Armacell Tuffcoat foamed nitrile rubber laminated with a PVC coating, for protection against impact damage

 

Armaflex Tuffcoat comprises of foamed nitrile rubber laminated with a Tuffcoat PVC coating, designed for protection against impact damage. According to the company, the product is suitable for both above and below ground installations including mains cold water and ground source heat pump pipework to prevent freezing.

The tube version of the product has now been redesigned so that around a quarter of the Tuffcoat PVC covering is left un-adhered to the Armaflex insulation tube. This un-adhered section of the covering has a self-adhesive backing with protective peel off paper sheet for removing and fixing down onto the Armaflex insulation once the tubes are installed onto pipework.

The protective paper on the self-adhesive backed section can then be peeled off and the Tuffcoat film sealed in place down over the glued seam. The un-secured piece of the Tuffcoat film overlaps the circumference of the tube to provide additional integrity against moisture ingress at the tube seam.                                                                                                                       

The Armaflex Tuffcoat insulation tubes are now supplied in one-metre lengths rather than two-metres. This change is to facilitate both easier and quicker installation by simplifying handling of boxes onsite, said the company, and when sliding the tubes onto new pipework or slitting and re-sealing tubes onto existing pipework applications.

The new tube design leaves a short piece of the Armaflex insulation material uncovered at each end. This allows for wet sealing the tubes under compression at longitudinal butt joins, designed to ensure that a vapour tight seal is achieved on refrigeration, cold services and outdoor applications.
