Halogenated FRs in China recycled plastics
Based on measurements in plastics samples, tonnages of halogenated FRs in recycled plastics in China were estimated. Total levels of twelve halogenated flame retardants (HFRs)* were measured in 23 samples of recycled plastics, manufactured in five Chinese provinces. Mean total HFR concentrations were approx. 4 – 60 µg/kg for different recycled polymers tested**.
READ MOREPIN compounds to recycle polyurethanes
Phosphorus, nitrogen and inorganics used in polyurethane chemical recycling produce PIN flame retardant recycled PUR. Glycolysis is the most widespread route for chemical recycling of polyurethanes (PUR). Glycols or glycerol (which can be bio-derived), with catalysts, are used as depolymerising agents (usually at around 180 to 240°C).

Texas A&M scientists propose phosphorus-based one-dip UV cured fire protective coatings for wood and other materials. The new coating presented at the ACS (American Chemical Society) conference uses an aqueous solution of hydroxyethyl methacrylate phosphate (HMP) monomer, polyethylenimine (PEI) polymer and a the photoinitiator TPO.

Iron alginate at 8% w/w in epoxy resin halved both peak heat release rate and smoke release rate in epoxy. Iron alginate was produced by aqueous reaction of sodium alginate, which can be extracted from marine plants, with the ferric salts, then dried, pulverised and mixed into epoxy resin during curing.
