was the first in Korea to localize the development of water-swellable tapes for electric wires, supplying them stably to domestic and international cable markets. Based on excellent technical capabilities and thorough quality control, the company has achieved numerous export records and is recognized for its competitiveness in the global market.

"Deukyoung Co., Ltd. is a company that produces and sells water-swellable tapes and yarns for electric wires. Founded in 1984, we were the first in Korea to design and develop these products, and we continue to be recognized by customers in domestic and international cable markets for our superior quality. Furthermore, based on our QA, QC, and R&D systems, we produce, sell, and service world-class products with a quality-first philosophy and pursue continuous innovation to achieve customer satisfaction."

Business Areas

• Manufacturing of Special Waterproof Tapes and Fabrics for Electric Wires: We develop and produce water-blocking swelling tapes and semi-conductive/non-conductive binding tapes applied to power, communication, and submarine cables. By swelling immediately upon moisture penetration, it blocks cable damage and flooding, helping to maintain the original function and lifespan of the wire.
• Swelling Yarn and Powder Materials for Electric Wires: We manufacture special waterproof swelling yarns and waterproof powders for conductors that fill gaps inside cable cores and block moisture diffusion. We provide high-performance chemical and textile material solutions optimized for dry-type waterproof systems.
• Manufacturing of Industrial Polymer Desiccant Rotors: Through our technical research institute, we have developed low-temperature regeneration polymer desiccant rotors and established pilot and mass production facilities to expand our business area. We are pioneering new markets based on our proprietary technology in the field of core components for air conditioning and dehumidification equipment.

Products

• Semi-conductive / Non-conductive Swelling Tape: A special tape that contains super absorbent polymer (SAP) that expands rapidly upon contact with water to completely block moisture from entering the cable. It is manufactured in various specifications, including 1-PLY (Single Layer) and 2-PLY structures, as well as semi-conductive and non-conductive types.
• Swelling Yarn: A special yarn for electric wires applied to the gaps inside optical cables and power lines; it swells immediately upon flooding to prevent water ingress inside the wire. It is a material that replaces existing compound filling methods by improving weight reduction and work convenience.
• Desiccant Rotor: A low-temperature regeneration desiccant rotor with high energy efficiency, used as a functional component in air conditioning equipment and cleanroom dehumidification systems. Applied with polymer desiccant material technology, it exhibits excellent moisture adsorption and regeneration performance.

Special Notes

• Super Absorbent Polymer (SAP) Compounding Technology for Cables: By using super absorbent polymers specialized for the wire industry rather than general hygiene products, we have secured excellent thermal stability and long-term durability. In the event of damage to the cable sheath, the initial water absorption is rapid, minimizing moisture diffusion and the scope of cable damage.
• Patented Method for Preventing Powder Shedding and Dust: Through single-layer water-swellable tape manufacturing technology applying patented techniques, we prevent powder shedding and dust during use. This not only maintains a clean work environment but also prevents workers from inhaling dust and ensures long-term waterproof performance.
• Extensive Experience and Proven Global Export Competitiveness: Based on know-how accumulated since our founding in 1984 and ISO 9001 and Inno-Biz certifications, we supply products to leading cable manufacturers around the world. We maintain high credibility in the global market, having been awarded the $5 Million Export Tower on Trade Day.

💡 A Word from JOBPLOY
Deukyoung Co., Ltd. is a promising small and medium-sized enterprise that produces special waterproof tapes and functional non-woven fabrics essential for electric and optical cables. In the production field, machine operation such as fabric coating, roll winding, cutting, and packaging, as well as material handling, are the primary tasks, so wearing safety gear and following on-site safety rules are very important. As we handle high-quality wire materials, careful attention to reduce product defect rates and a diligent work attitude according to process manuals are required.
