New applications for PIN flame retardants

Sabyasachi Gaan, EMPA Switzerland, presented testing of PIN FRs in reactive extrusion of polyamide. An oligomeric phosphorus PIN flame retardant was embedded in polyamide, by reaction of a phosphorylated vinyl monomer (DVPPO) with the cyclic amine (piperazine) in extrusion of polyamide polymer to fibres, so embedding the resulting phosphorus-nitrogen macromolecules in the polyamide matrix.

EU “chemicals restrictions roadmap”

The European Commission has published a “roadmap” of assessment priorities for chemicals for possible restrictions. The Commission states that the roadmap “prioritises group restrictions for the most harmful substances to human health and the environment” as set out in the Green Deal Chemicals Strategy for Sustainability, and will become the basis for multiannual planning under REACH, to be regularly reviewed to ensure flexibility and progress.
