Fouad Laoutid, Materia Nova, Belgium, outlined a number of research areas looking at PIN flame retardant solutions for polylactides (PLA), using bio-based flame retardants or phosphorus-based protective coating by plasma enhanced chemical vapour deposition (PECVD) of phosphorus compounds onto polyester fibres. The plasma deposition achieved self-extinguishing in PLA woven fibre, with very thin deposit layer (<1µm), without deteriorating color or feel. He also presented new results on the preparation of inherently flame retardant PLA obtained by the insertion of DOPO based molecules (phosphorus containing) into the PLA polymer chain by ring opening polymerization and reactive extrusion. This phosphorylated PLA shows V0 classification at UL-94 even when blended with virgin PLA (50/50 wt/wt).
