Pipe Insulation Flexicell NBR 25mm ID x 13mm Wall x 2MTRS

is a flexible closed cell thermal insulation material for condensation control in air-conditioning, refrigeration and chilled water installa­tions. It is also suitable for reducing thermal losses in heating and plumbing sys­tems. The combination of its technical properties – a low thermal conductivity and a high resistance to water vapor transmission- and its competitive price makes it a cost-effective energy-saving solution.

ThePipe Insulation Flexicell NBR 25mm ID x 13mm Wall x 2MTRS has more range that covers the majority of pipe sizes used in these types of installations.



Flexicell is rated Class Oas per BS 476 Part 6 & 7 for spread of flame and fire propa­gation. It does not melt, nor drip when burning, therefore does not cause fire transfer. Low smoke density makes it a safer option.



Flexicell NBR has a unique closed cell stru­cture, which offers the material a very good and stable thermal performance through a low Lambda p,) value



Flexicell NBR is CFC & HCFC free, fiber free, dust free and resistant to mold and fungi growth. It has very low ODP (Ozone Depletion Potential) and GWP (Global Warming Potential)



Flexicell NBR is compounded to achieve a high water vapour diffusion resistance through its closed cell structure and outer dense skin. This helps maintaining a steady thermal performance and a long service life.



Flexicell NBR is quick and easy to install due to its high flexibility, dimensional stability and smooth surface skin. It can be applied on pipes, ducts and tanks.




Brief description:

Highly-flexible, closed-cell insulation material with high water vapor diffusion resistance and low thermal conductivity. Material: Elastomeric foam based on synthetic rubber with density between 60-70 Kg/m3

Self-adhesive coating: Pressure-sensitive adhesive coating on modified acrylate basis. Covered with polyethylene foil. Applications: Insulation / protection for pipes, air ducts, vessels (incl. elbows, fittings, flanges etc.) of air-conditioning / refrigeration and process equipment to prevent condensation and sea energy.
