Explore our factory-direct selection of high-performance closed-cell insulation materials engineered for HVAC, piping, and industrial systems.
In high-performance thermal insulation systems, the physical sheets and tubes are only as reliable as the joints that connect them. Sourcing the correct Insulation Glue is not merely a purchasing detail—it is the foundation of preventing vapor barrier breach and structural thermal failure.
Closed-cell elastomeric rubber foam (NBR/PVC) prevents thermal energy transfer by trapping dry air inside millions of microscopic bubbles. However, if seams, joints, or endings are glued using inferior adhesives, moisture from ambient air will inevitably migrate through the seams. Once water vapor penetrates the barrier, it condenses on cold pipe surfaces, leading to Corrosion Under Insulation (CUI), massive thermal losses, and structural mold issues.
Professional adhesive formulations are designed to:
More than 40 years of pioneering green building and thermal insulation innovation.
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 comprehensive solutions regarding insulation by means of expert consultation, research & development production, installation guidance, and dedicated post-sale services to lead the development of the global building materials industry.
Kingflex was established by the Jinwei Group, which boasts more than 40 years of history. Jinwei Group, established in 1979, was the first manufacturer of thermal insulation materials north of the Yangtze River. This long-standing industry presence underscores our deep expertise and commitment to quality.
Our employees are amazing in their own right, but together they are what makes Kingflex such a fun and rewarding place to work. The Kingflex team is a tight-knit, talented group with a shared vision of giving consistently first-class service to our clients.
Kingflex has eight professional engineers in our R & D Department, 6 professional international sales specialists, and 230 dedicated workers in our production department. This human-centric structure ensures that from raw materials to bulk shipping, every detail is overseen by experienced specialists.
How our localized integration and raw material access translate into global cost savings and reliability.
Operating out of Dacheng, the undisputed green-building material capital of China, gives Kingflex a raw materials advantage. Nearby chemical refinement plants keep monomer costs stable, assuring cost efficiency for rubber polymer blends and insulation glues.
With an export footprint spanning over 66 countries in the past 16 years, our transport pathways, port integrations, and custom declarations are fully optimized. We manage bulk custom requests effortlessly to avoid supply chain disruptions.
Our 5 automated assembly lines allow us to scale production up to 600,000 cubic meters annually. Whether it is standard construction runs or massive cryogenic pipeline systems, our lead times remain highly predictable.
Technical details for Kingflex standard black rubber foam sheet rolls and pipes.
Our sheet rolls are optimized for broad-surface installations like central air conditioning ducts, mechanical room walls, and wide process vessels.
Specially extruded for copper pipelines, steel pipe loops, and industrial steam or cold water systems.
Ensuring our products conform to stringent building and environment standards globally.
Our commitment to quality is validated by international standards bodies. Kingflex rubber foam insulation materials and adhesives are thoroughly tested for fire ratings, toxicity, chemical migration, and aging profiles.
We boast full traceability for all batch runs. Whether you are building under European Union directives or American standards, our certifications assure quick project sign-offs.
Addressing global procurement realities: how we support local distribution and supply standards.
Global procurement teams in North America, Europe, and the Middle East require more than just products; they require logistical compatibility. Kingflex offers extensive support for localized project specifications:
Modern building regulations (such as LEED or BREEAM) enforce strict limits on volatile organic compounds. Our chemical department manufactures low-VOC and solvent-free insulation glues that comply with local indoor air quality standards.
From cryogenic liquid storage tanks in the Baltic to commercial HVAC loops in the Arabian desert, our formulas are adapted to perform reliably in extreme temperature swings.
Liquid adhesives are sensitive to transport temperature shifts. We offer specialized bulk containers with thermal linings, preventing curing during ocean transit and ensuring ready-to-use delivery.
Transparent partnerships and verified feedback from our global network of distributors and contractors.
Kingflex is dedicated to providing integrated solutions of thermal insulation, cold insulation, and noise reduction for buildings and industrial systems. We aim to support our clients with a full set of energy-saving solutions.
Over the years, our customer relations have flourished because of open and prompt communications. Our technical support team works closely with project estimators to determine the correct ratio of glue to insulation foam, saving materials and costs.
Where Kingflex products are actively safeguarding energy resources.
Anti-condensation and structural insulation for central ventilation lines in five-star hotels, healthcare facilities, and shopping centers. Eliminates acoustic transmission from high-volume air handlers.
Protecting low-temperature pipelines in LNG transport, cryogenic chemical refineries, and pharmaceutical clean rooms. Ensures continuous operations without icing.
Wrapping steam lines, chemical process loops, and massive storage tanks to minimize heat loss, improving overall factory thermodynamic yield.
Decarbonization, eco-friendly solvents, and advanced polymer crosslinking.
Traditional adhesives depend heavily on volatile organic solvents like toluene. The industry is rapidly shifting toward water-borne acrylic or polyurethane dispersions. While slightly slower in cure speed, they offer superior safety profiles and zero emissions. Kingflex is testing new hybrid formulas that balance fast tack times with environmental safety.
By refining the vulcanization and blowing phases of NBR/PVC foams, our engineering team is lowering the thermal conductivity coefficient (λ) closer to 0.032 W/(m·K) at 0°C. This allows thinner insulation jackets to match the performance of bulkier traditional systems, lowering installation costs.
Technical clarifications on elastomeric rubber foam insulation and corresponding adhesive applications.
A1: It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its closed-cell matrix prevents moisture ingress, making it highly effective for cooling and refrigeration pipe insulation where condensation is a constant challenge.
A2: Yes, our rubber foam insulation products are fire retardant, which meets the safety standards of building and industrial projects. They possess self-extinguishing properties, generate low smoke emissions, and hold key fire-safety credentials like BS 476 and UL 94.
A3: Rubber foam is flexible, closed-cell, and highly moisture-proof, making it suitable for HVAC, chilled water piping, and architectural insulation. Rock wool is high-temperature resistant and fireproof, making it ideal for high-temperature industrial pipelines, boilers, and heavy fire containment zones.
A4: Yes, we fully support OEM and ODM services. We can customize the inner diameters, thicknesses, densities, sheet roll widths, backing adhesives, and technical ratings to suit specific engineering profiles.
A5: Our products have passed BS 476, CE, REACH, RoHS, UL94, ASTM, and other international certifications, ensuring reliable product quality and compliance with global construction and environmental standards.
