Explore our flagship ranges manufactured with strict compliance to global thermal, acoustics, and fire standards.
Established by the Jinwei Group, which holds a rich historical background spanning over 40 years, Kingflex Insulation Co., Ltd. stands as a premier manufacturing and trading combo for high-grade thermal and acoustic insulation products. Our parent group, established in 1979, pioneered the production of thermal insulation materials north of the Yangtze River.
Operating out of the globally acknowledged capital of green-building materials in Dacheng, China, Kingflex integrates cutting-edge energy-saving technologies with green environmental research. We offer system-level consulting, research and development, custom manufacturing, installation assistance, and extensive post-sales logistics.
Our roots date back to 1979. Over decades of industrial progression, we have elevated our material formulations from basic thermal barriers to complex multi-layered acoustic systems. With our proprietary elastomer compounding, we prevent structural condensation while dampening airborne and structure-borne sound wave transfers.
Today, Kingflex acts as a key national vendor for national power grids, chemical giants, and commercial infrastructure, maintaining compliance with both domestic and major international building safety authorities.
Our intelligent production base guarantees high volume stability, precision thickness execution, and immediate international dispatch.
Kingflex operates 5 large automatic continuous assembly lines. Our smart raw material mixing systems maintain consistency in material density and cell structure, keeping closed-cell counts above 98% across batches.
With an annual output exceeding 600,000 cubic meters, we maintain strategic inventory for major HVAC and cryogenic configurations. This helps reduce lead times for key projects in the EMEA, APAC, and Americas regions.
Approved and recognized by the Ministry of Energy, Ministry of Electric Power, and Ministry of Chemical Industry, Kingflex supplies materials for heavy industrial construction projects worldwide.

A scientific approach to cellular structures: optimizing Sound Transmission Class (STC) and Noise Reduction Coefficient (NRC).
Kingflex has 8 professional R&D engineers who focus on improving physical sound dampening and thermal properties. Acoustic insulation works by converting sound energy into trace heat through mechanical friction within the rubber polymer matrix.
By combining open-cell sound absorption layers with high-density closed-cell moisture barriers, we prevent typical system compromises. Open-cell configurations capture mid-to-high frequency airborne noise (such as equipment hums), while the closed-cell structure manages low-frequency vibration and limits moisture ingress.
Our current research focuses on hybrid aerogel-rubber composites, aiming to reduce product thickness while maintaining standard acoustic decibel drops.
Different environments require custom configurations. Kingflex designs specific solutions for HVAC, industrial complexes, and extreme cryogenic setups.
Commercial ventilation systems can carry fan noise throughout a building. Installing Kingflex open-cell rubber liners inside HVAC ducts helps absorb airborne noise, keeping indoor environments quiet.
Benefits: Fire-safe construction, low VOC emissions, and protection against duct condensation.
High-pressure steam pipes and chemical transport channels generate structural vibration and high heat. Our high-density NBR/PVC sheets absorb vibrations and resist chemicals, preventing CUI (Corrosion Under Insulation).
Benefits: Stable under high mechanical pressure, chemical resistance, and long service life.
Operating down to -200°C requires specialized materials. Kingflex Cryogenic elastomeric formulations maintain flexibility at low temperatures, preventing thermal stress cracks and controlling noise from high-pressure piping.
Benefits: Prevents vapor ingress, handles temperature transitions, and reduces vibration.
Our products are used in rail transit systems, hospitals, shopping malls, defense facilities, and chemical storage plants. With 16 years of export history, we customize materials to comply with regional building code requirements.

Used for wide-surface application on air ducts, wall systems, and large storage containers.
For plumbing lines, chilled water pipes, and chemical manufacturing process pipelines.
Our materials undergo rigorous testing by third-party laboratories to ensure safety in various environments.
Kingflex products comply with critical international testing parameters. Our fire performance ratings meet BS 476, CE, REACH, RoHS, UL94, and ASTM requirements.
This compliance is crucial for installations in hospitals, transit hubs, and corporate offices, ensuring that our insulation maintains fire protection and low smoke emission levels.
Additionally, our international logistics department coordinates with freight forwarders to manage custom clearing documentation, helping projects stay on schedule.
Our sales and support teams communicate with buyers worldwide, providing updates on specifications, customs clearance, and delivery schedules.

It is primarily used for commercial and industrial HVAC ducts, refrigeration/air conditioning piping, thermal building insulation, and cold pipeline systems. It also dampens sound, absorbing machinery hums and reducing structure-borne noise.
Yes. Kingflex rubber foam is designed with fire-retardant additives. It complies with major international fire safety standards, including BS 476 Part 7 (Class 1) and UL94, self-extinguishing without generating burning droplets.
Rubber foam features a flexible, closed-cell structure that resists water vapor, making it ideal for HVAC, cold systems, and preventing CUI. Rock wool is a fibrous material suited for high-temperature applications (up to 1000°C) and acoustic barrier walls.
Yes. We support custom manufacturing (OEM/ODM). We can adjust product dimensions, wall thicknesses, and densities, and add protective cladding (like aluminum foil) to meet specific architectural or industrial project specifications.
Our insulation products hold certifications like BS 476, CE, REACH, RoHS, UL94, and ASTM. This documentation supports the quality audit and compliance processes required for global projects.
Yes. Our ERP system tracks each manufacturing batch from raw polymer mixing and curing to vulcanization, packaging, and shipping. This helps ensure quality consistency across all shipments.
Our automated continuous calendering lines produce thicknesses from 6mm up to 50mm, ensuring uniform material consistency across the entire width of the rolls.
Under normal operating conditions and when installed correctly on systems within our specified temperature limits (-40℃ to 105℃), the material typically has a service life of 10 to 15 years.
