Kingflex
High-efficiency thermal control materials optimized for chilled water lines, industrial piping systems, and energy saving HVAC solutions.
In modern industrial and commercial building systems, the efficiency of chilled water circulation is highly dependent on the integrity of the thermal barrier wrapped around the pipeline. A flawed insulation system on a chilled water circuit doesn't just waste energy—it causes condensation, water pooling, biological growth, structural decay, and structural failure through Corrosion Under Insulation (CUI).
Kingflex Insulation Co., Ltd. is a leading integrated developer and manufacturer specializing in high-performance elastomeric insulation. Nestled in Dacheng, China—the green-building materials capital—Kingflex operates a facility that bridges state-of-the-art polymer science with highly robust thermal management engineering. We don't just sell insulation; we engineer systems to maintain thermodynamic equilibrium over decades of operation.
Established under the wing of the Jinwei Group, which carries a legacy of over 40 years, Kingflex inherits an unmatched foundation in material development. Founded in 1979, Jinwei Group was the pioneer manufacturer of thermal insulation materials north of the Yangtze River.
Building on these generations of experience, Kingflex specializes in combining polymer flexibility with high-density thermal performance. Our custom-blended NBR/PVC closed-cell structures ensure optimal performance under extreme humidity gradients and temperature changes.

Pipes must be pressure tested and fully cleaned of dirt, grease, and rust. Applying a high-grade rust inhibitor helps mitigate the threat of Corrosion Under Insulation (CUI) when exposed to varying cold-warm cycles.
Measure the outer diameter of the pipe and matching insulation tube. Slit the Kingflex elastomeric pipe longitudinally using clean sharp tools, or use our pre-slit self-adhesive tubes for accelerated installation speeds.
Apply a uniform coat of Kingflex Thermal Insulation Glue 520 to both clean-cut edges. Allow it to become tack-free (wet adhesive will trap air and cause early joint failure). Gently press the seam closed.
Compression fit all adjacent foam tubes, compression sealing butt joints using adhesive. For complex fittings (tees, elbows, valves), cut the Kingflex elastomeric sheet or pipe to form template-matched covers.
In chilled water applications, moisture travels from the warm ambient air toward the cold pipe surface. Check that the closed-cell membrane (water vapor resistance factor μ ≥ 10,000) is continuous without any tears.
Ensure hangers do not compress the insulation (use insulated pipe supports or rigid inserts). Verify all joints are chemically sealed. Let the glue cure fully (typically 24-36 hours) before running the cold fluid.

Driving the future of commercial insulation through polymer advancements, carbon neutrality, and smart monitoring integration.
Integrating graphene and silica aerogel matrices into standard NBR/PVC blends to push thermal conductivity limits down to 0.028 W/(m·K), reducing space consumption in congested conduits.
Phasing out fossil-derived rubbers for bio-based elastomeric polymers. This initiative lowers overall carbon footprints and aligns with global Net-Zero construction goals.
Developing sensor-embedded insulation wraps that monitor real-time relative humidity beneath the insulation. This allows facilities to detect moisture infiltration before rust forms.
Adapting thermal science to meet the operational demands of massive infrastructure projects around the world.
Modern data centers run continuous liquid-cooling operations. Any drop in temperature efficiency leads directly to increased Power Usage Effectiveness (PUE) ratios and potential server risks.
At sub-zero and cryogenic temperatures, conventional materials become brittle and lose their insulation value. Kingflex cryogenic systems use multi-layered elastomeric membranes to manage temperature drops down to -196°C.
Maintaining a stable global supply chain requires massive scale and automated control. Kingflex operates 5 large-scale automated assembly lines in Dacheng. This centralized manufacturing system guarantees fast production turnarounds and stable material chemistry.
With an annual capacity exceeding 600,000 cubic meters, Kingflex is designated as an approved manufacturer by the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry. This high capacity allows us to supply massive commercial projects worldwide on time, every time.
