Explore our high-performance closed-cell elastomeric rubber foam sheets, rolls, and tube systems designed for cryogenic and low-temperature engineering applications.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Located in Dacheng, China—the well-known capital of green building materials—we are an energy-saving, environmentally friendly enterprise concentrating on research, development, production, and global sales.
We operate with energy saving and consumption reduction as our core concept. By integrating professional design consultation, advanced product manufacturing, on-site installation guidance, and dedicated post-sale services, Kingflex continues to lead the global building materials and refrigeration logistics sectors.
Providing robust systemic solutions to counter energy losses, carbon output, and operational challenges in large-scale modern thermal designs.
Modern commercial and industrial facilities operate under strict energy efficiency mandates. Sub-ambient and chilled water refrigeration piping are highly susceptible to thermal gains and ambient condensation. Moisture buildup on cold surfaces not only leads to systemic energy loss but also fosters structural mold and triggers CUI (Corrosion Under Insulation), potentially compromising pipework structural integrity.
Kingflex elastomeric closed-cell insulation maintains a high resistance to moisture diffusion. With a closed-cell ratio exceeding 98%, it eliminates the need for independent vapor barriers. This guarantees long-term stable thermal conductivity ($\lambda \leq 0.034 \text{ W/(m}\cdot\text{K)}$ at $0^\circ\text{C}$), protecting your systems and lowering carbon emissions by reducing mechanical cooling requirements.
Established by the Jinwei Group, which boasts over 40 years of industry history since its founding in 1979, Kingflex stands as the pioneer manufacturer of thermal insulation materials north of the Yangtze River.
Adapting insulation solutions to complex industrial processes, sub-zero refrigeration pipelines, and severe marine/offshore conditions.
Providing specialized multi-layered systems for ultra-low temperature and cryogenic processes. Our NBR/PVC and diolefin rubber structures maintain flexibility down to -200°C, limiting thermal contraction fractures.
Fiber-free, low-VOC manufacturing guarantees compatibility with critical cleanroom parameters in semiconductor facilities, pharmaceutical plants, and hospitals. Highly effective against microbial accumulation.
In highly intensive server cooling setups, moisture condensation can trigger catastrophic hardware failure. Kingflex closed-cell technology offers a reliable barrier on chilled liquid supply lines.

A look at our factory floor, raw material storage, automated production lines, and final packaging yards.
Developing next-generation insulation systems with advanced raw materials, sustainable foaming agents, and intelligent temperature monitoring capabilities.
In response to the evolution of international building regulations, Kingflex's engineering team is developing halogen-free, bio-based closed-cell compounds. Our R&D center is testing green foaming technologies that minimize environmental impact without compromising flame-retardant properties or thermal resistance.
We are also researching multi-layered cryogenic barriers that integrate aerogel technologies. These composite designs are engineered to offer high thermal resistance with reduced material thickness, serving the demands of deep-sea LNG transport, liquid hydrogen storage, and compact aerospace projects.
Achieving a 30% reduction in production energy consumption by optimizing extrusion lines and incorporating recycled polymer feedstocks into non-critical insulation blends.
