Description
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.
FIRE RESISTANCE
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.
EXCELLENT THERMAL EFFICIENCY
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
ENVIRONMENTALLY FRIENDLY
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)
HIGH WATER VAPOR DIFUSSION RESISTANCE
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.
EASE OF INSTALLATION
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.
TECHNICAL DATA
