Gérard Lips, BASF (pinfa member), underlined that flame retardants must enable product fire safety requirements whilst also respecting objectives for environmental and health safety and for recyclability. For films used in the construction industry, they must also offer durability (ranging from few years up to 15 years), high flow processing (thin film extrusion) and not reduce material performance characteristics (elongation at break).
He presented developments in PIN FRs polypropylene and polyethylene films, for applications such as protective weather wraps for vehicles, protective films for construction sites, artificial grass, offering light stability and pigment compatibility, low processing corrosivity and no processing odour, recyclability and effective fire performance achieved by both runaway effect in condensed phase and release of a non-halogen radical scavenger in the gas phase.
