Kingflex
Explore our leading collection of closed-cell elastomeric foam tubes, high-density acoustic barriers, and heavy-duty sheet rolls engineered for demanding industrial, HVAC, and building isolation programs.
Industrial piping systems, HVAC units, wastewater mains, and high-pressure steam distribution ducts are naturally prone to transmitting two forms of noise: airborne noise and structure-borne noise (vibration). Airborne noise travels straight through the hollow core of conduits, whilst physical pumps, fluid turbulence, and cavitation generate mechanical vibrations that move dynamically along the metal pipe wall.
High-density NBR/PVC elastomeric rubber foam functions as a viscoelastic damping layer. The complex open/closed structural dynamics inside Kingflex specialized foams act to dissipate wave energy. Sound waves strike the elastomeric boundary and are transformed into minute quantities of thermal energy through mechanical friction within the cellular lattice.
Additionally, applying soundproof insulation boards or adhesive-backed barrier wraps dramatically elevates the Transmission Loss (TL) value, conforming to stringent building noise criteria worldwide.
Our research and development program optimizes critical factors to secure superior performance indices:

Direct factory prices are determined by: 1. Raw chemical monomer prices (Nitrile Rubber & PVC resin markets); 2. Foam density settings (higher density requires more raw material per cubic meter); 3. Custom lamination layers (pure aluminum foil, woven glass scrims, or high-tack acrylic adhesives).
We provide mixed-container shipping configurations, specialized OEM branding, custom dimensional extrusion runs, and priority scheduling for key projects to support international distribution networks.
Our acoustic and thermal insulation systems are deployed across commercial facilities and industrial plants globally.
Scenario: High-velocity airflow in commercial air conditioning ducts generates airborne noise that travels into office spaces.
Solution: Wrapping ducting with Kingflex 25mm rubber foam sheets absorbs structural vibrations and limits acoustic transmission through walls.
Scenario: Fluid movement in wastewater lines creates high ambient noise levels in utility spaces.
Solution: Applying Kingflex NBR/PVC pipe sleeves reduces structure-borne vibrations, lowering overall noise levels.
Scenario: Low-temperature liquid lines require insulation that prevents condensation and limits sound transmission.
Solution: Kingflex cryogenic elastomeric systems control thermal transfer and reduce mechanical noise on process piping.
We maintain clear documentation and tracking for all international orders to support project scheduling and quality assurance.
Historically, acoustic insulation relied on mineral fibers or high-density wraps. While effective at dampening sound, these materials are susceptible to moisture absorption, which degrades performance and can cause corrosion under insulation (CUI).
Modern elastomeric NBR/PVC foam features closed-cell micro-cavities that isolate sound waves without absorbing moisture, maintaining thermal and acoustic performance in high-humidity environments.
By combining high-density elastomeric materials with aluminum cladding, modern insulation systems provide thermal control, fire safety, and sound absorption in a single application, reducing installation complexity for large projects.
At present, Kingflex operates 5 automatic assembly lines, delivering an annual capacity exceeding 600,000 cubic meters. These operations are structured to meet chemical and physical product specifications for public and industrial utility works.
Our systems conform to national standards under oversight from the Ministry of Energy, the Ministry of Electric Power, and the Ministry of Chemical Industry, ensuring consistent quality across product lines.
