Business Areas

• Manufacturing and Supply of Engineering Plastic Materials: DYNEX directly produces and supplies the widest range of products in Korea, from high-performance engineering plastics such as PEEK and PEI to general industrial materials such as POM-C, CAST NYLON, PET, HDPE, PP, ABS, and PC. These materials possess lightweight properties, wear resistance, and heat resistance that can replace metals, making them core materials for precision machine parts and advanced process equipment.
• Technical Support and Process Solution Provision: Based on years of experience and know-how, we provide optimal process solutions tailored to customer needs. Through this, we actively support our customers in achieving results such as cost reduction, increased efficiency, and improved productivity.

Products

• PEEK (Polyetheretherketone): It is a top-grade super engineering plastic that maintains its physical properties even in extreme temperatures and chemical environments. It can be continuously used at high temperatures above 250 degrees Celsius and possesses excellent wear resistance and mechanical strength. Successfully localized for the first time in Korea in 2007, it is applied in various industrial fields.
• POM-C (Polyoxymethylene Copolymer): It is a semi-crystalline copolymer material with high mechanical strength, excellent processability, and dimensional stability. In particular, its water absorption rate is almost zero, providing superior mechanical properties and dimensional stability compared to nylon even in high humidity and submerged environments.
• CAST NYLON (Cast Nylon): This material is produced by polymerizing and molding liquid caprolactam, and DYNEX's technical team successfully localized it for the first time in Korea in 1985. It is a high-grade material that ideally combines high hardness, wear resistance, fatigue resistance, and excellent mechanical properties.

Special Notes

• Decades of experience and unique technology: Inheriting the legacy of its parent company established in 1965, DYNEX has accumulated unique technology and know-how in the field of engineering plastics for decades. It has secured technological competitiveness by successfully localizing key advanced materials such as PEEK, PEI, and CAST NYLON.
• Wide product lineup and customized solutions: We boast the widest product lineup in Korea, ranging from advanced super engineering plastics to general industrial materials. We manufacture standardized sheets and rods according to customer specifications and provide optimal process solutions and technical support.
• Contribution to national core industries and global competitiveness: We stably supply high-performance materials essential for national core strategic industries such as semiconductors, displays, automobiles, and medical devices. This contributes to import substitution and strengthening export competitiveness. In 2025, we were awarded the Export Tower on Trade Day, recognizing our technology and quality in the global market.
