PIN flame retardant construction facer

Ahlstrom, launches non-halogenated FR facer paper for environmentally friendly fire safety in construction. Based in Finland, Ahlstrom is a global leader in combining fibres with sustainable materials. The facer paper uses patented PIN FR technology to ensure charring and self-extinguishing, meeting TAPPI T 461 (Technical Association of the Pulp and Paper Industry, flame resistance of paper and paperboard <1.6 mm thickness). Applied to insulation boards, it brings fire safety, mechanical strength and water resistance (reduced water absorption prevents delamination with weathering). It can be applied to aluminium foils, rigid insulation foams, stone- and glass-wool insulation panels and panels (OSB, MDF, HDF, particle boards). It can also be used in paint spray booths, filter systems, honeycomb structures, duct wrap,  decorative papers, wall coverings and other applications requiring fire safe materials. It is suited for processing by e.g. adhesive lamination, phenolic saturation, foil lamination, printing, slitting, sheeting, and is available in a range of colours and formats.
