Kingflex
Our core range of halogen-free, elastomeric thermal and acoustic barriers engineered specifically to meet the strict outgassing and safety parameters of high-tech building specifications across Seoul, Gyeonggi-do, and Busan.
High thermal performance sheet designed for electronic and optical cleanroom spaces preventing acidic micro-contamination.
Extruded elastomeric insulation sleeves optimized for pipe runs carrying chilled water or refrigerant in sensitive environments.
Specialized acoustic absorption media designed to damp high-frequency machinery noise in industrial and server centers.
Premium 40mm rubber foam for critical temperature holding systems, providing excellent thermal resistance values.
South Korea is home to some of the world's most sophisticated manufacturing clusters, including the **K-Semiconductor Belt** in Pyeongtaek and Yongin, alongside multi-gigawatt electric vehicle (EV) battery plants owned by LG Energy Solution, SK On, and Samsung SDI. In these critical ecosystems, traditional insulation materials present severe risks.
Standard elastomeric foam relies heavily on halogenated flame retardants (chlorine or bromine) to pass fire ratings. However, in the event of a thermal event or even localized overheating, these materials undergo pyrolysis, releasing hydrogen chloride (HCl) or hydrogen bromide (HBr) gases. In high-tech wafer cleanrooms, these toxic gases combine with humidity to form corrosive acids that instantly destroy millions of dollars of nanometer-scale photolithography equipment.
Our advanced manufacturing process controls physical and chemical metrics to deliver zero-halogen compliance.
Whether designing high-rise district cooling networks in Incheon, cryogenic systems in Ulsan shipyards, or cleanroom HVAC systems in Giheung, Kingflex provides systemic solutions that combine thermal control, moisture proofing, and severe safety standards.
Engineered with a highly uniform closed-cell structure (exceeding 98% closed cells) to block thermal bridging and moisture ingress. Preventing condensation on chilled water pipes is critical to maintaining relative humidity levels in ultra-precise lithography zones.
Specially tailored NBR/PVC elastomeric matrixes that sustain operational flexibility and physical integrity at cryogenic temperatures. Resists stress cracking under thermal shock on liquefied gas piping systems.
Open-cell and high-density variants provide superior sound absorption. Limits plant room decibel propagation to conform with Korea's strict Occupational Safety and Health Act (OSHA) thresholds.

Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Kingflex's research development and production department is located in Dacheng, China—the well-known capital of green building materials. It is an energy-saving, environmentally friendly enterprise concentrating on research, development, production, and sales.
In operation, Kingflex takes energy saving and consumption reduction as its core concept. We provide professional thermal insulation systems via consulting, customized R&D production, detailed installation guidance, and dedicated post-sale service to lead the sustainable development of the global industrial building materials sector.
Kingflex is established by the Jinwei Group, which has more than a 40-year history. Jinwei Group was established in 1979 and was the very first manufacturer of thermal insulation materials north of the Yangtze River. This long heritage informs our processing capability and rigorous quality inspection protocols.
Our employees are amazing in their own right, but together they are what makes Kingflex a dedicated partner for Korean infrastructure projects. The Kingflex team is a tight-knit, talented group with a shared vision of providing consistently first-class service to our clients.
Kingflex employs eight professional engineers in our R&D Department, 6 international customer managers, and over 230 skilled operators in the production department to guarantee fast lead times and precise customization.
Our materials undergo constant analytical validation inside our R&D centers to maintain compliance with international regulatory codes such as CE, REACH, RoHS, UL94, and ASTM.
With strict compliance at the core of our business model, Kingflex halogen-free and fire-retardant series are engineered to meet the demands of global classification societies. Every batch is traceable back to raw chemical inputs, ensuring that physical properties do not degrade over time in humid environments.
