Kingflex
Engineered for extreme performance in dry desert heat, high humidity zones, and demanding industrial applications.
Israel's geographic diversity creates a demanding environment for industrial and commercial building systems. From the humid, saline marine air of the coastal plains (Tel Aviv, Haifa) to the dry, searing desert heat of the Negev (Beersheba) and the high altitude of the north, thermal insulation systems must satisfy rigid performance profiles. Rapid shifts between seasonal ambient extremes demand structural and insulation materials that do not degrade or fail prematurely.
Local industrial operations demand closed-cell elastomeric rubber foam sheets with exceptional resistance to water vapor transmission ($\mu \ge 10,000$) and highly stable thermal conductivity ($\lambda \le 0.034\text{ W}/(\text{m}\cdot\text{K})$ at $0^\circ\text{C}$). Without these safeguards, systems encounter high rates of condensation, moisture pooling, and structural corrosion beneath the insulation layer (CUI).
As Israel pushes forward with advanced commercial infrastructure, seawater desalination terminals, cleanrooms for semiconductor design, and pharmaceutical laboratories, the need for clean, non-fibrous, and highly fire-retardant thermal insulation is more vital than ever before.
Ensuring complete vapor barrier continuity to block chloride-driven corrosion on underlying copper and steel piping networks.
Meeting local structural safety protocols with certified flame-retardant, self-extinguishing elastomeric structures.
Supplying fiber-free, VOC-compliant insulation sheets safe for cleanroom ceilings, electronic fabs, and biomedical laboratories.
Premium low-temperature resilient formulations designed to maintain flexibility and thermal resistance under severe conditions.
The evolution of NBR/PVC elastomeric foam chemistry toward net-zero environmental impact and smart monitoring capabilities.
In step with global sustainability developments and the green building initiatives under the Standards Institution of Israel (SII) framework, Kingflex is leading the transition to next-generation raw material processing. Our research and development department works actively on three specific engineering frontiers:
Traditional blowing agents are being replaced with advanced, eco-friendly alternatives that yield zero Ozone Depletion Potential (ODP) and negligible Global Warming Potential (GWP). By modifying the micro-cellular matrix structure at a molecular level, we maintain the optimal density threshold (40-55 kg/m³) while improving long-term material stability and eliminating outgassing concerns in confined spaces.
Condensation on structural components leads directly to microbial growth. Our latest rubber foam formulations incorporate stable, non-leaching antimicrobial additives during the compound blending stage. This protects HVAC insulation against mold, mildew, and bacterial colonies, safeguarding Indoor Air Quality (IAQ) inside hospitals, administrative buildings, and schools across Israel.
To satisfy challenging acoustic and physical protection demands, Kingflex manufactures multi-layered hybrid systems. These combine standard NBR/PVC closed-cell foam sheets with high-density mass loaded vinyl (MLV) barriers and reflective aluminum foil outer layers. The resulting composites provide superior sound damping alongside robust resistance to mechanical abrasion, punctures, and intense solar UV radiation.

As international supply chains face ongoing shipping and logistics challenges, procurement professionals in Tel Aviv, Haifa, and Ashdod require absolute supplier stability. Kingflex offers direct manufacturing depth with an annual capacity of over 600,000 cubic meters, powered by five fully automated assembly lines in the green-building materials center of Dacheng, China.
Our Factory 4.0 production framework utilizes automated raw material dosing, real-time computerized extrusion monitoring, and continuous density grading. This guarantees that every shipment of rubber foam sheet rolls maintains consistent thickness, uniform closed-cell structure, and predictable thermal insulation performance.
By bypassing middle-tier distributors and buying directly from our production base, Israeli industrial buyers optimize procurement costs and ensure direct product traceability from raw materials to final worksite installation.
Direct Factory Control: 600,000 m³ capacity across 5 modern automatic production lines.
Full Batch Traceability: Strict quality checks, batch codes, and complete certification records.
Tailored OEM Capabilities: Customized density, dimensions, adhesives, and protective laminates.
A premier manufacturing and trading combo, delivering advanced thermal, cold, and acoustic insulation solutions globally.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our R&D and production departments are located in Dacheng, China, the well-known capital of green building materials.

Expert answers about the technical properties, chemical composition, and performance profiles of Kingflex elastomeric insulation products.
It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, and sound insulation. Its closed-cell structure prevents moisture ingress, making it ideal for systems prone to condensation, such as chilled water pipelines and air distribution networks.
Yes. Our rubber foam insulation is fire retardant and meets international and local standards, including Class 0 and Class 1 ratings (BS 476 Part 6 & 7), ASTM E84, and UL94 V-0. When exposed to flames, it is self-extinguishing and produces minimal smoke, satisfying local fire safety requirements for public and commercial buildings.
Rubber foam is flexible, closed-cell, and moisture-proof, suitable for HVAC and building insulation. It does not require an additional vapor barrier and prevents condensation on cold lines. Rock wool is high-temperature resistant and fireproof, suitable for industrial high-temperature steam pipelines. However, rock wool has an open-cell structure that can absorb moisture if its vapor barrier is damaged, which may lead to corrosion under insulation (CUI).
Yes. We support full OEM and ODM services. We can customize sheet thicknesses (6mm to 50mm), pipe inner diameters (6mm to 114mm), density levels, and add specialized backings such as self-adhesive layers, protective aluminum foil, or mass-loaded vinyl coverings for demanding acoustic applications.
Our products have passed BS 476, CE, REACH, ROHS, UL94, ASTM, and ISO 9001 certifications. This guarantees that our materials comply with global chemical safety guidelines (like REACH/RoHS) and fire safety regulations, ensuring smooth approval processes with project engineers and local authorities.
Yes. Every batch of Kingflex rubber foam insulation is traceable. We apply detailed production codes to our packaging and documentation, allowing us to trace products back to the raw materials, specific assembly lines, and QA test records. This ensures high accountability for large infrastructure projects.
We produce single-layer rubber foam sheets from 6mm up to 50mm in thickness. For projects requiring greater thermal resistance, multiple layers can be built up using compatible, high-performance adhesives without affecting the system's overall vapor barrier performance.
Under normal operating conditions and when installed according to manufacturer guidelines, Kingflex rubber foam insulation has a service life of 10 to 15 years. For outdoor installations, applying a UV-resistant protective cladding or coating will extend the material's lifespan and prevent weathering.
