Kingflex
Explore our top-tier exterior pipe and equipment insulation options, manufactured utilizing advanced rubber-plastic extrusion technologies for demanding industrial applications.
Critical energy saving policies, climate imperatives, and structural sustainability drive the demand for high-performance exterior insulation systems.
Unlike indoor environments where ambient temperatures are relatively controlled, exterior pipelines are subject to intense thermodynamic cycles, wind-washing effects, UV degradation, precipitation, and extreme temperature variations (-40°C to over 100°C). Standard insulation systems frequently fail due to moisture ingress (vapor drive), leading to Corrosion Under Insulation (CUI). Our NBR/PVC closed-cell matrix offers a built-in water vapor barrier with a moisture resistance factor (μ-value) exceeding 10,000, eliminating the reliance on secondary vapor barriers and safeguarding structural assets from corrosion.
In accordance with global environmental benchmarks such as ASHRAE 90.1, EN 12828, and green building certification systems like LEED and BREEAM, reducing operational carbon emissions is imperative. High-efficiency thermal insulation prevents thermal energy losses from HVAC ducts, hot water lines, and chemical processing networks. By ensuring a low and stable thermal conductivity (λ ≤ 0.034 W/(m·K) at 0°C), our materials allow global contractors to achieve targeted energy reductions and secure localized compliance with rigorous ecological policies.
Strategically positioned in Dacheng, China—the capital of green building materials—Kingflex delivers industrial-scale efficiency, raw material integration, and consistent quality.
Kingflex operates 5 large-scale automated assembly lines. This highly advanced extrusion setup enables an annual production output exceeding 600,000 cubic meters. By automating the compound formulation, mixing, extrusion, continuous vulcanization, and foaming stages, we maintain precise density controls and eliminate human errors in the cell structure formation.
Our localized supply chain in Dacheng minimizes raw material transport costs and secures stable component supply. This clustering effect directly translates to a competitive cost structure. We pass these savings directly to our global distribution partners and industrial procurement managers through optimized FOB/CIF pricing schemes.
Recognized for outstanding energy-saving contributions, Kingflex is a designated manufacturer approved by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry in China. This status reflects our strict commitment to national manufacturing benchmarks and international standards.
Kingflex was established under the Jinwei Group, a leading pioneer with over 40 years of manufacturing history. Founded in 1979, Jinwei Group was the first manufacturer of thermal insulation materials located north of the Yangtze River. Decades of research, development, and engineering expertise are baked into every cubic meter of elastomeric foam we produce today. Our legacy guarantees not only product performance but the structural longevity of your complex projects.

Cryogenic networks require exceptional structural flexibility and cell integrity to handle thermal shock down to -200°C.
Under cryogenic conditions, moisture ingress is the single greatest cause of insulation failure. Ice formation within the insulation cracks traditional materials and destroys thermal values. Kingflex cryogenic elastic rubber foam maintains structural flexibility at temperatures down to -200°C. The closed-cell configuration prevents moisture from migrating through the insulation layer, protecting LNG terminals and petrochemical process piping.
To support extreme application scenarios, Kingflex invests heavily in R&D. Our facility is staffed by 8 professional research and development engineers. We simulate field environmental stressors, evaluating tensile strength, compression resilience under thermal loading, dynamic shear resistance, and oxygen index metrics.
This data gives engineers the assurance that our formulations can cope with wind loads, structural expansions, and the environmental exposures standard in coastal petrochemical plants and cold-climate LNG ports.
Our industrial thermal and acoustic insulation range passes rigorous global fire and material safety standards.
Quality Traceability System: Kingflex implements a serial-number tracking protocol from raw compounding to dispatch. Every sheet roll and pipe insulation batch can be traced back to its raw material component lot, production line parameters, and specific quality control inspections.
From central HVAC plants to complex industrial process pipelines, Kingflex meets specific regional and structural installation requirements.
Applied to central air conditioning water piping and ventilation ducts in hospitals, shopping centers, airports, and hotels. Prevents condensates from dripping into ceilings and optimizes energy efficiency.
Designed for process pipelines, tanks, and chemical equipment. High chemical resistance ensures NBR/PVC elastomeric structures remain stable when exposed to oils, acids, and alkalis typical in industrial plants.
Used to line cold storage walls, refrigeration equipment, and train carriages. The lightweight, flexible structure is ideal for transportation applications where mechanical vibrations occur.
Key factors for supply chain leaders and engineers when specifying and purchasing pipe insulation from China.
