ARMACELL ONEFLEX pipe rubber insulation

Armacell OneFlex synthetic rubber pipe insulation is a professional solution for heating, ventilation, air conditioning, and refrigeration systems. Made from flexible closed-cell elastomeric foam, this material ensures minimal heat loss, completely prevents condensation, and protects pipelines from corrosion.

Armacell OneFlex elastomeric pipe insulation is manufactured according to strict European EN 14304 standards and features a highly flexible structure with evenly distributed closed cells. Unlike open-cell insulation materials, it does not absorb moisture and maintains its performance properties for decades. Thanks to its high elasticity, the tubes are easily installed on straight sections, bends, and fittings without the need for additional cuts, significantly speeding up the installation process.

Advantages of Elastomeric Foam Pipe Insulation

Armacell OneFlex rubber pipe insulation offers several key benefits. First, its low thermal conductivity ($\lambda d \le 0.035$ W/(m·K) at 0 °C per EN ISO 13787) allows for a significant reduction in energy consumption for both heating and cooling systems. Second, its high water vapor diffusion resistance ($\mu \ge 7000$) eliminates condensation even on cold pipes where the medium temperature is below the dew point.

The material remains flexible at temperatures ranging from –40 °C to +120 °C, without cracking or deforming. Additionally, it reduces noise from flowing liquids, has a Fire Class E rating (reaction to fire per EN 13501-1), and is resistant to oils, aggressive environments, and mechanical impacts. This makes it an ideal choice for modern engineering systems where durability and safety are paramount.

Applications of Rubber Pipe Insulation

Armacell OneFlex is used to protect pipelines in various engineering systems. Specifically, elastomeric foam insulation is applied in the following areas:

• Heating and hot water supply systems;
• Cold water supply mains;
• Air conditioning and ventilation ductwork;
• Refrigeration units and cooling systems;
• Process piping at industrial facilities.

Due to its elasticity and tight fit to the pipe surface, rubber insulation effectively prevents heat loss and reduces the risk of moisture formation on pipelines.

Design and Supply Format

The SANSTORE online store offers rubber insulation in tube format, which is the most convenient form for installation. Insulation elements come in either pre-slit or unslit (solid) forms and are easily installed on pipes of various diameters.

This design significantly simplifies mounting and reduces installation time. Furthermore, elastomeric foam for pipes maintains flexibility even at low temperatures, making it easy to work with in various climatic conditions.
