Kingflex Insulation Co., Ltd. is a premier manufacturing and trading conglomerate specializing in high-efficiency thermal insulation products. Our cutting-edge research, development, and advanced manufacturing divisions are situated in Dacheng, China—a globally recognized hub for eco-friendly building materials. At Kingflex, we operate with a singular core directive: to drive down energy consumption and carbon footprints through innovations in materials science.
We provide comprehensive system insulation engineering support, spanning diagnostic consultation, bespoke R&D, product manufacturing, on-site installation guidance, and robust post-installation services. Through these integrated efforts, Kingflex leads the advancement of global insulation solutions in commercial HVAC, industrial piping, and ultra-low temperature cryogenic logistics.
Established as a strategic venture by the renowned Jinwei Group, Kingflex inherits over 40 years of specialized manufacturing experience. Jinwei Group, founded in 1979, was the pioneer thermal insulation material manufacturer north of the Yangtze River, defining industry standards for generations.
Evaluating elastomeric foam insulation on a total cost of ownership (TCO) basis requires understanding the structural variables that impact unit cost, shipping volume, and long-term operating efficiency.

Pricing is governed by polymer raw material costs (NBR/PVC), density optimization metrics, fire-retardant chemical dosing, and secondary laminations (such as UV-resistant aluminum foil or self-adhesive backings).
Because insulation is lightweight and high-volume, our factory packs and compresses sheet rolls systematically, maximizing container fill rates and significantly lowering ocean freight costs per cubic meter.
Every shipment comes with raw material and manufacturing run logging, allowing industrial engineers to trace compliance history back to the production batch for QA audits.
Kingflex utilizes automated, continuous production lines that keep cell structures consistent, output high, and manufacturing emissions low.
Integrating chemical engineering expertise with continuous extrusion-foaming technology to deliver stable insulation performance.
Provides an annual manufacturing capacity exceeding 600,000 cubic meters. Automated processes eliminate the density and dimensional variances common to batch manufacturing.
Officially vetted and designated as a critical energy-saving supplier for major industrial expansions managed by the Ministry of Energy and Ministry of Chemical Industry.
Our permanent engineering team continuously refines polymer cross-linking and flame-retardant chemistry to meet evolving regional fire and toxicity regulations.
Direct supply agreements with chemical producers prevent supply chain disruptions, keeping our lead times stable even during volatile global market conditions.
From cryogenic gas transport to commercial HVAC installations, Kingflex systems are engineered for long-term thermal efficiency in demanding environments.
Ultra-low temperatures down to -196°C require specialized insulation to prevent boil-off and piping damage. Kingflex cryogenic systems combine high vapor barrier ratings with elasticity to absorb thermal contraction stresses, keeping piping networks intact and operating efficiently.
Our elastomeric insulation sheets and pre-formed tubes prevent condensation in humid conditions, which protects surrounding building structures and ceiling assemblies. The material is dust- and fiber-free, helping maintain indoor air quality in schools, hospitals, and commercial offices.
Elastomeric NBR/PVC structures provide reliable thermal protection for chemical plants, refineries, and food processing lines. The closed-cell matrix prevents moisture ingress, reducing the risk of Corrosion Under Insulation (CUI) to extend the lifespan of carbon and stainless steel piping.
Our research focus goes beyond current standards, targeting halogen-free formulations, enhanced thermal resistance, and bio-based polymers to support global decarbonization.
By eliminating chlorine and bromine additives from our NBR/PVC polymers, we produce materials that generate minimal smoke and zero acidic fumes during a fire, meeting strict rail, transit, and cleanroom air quality specifications.
We are developing hybrid materials by embedding silica aerogels into the cell walls of elastomeric foam, reducing thermal conductivity to less than 0.030 W/m·K and enabling thinner profiles in space-constrained installations.
Our research team is replacing petroleum-derived plastics with plant-derived plasticizers and bio-rubbers, reducing the carbon footprint of our insulation products while maintaining flexibility and moisture resistance.
Our products undergo third-party testing to ensure they comply with building codes and fire safety regulations in Europe, North America, and the Asia-Pacific region.
Kingflex materials are certified by leading global classification societies and international testing laboratories. We maintain compliance with standards such as BS 476 (Class 0 and Class 1), CE EN 14304, REACH, RoHS, UL 94 (V-0 rating), and ASTM C534.
These certifications verify our insulation’s flame-spread indexes, smoke density ratings, and low chemical emission levels. This makes Kingflex products suitable for airports, transit terminals, high-density residential buildings, and clean industrial facilities.
Our quality assurance program extends from factory mixing to on-site delivery, ensuring material performance remains consistent at every step.
We work directly with engineers, procurement departments, and distributors worldwide. Through open project logging and digital messaging, we verify technical specifications, confirm order statuses, and coordinate shipping schedules to keep projects on track.
