Direct supply from China's industry-leading energy-saving insulation manufacturing lines.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for high-performance thermal insulation products. Our cutting-edge research, development, and massive production departments are located in Dacheng, China—the globally recognized capital of green building materials.
Operating with a foundational core concept centered on environmental energy saving and consumption reduction, Kingflex provides integrated insulation system solutions. From expert engineering consultation, custom material formulation research, high-volume automated manufacturing, to global onsite installation guidance, we drive technological excellence across the worldwide construction and industrial piping sectors.
Established by the prestigious Jinwei Group, which possesses more than 40 years of pioneering history, our roots date back to 1979. We hold the distinction of being the very first manufacturer of thermal insulation materials north of the Yangtze River.
Today, our workforce represents a highly aligned, talented group with a shared vision of giving consistently first-class service to international industrial clients. Our team includes 8 professional engineers in our dedicated R&D Department, 6 professional international sales specialists, and over 230 highly skilled workers running our smart production lines.
Scientific advancements in polymeric structures for superior thermal resistance and fire mitigation.
By integrating nano-aerogel particles into closed-cell polyethylene (PE) and elastomeric rubber structures, our next-generation materials achieve a thermal conductivity ($\lambda$) of $\le 0.032$ W/m·K at 0°C. This molecular density design significantly diminishes heat transmission rates.
We are progressively transitioning our lines toward non-halogenated, zero-ODP (Ozone Depletion Potential), and extremely low GWP (Global Warming Potential) blowing agents. Our carbon-neutral polyolefin formulation complies with upcoming strict environmental safety laws.
Future engineering requirements place a heavy premium on toxicity indexes. Our technical roadmap utilizes modified aluminum trihydroxide and organophosphorus compounds to offer exceptional flame retardancy (Class 0 / Class 1) without toxic acid smoke gas release during fire emergencies.
Custom-engineered thermal insulation systems across demanding critical industries.
At ultra-low temperatures, standard insulation materials become brittle and lose physical integrity. Kingflex elastomeric insulation systems are chemically stabilized to handle extreme operating cycles down to -200°C (-328°F).
The completely closed-cell structure blocks any thermal bridging through moisture intrusion, eliminating ice accumulation on cold pipelines and preventing energy loss in liquid natural gas (LNG), liquid nitrogen systems, and medical-grade refrigeration units.
Modern commercial structures prioritize long-term thermal retention and indoor air safety. Our lightweight polyethylene insulation rolls and rubber foam sheets prevent duct condensation, which can foster structural mold development.
With high compression resilience (over 80%) and low moisture absorption, they absorb low-frequency vibration and fan noise, doubling as superior acoustic acoustic damping materials inside high-velocity mechanical ventilation chambers.
Providing cost efficiency and supply consistency through highly automated manufacturing processes.
Our Dacheng production facility utilizes 5 fully automated continuous extrusion assembly lines. By centralizing raw polymeric input mixing, precise thermodynamic foaming control, and instant thickness-monitoring laser matrices, we guarantee a standard production capacity of over 600,000 cubic meters annually.
This scale guarantees consistent, high-yield quality. It enables us to mitigate global raw material price fluctuations, passing the cost savings directly to overseas partners through competitive bulk pricing.
As a designated production supplier for the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry, our facility meets stringent quality standards.
Our commitment to global standards, audited and verified by top international testing labs.
Understanding customized dimension variations, volumetric calculations, and price determinants.
International insulation purchasing demands absolute precision. Standard dimensions must match localized piping standards (ASTM, DIN, JIS). At Kingflex, we offer detailed product optimization configuration options.
| Material Form | Material Base | Thickness Range | Internal Diameter (ID) / Dimensions | Density Range | Service Temperature |
|---|---|---|---|---|---|
| Insulation Sheet Roll | NBR / PVC / Polyethylene | 6mm - 50mm | Customized Width & Length | 40 - 55 kg/m³ | -40℃ to 105℃ |
| Insulation Pipe / Tube | NBR / PVC / Polyethylene | 9mm - 40mm | 6mm - 114mm | 40 - 55 kg/m³ | -40℃ to 105℃ |
| Cryogenic Insulation Roll | Modified Micro-Cellular Polyolefin | 6mm - 32mm | 1000mm / 1200mm Width | 50 - 65 kg/m³ | -200℃ to 105℃ |

Continuous communication and real-time updates keep projects moving forward smoothly.
Technical, administrative, and logistical insights directly from our engineering team.
A1: It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and acoustic sound insulation.
A2: Yes, our rubber foam insulation products are fire retardant, which meets the safety standards of building and industrial projects.
A3: Rubber foam is flexible, closed-cell, and moisture-proof, suitable for HVAC and building insulation. Rock wool is high-temperature resistant and fireproof, suitable for industrial high-temperature pipeline insulation.
A4: Yes, we support OEM services to meet different project needs.
A5: Our products have passed BS 476, CE, REACH, ROHS, UL94, ASTM and other international certifications, ensuring product quality and compliance with global standards.
A6: Yes, Kingflex products have full traceability back to their raw material batch records.
A7: We can produce sheet rolls ranging from 6mm to 50mm in thickness.
A8: When properly installed and maintained under standard operating conditions, the service life is about 10 to 15 years.
A9: Closed-cell configurations contain sealed gas pockets that prevent moisture migration. This design maintains low thermal conductivity ($\lambda$) under humid conditions and protects metal pipes from corrosion under insulation (CUI).
A10: PE insulation offers higher tensile strength, chemical resistance to solvents, and excels in underground piping. NBR/PVC rubber foam is more flexible, making it easier to install around complex fittings and elbows.
A11: Yes. We can pre-laminate reinforced aluminum foil (ALU), UV-resistant polymers, or tough fiberglass jackets to protect the insulation in outdoor or high-traffic environments.
A12: We roll and pack sheet insulation in plastic bags or cartons. Tubing can be packed nested inside larger diameters to maximize container volume and reduce ocean freight costs.
