Premium accessories designed for rapid installation, ensuring vapor-tight joints and thermal bridge mitigation on Swiss HVAC piping systems.
Switzerland has some of the most stringent building energy regulations in the world. With the enforcement of local Swiss cantonal energy regulations (MuKEn) and the widespread adoption of Minergie standards, HVAC systems, industrial processing facilities, and refrigeration loops are required to minimize heat loss and prevent energy dissipation. In this context, thermal insulation is no longer just a commodity—it is a critical engineering component.
From the pharmaceutical clusters in Basel to district heating systems in Zurich and cleanroom projects in Geneva, rubber foam insulation materials must satisfy severe parameters regarding fire classification (VKF standards), smoke index, low toxicity emission, and moisture protection. Our NBR/PVC closed-cell elastomeric accessories are engineered specifically to cater to these strict requirements, providing an impermeable barrier against vapor entry and structural energy leakage.
Engineered for low thermal conductivity, high moisture resistance, and extreme temperature durability across diverse Swiss applications.

| Service Temperature Range | -40°C to +105°C (Extended limit options down to -200°C) | EN 14706 / EN 14707 |
| Fire Reaction Classification | Class 1 / Class 0 (BS 476), VKF Fire Class 5.3 (Swiss compliant) | EN 13501-1 / VKF Guidelines |
| Compression Resilience | Over 80% recovery under standard deflection stress | ASTM D1056 |
| Chemical / Ozone Resistance | Excellent resistance to oil, grease, hydrocarbons, and UV radiation | ISO 1431-1 |
The uniform, closed-cell morphology blocks water vapor migration, completely eliminating risks of pipe corrosion under insulation (CUI).
Exceptionally low initial thermal conductivity remains stable for over 15 years, reducing maintenance cycle overheads.
Formulated with self-extinguishing flame retardants, ensuring low smoke density and toxicity during structural emergencies.
Kingflex Insulation Co., Ltd. is a professional manufacturing and trading combo for thermal insulation products. Our research development and production center is situated in the well-known capital of green-building materials in Dacheng, China. As an energy-saving, environmentally friendly enterprise, we concentrate on the research, development, production, and worldwide sales of advanced elastomeric solutions.
Established by the Jinwei Group, which possesses more than 40 years of industrial history (established in 1979 as the first manufacturer of thermal insulation materials north of the Yangtze River), Kingflex has grown to lead the global building materials industry. In operation, Kingflex takes energy saving and emission reduction as its core concept. We provide integrated solutions regarding insulation by means of consulting, research and development, custom production, detailed installation guidance, and dedicated post-sale service.
Ensuring compliance with international and Swiss quality, environmental, and toxicity thresholds.
Our dedicated R&D Department, staffed by eight professional senior chemical and mechanical engineers, consistently develops optimized formulations to improve insulation performance. Testing is performed in-house on critical features such as extreme low-temperature shrinkage, dynamic aging degradation, and flame spread parameters.
Kingflex products feature complete trace-codes to assure Swiss engineers of compliance. Our systems are officially certified under CE, BS 476, REACH, RoHS, UL94, and ASTM standards. This guarantees no outgassing of harmful halogens or volatile compounds, making them appropriate for healthcare, pharma, and public infrastructure spaces across Switzerland.

It is mainly used for HVAC ducts, air conditioning pipes, building thermal insulation, industrial pipeline cold insulation, district heating/cooling substations, and sound insulation. Its high water vapor resistance makes it particularly suitable for preventing condensation on cold lines.
Yes, our rubber foam insulation products are fire retardant. They are tested to international classifications (BS 476 Class 0, UL94 V-0) and align with VKF (Swiss Association of State Fire Insurances) guidelines, achieving self-extinguishing behavior and low smoke production suitable for public buildings.
Rubber foam is flexible, has a closed-cell structure, and is highly moisture-proof without requiring a separate vapor barrier. It is ideal for HVAC, refrigeration, and medium-temperature building applications. Rock wool is a fibrous material with high-temperature resistance and fire protection, making it suitable for industrial high-temperature pipelines (>150°C) and structural fire walls where vapor condensation is not the primary concern.
Yes, we support complete OEM services. We can customize internal diameters, thicknesses, densities, back-adhesive layers, protective outer foils, and pre-cut lengths to match the exact requirements of your specific engineering projects.
Our products have passed BS 476, CE, REACH, RoHS, UL94, and ASTM certifications. This ensures compliance with environmental, chemical restriction, and structural standards in Switzerland and the wider European market.
Yes, every manufacturing run is marked with factory tracking details, enabling full traceability from raw polymer compounding to final delivery. This is essential for verification in major Swiss public-sector tenders.
We produce sheet rolls in standard thicknesses from 6mm up to 50mm, allowing engineering teams to specify exactly the required thickness to prevent condensation based on local ambient dewpoint calculations.
When installed according to specifications, our rubber foam products have a service life of approximately 10 to 15 years, maintaining consistent thermal resistance and physical structure throughout that duration.
For standard formats, factory dispatch occurs within 14 to 20 days. Shipments are typically transported via sea freight to northern ports (e.g., Rotterdam or Hamburg) and then routed by rail directly to Swiss regional cargo hubs, ensuring efficient and timely delivery.
