Premium architectural and industrial cold insulation solutions engineered for thermodynamic stability and high moisture resistance.
In modern industrial processing, chemical refinement, and liquid gas distribution, maintaining thermal equilibrium is critical. Ultra-Low Temperature (ULT) systems (commonly spanning operating bounds from -40°C down to cryogenic thresholds) present a distinct physical challenge: extreme vapor drive. Because temperature differentials between the transport pipeline internal medium and local ambient conditions can exceed 100K, moisture in the air is continually driven inward toward the cold substrate.
Standard fiber-based insulation systems allow air and moisture penetration, resulting in condensation, ice buildup, physical sagging, and eventual under-insulation corrosion (CUI). Kingflex's signature Ult Insulation Sheet Roll addresses this by using a high-density, closed-cell NBR/PVC matrix. With over 98% closed cells, the material acts as a built-in vapor barrier, ensuring structural stability and thermal protection for critical pipe systems.
"Continuous, system-wide thermal efficiency is not merely about preventing heat gain; it is about absolute moisture exclusion. At cryogenic limits, a single breach in the vapor barrier degrades overall R-value exponentially as ice forms within the insulation."
Engineering procurement departments globally are prioritizing energy conservation and operational longevity. Whether specifying for a major district cooling plant in the Middle East, an LNG storage system in East Asia, or complex pharmaceutical HVAC networks in Europe, the selection of the correct elastomeric formulation dictates the overall carbon footprint.
Kingflex Insulation Co., Ltd. serves as an integrated solution provider. By establishing high-efficiency production centers in China's green-building material hub in Dacheng, we leverage localized raw materials and highly automated assembly lines to offer competitive factory quotes. This structure allows us to support major infrastructure developments with high-capacity production, ensuring global supply chain consistency.

Kingflex Insulation Co., Ltd. is established by the Jinwei Group, which carries a proud heritage of more than 40 years. Established in 1979, it was the first manufacturer of thermal insulation materials north of the Yangtze River.
Equipped with 5 large automatic assembly lines, our annual production capacity exceeds 600,000 cubic meters. Kingflex is a designated manufacturer for major chemical, power, and environmental projects.
Our dedicated team includes 8 professional R&D engineers, 6 international sales consultants, and 230 production technicians, all working toward providing reliable global insulation solutions.
At Kingflex, we believe that energy conservation starts with material innovation. Our chemical and mechanical engineers continuously work to improve NBR/PVC polymerization. By refining cellular dispersion and adjusting raw material ratios, we produce sheet rolls with low thermal conductivity and improved elasticity.
Our manufacturing plants operate under strict ISO guidelines, utilizing automated temperature control during cross-linking. This guarantees consistent material thickness and cell uniformity from batch to batch.
To serve international markets, our products are third-party tested to ensure they meet global commercial building codes and environmental directives. Kingflex sheet rolls and tubing comply with BS 476, CE, REACH, RoHS, UL94, and ASTM standards.
We export to over 66 countries, providing clear technical communication and documentation. Our customer support team handles inquiries from initial product specifications and custom requirements to shipping logistics.
Our insulation solutions are regularly selected for high-profile projects, including central HVAC systems in large commercial buildings, industrial piping networks, and low-temperature process lines.
Our Dacheng production facility features automated extrusion, foaming, cooling, and cut-to-length processing lines. This high level of automation ensures consistency across our entire product range, from standard NBR rolls to specialized cryogenic tube designs.
We offer targeted formulations designed to meet the demands of various industrial environments. Here is an overview of how Kingflex elastomeric materials perform in key applications.
In large commercial air conditioning systems, maintaining temperature control and managing acoustic levels are essential. Kingflex High Density Acoustic Rubber Foam Boards provide thermal efficiency to prevent duct condensation while dampening structural and airflow noise.
Piping carrying liquified natural gas (LNG) operates at extreme sub-zero temperatures. At these levels, traditional insulation can crack due to thermal contraction. Kingflex Flexible Cryogenic Insulation uses specialized plasticizers to maintain flexibility, preventing thermal stress fractures and protecting the piping.
While elastomeric foam is primarily used for cold insulation, our NBR/PVC blends perform reliably up to 105°C. For industrial process steam and high-temperature lines, we offer complementary rock wool and mineral fiber systems to provide thermal protection and meet safety standards.
