Advantage of Careflex-NBR Insulation
Low thermal conductivity, which makes it highly effective in the insulation of cooling & heating Systems.
Light weight and flexible thus making installation very easy and speedy ultimately saving time & cost.
The improved u value in closed cell structure makes and impermeable layer which is in itself a good vapour barrier.
It is suitable for application within th temperature range of -40C to +105C
The meterial has been specially compunded to be self - ectinguishing in nature.
It is Free of CFC, HCFC, Fiber. And it does not cause skin allergy.
Less Thickness is required in specifiying Careflex-NBR insulation in comparison to other meterials due to very low thermal conductivity & better resistance to moisture.
"Careflex"also retard heat loss in hot water plumbing and solar heating systems. It also protects piping by acting as a vibration damper and giving protectionagainst corrosion from atmospheric environment.
Wide range of tubes & sheets is available to ideally suitable for insulation of different pipe size, air ducts and large surface areas e.g.tanks or irregular shaped vessel.
UV RAYS PROTECTION: It is strongly recommended to protect outdoor isulation from uv rays & weather by using Careflex coating paint or aluminium sheet covering or any equivalent UV resistant finish.
