Kingflex
Engineered closed-cell NBR/PVC elastomeric thermal insulation systems tailored to withstand massive seasonal temperature variations from -40°C in Northern Kazakhstan (Astana) to +40°C in Southern regions.
Kazakhstan, the economic hub of Central Asia, is experiencing unprecedented growth in its industrial manufacturing, petrochemical refining, and commercial construction sectors. From the vast oil fields of Atyrau and Tengiz to the metropolitan expansions of Almaty and Astana, infrastructure resilience is critical. The extreme continental climate—characterized by winters reaching as low as -40°C and summers exceeding +40°C—demands heavy-duty thermal insulation products with high thermal efficiency and condensation control.
Under these challenging climatic scenarios, standard insulation materials often fail due to moisture ingress, freezing, or mechanical degradation. Kingflex's closed-cell elastomeric rubber foam sheets provide a reliable barrier, offering thermal conductivity (λ) down to ≤ 0.034 W/(m·K) at 0°C and a vapour diffusion resistance (μ value) exceeding 10,000. These characteristics prevent condensation in HVAC chillers and process pipelines, saving energy and avoiding under-insulation corrosion (CUI) in major industrial facilities.
Our global production footprints enable us to manufacture and ship high-end elastomeric systems meeting BS 476, CE, REACH, ROHS, UL94, and ASTM guidelines.
Modern insulation technology has moved past basic fiberglass and rock wool for moisture-prone areas. The global trend shifts heavily toward closed-cell materials, which integrate both thermal insulation and moisture barriers in one application. The NBR/PVC matrix of Kingflex Rubber Foam features micro-chambers that restrict moisture and air passage. This keeps the material's thermal properties stable over its 10 to 15-year service life, even in highly humid process plants or sub-zero cryogenic systems.
In addition, sustainability regulations in Europe and Asia demand low VOC emission profiles and clean blowing agents. Our R&D division has developed zero-halogen and low-smoke formulations that perform exceptionally in high-safety projects like airports, medical complexes, and underground transport systems.
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 the well-known capital of green-building materials in Dacheng, China. 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 insulation solutions by means of consultation, research and development, production, installation guidance, and post-sale service to lead the development of the global building materials industry.
Kingflex is established by the Jinwei Group, which has more than 40 years of history. Established in 1979, Jinwei Group was the first manufacturer of thermal insulation materials north of the Yangtze River. The group's extensive experience forms the technical backbone of Kingflex's manufacturing standards.
Our employees are amazing in their own right, but together they make Kingflex a rewarding place to work. The Kingflex team is a tight-knit, talented group with a shared vision of providing first-class service to our clients. Kingflex has eight professional engineers in the R&D Department, 6 professional international sales specialists, and 230 workers in the production department. Our engineers ensure every run of NBR/PVC foam conforms to fire resistance, thermal conductivity, and environmental compliance targets.
