Kingflex
Our top-tier elastomeric configurations designed to meet Central European acoustic absorption codes (MSZ standards) and building energy efficiency directives.
Hungary has positioned itself as the preeminent hub for the European electric vehicle (EV) supply chain, alongside a robust expansion of logistics parks, precision machinery, and food production plants. Heavy investments in industrial corridors such as Debrecen, Göd, and Győr have elevated the structural performance demands for noise suppression and thermal conservation inside advanced industrial facilities.
In accordance with OTÉK (Országos Településrendezési és Építési Követelmények) and local occupational health regulations, managing structural noise levels is mandatory. Standard factories and production cleanrooms are subject to severe regulations detailing maximum permissible sound propagation. This regulatory environment creates a critical need for high-performance sound absorption and thermal insulation materials.
Our elastomeric sound absorption panels and piping systems fully satisfy standard European structural fire behavior parameters (classified as B-s3, d0 according to EN 13501-1), ensuring streamlined engineering approvals across Hungarian municipalities.
In metropolitan Budapest, multi-story offices and historical property renovations require quiet ventilation networks. Closed-cell NBR/PVC panels prevent structural condensation while dampening high-frequency mechanical fan noise.
Advanced battery production requires extremely low humidity and cleanroom conditions. Our elastomeric materials prevent particulate shedding and feature anti-microbial surfaces, maintaining ISO-class cleanliness levels.
Supporting petrochemical plants along the Danube, our low-temperature systems provide structural thermal insulation down to -200°C, avoiding energy leakage and frost propagation.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research, development, and production center is situated in Dacheng, China—a well-known capital of green building materials. As an energy-saving, environmentally friendly enterprise, we concentrate on R&D, precision production, and global sales. Kingflex takes energy saving and consumption reduction as its core concept.
Established by the Jinwei Group, which possesses more than 40 years of manufacturing history, our legacy dates back to 1979. It was the first manufacturer of thermal insulation materials north of the Yangtze River. We provide complete solutions regarding thermal insulation by means of consulting, research and development, installation guidance, and post-sale service.
Our specialized team consists of 8 professional engineers in the R&D Department, 6 international sales consultants, and 230 skilled production technicians, ensuring stable material chemistry and reliable supply chain execution.
Our sound absorption and thermal barrier products are built using closed-cell elastomers (NBR/PVC) formulated to meet strict acoustic dampening thresholds and structural resilience values:
| Material Standard Property | Standard Specification (NBR/PVC) | European (EN) Test Standard Reference |
|---|---|---|
| Density Range | 40 - 55 kg/m³ | EN ISO 845 |
| Thermal Conductivity (λ) | ≤ 0.034 W/(m·K) at 0°C | EN 12667 / ASTM C518 |
| Moisture Resistance Factor (μ) | ≥ 10,000 (Closed-cell structure) | EN 12086 |
| Service Temperature Range | -50 °C to +105 °C (Standard) / Down to -200 °C (Cryogenic) | EN 14706 / EN 14707 |
| Fire Behavior Classification | Class B-s3, d0 (Self-extinguishing) | EN 13501-1 / UL 94 V-0 |
| Sound Transmission Class (STC) | Up to 32 dB (System Integrated) | ASTM E90 |
Traditional acoustic barriers use fiber structures which are prone to moisture absorption, reducing thermal performance. Our closed-cell rubber foam incorporates air chambers within the elastomer grid. This structure targets middle-to-low frequency resonance, typical of industrial pumps and air handling units (AHUs).
For cold-water installations in humid spaces, ambient moisture can condense on pipe surfaces, causing structural decay. Our high moisture resistance factor (μ ≥ 10,000) eliminates the need for additional vapor barriers, ensuring structural longevity.
Select standard and customized models engineered for building acoustic dampening, cryogenic lines, and industrial HVAC plants.
Optimized protective coatings and color-coded materials for specific architectural and plant engineering guidelines.
Located in the Dacheng green building materials industrial zone, our production base leverages concentrated supply chains for polymer raw materials, energy, and localized tooling. By operating five automated high-speed extrusion lines, we achieve an annual output exceeding 600,000 cubic meters. This scale provides a significant cost advantage over fragmented European fabricators.
For transport to Hungary and neighboring CEE countries, we coordinate with major shipping and rail routes. Orders are shipped from Tianjin port via direct ocean lines to European maritime hubs (Koper, Rijeka, or Piraeus), then moved inland via express rail directly to logistics yards in Budapest or Debrecen. This system maintains predictable delivery schedules for major construction projects.
