Explore our primary array of high-density elastomeric and open-cell insulation systems specifically configured to withstand high humidity and structural vibration.
Indonesia is undergoing an unprecedented wave of industrial growth, urbanization, and infrastructural development. Heavy machinery, central air conditioning (HVAC) systems in commercial complexes, data centers in West Java, and marine vessels across Batam all generate severe environmental and mechanical noise. To protect operational reliability and comply with strict national health and safety standards, the application of highly scientific sound absorption insulation is crucial.
Operating in a tropical maritime climate poses significant architectural challenges. High ambient temperatures exceeding 35°C combined with relative humidity levels constantly hovering between 80% and 95% create a severe breeding ground for mold, mildew, and corrosion under insulation (CUI). Traditional fibrous insulation materials are highly susceptible to moisture absorption, leading to thermal degradation and structural decay. Our closed-cell and engineered open-cell elastomeric rubber insulation systems are explicitly synthesized to prevent water vapor intrusion while delivering exceptional sound transmission loss properties.
The sound absorption capabilities of Kingflex elastomeric materials depend heavily on their internal micro-structural geometry. By utilizing a proprietary blend of Nitrile Butadiene Rubber (NBR) and Polyvinyl Chloride (PVC), we create an open-cell and semi-open cell matrix that acts as a sound energy trap. When sound waves collide with the elastomeric structure, the air particles vibrate inside the tortuous micro-pores, turning sound energy into thermal energy through viscous friction.
Furthermore, our NBR/PVC formulation features high density (40-55 kg/m³) and extreme flexibility, enabling excellent structural vibration damping. This is vital for industrial machinery jackets, engine rooms, and heavy ventilation ducts where structural vibration often converts into airborne noise.
With 5 highly advanced automatic continuous extrusion production lines, Kingflex achieves an annual capacity exceeding 600,000 cubic meters. This massive manufacturing volume guarantees price stability and prompt order fulfillment, shielding our customers from supply chain interruptions.
Our strategically located facility in Dacheng, the green-building materials center in China, enables direct logistics connections to major ports like Tianjin and Qingdao. We offer swift, dependable shipping services to major Indonesian logistics hubs, including Port of Tanjung Priok (Jakarta), Port of Tanjung Perak (Surabaya), and Batam Free Trade Zone. We manage all export customs clearance, shipping arrangements, and quality certificates to provide a hassle-free purchasing process for Indonesian contractors and industrial clients.
Industrial chilling units and high-velocity HVAC ducts in Bekasi and Cikarang tech hubs require high-density thermal and acoustic insulation to control room acoustics and prevent condensation drip.
Refinery complexes in East Kalimantan and Sumatra use our heavy-duty insulation pipes to achieve thermodynamic process control and mitigate loud fluid-flow acoustics.
For major residential, corporate, and hospital skyscrapers across Jakarta and Surabaya, our Class 0 NBR foam controls localized noise within HVAC ductworks and plumbing shafts.
At Kingflex, our team combines talent and experience to deliver unmatched insulation solutions. Our division is supported by 8 veteran research engineers in our R&D Department, 6 international trade specialists, and 230 manufacturing staff.
Our R&D team continuously conducts acoustic testing and thermal simulation programs to enhance the performance of NBR/PVC matrices under high-humidity, high-temperature settings. By partnering with Kingflex, you access a full spectrum of energy conservation engineering, installation support, and responsive after-sales service.
In modern construction and industrial engineering, product compliance is non-negotiable. Our acoustic and thermal insulation systems are fully verified to comply with critical global standards, ensuring safety, efficiency, and reliability for large-scale projects in Indonesia.
Every batch of our NBR/PVC foam insulation undergoes intensive laboratory testing to assure complete traceability. Our systems conform to BS 476 (Class 0 and Class 1 fire rating), CE, REACH, ROHS, UL94, and ASTM requirements. This guarantees that our products do not release hazardous fumes, restrict flame spread, and provide stable thermal and acoustic performance throughout their lifespan.
