Perspectives on FR polymer recycling

Perspectives on FR polymer recycling

Detailed review of technologies, implementation and perspectives for recycling of flame retardant polymers. Based on over 230 references, of which nearly 30 are summarised in a table, this review covers recycling of different polymers with PIN and with halogenated...
Mechanical recycling of PET with P FRs

Mechanical recycling of PET with P FRs

Recycling of PET fibres with different phosphorus PIN FRs showed that combinations can achieve excellent stability. PET (polyethylene terephthalate) was mechanically recycled with three reprocessing cycles @ 275 – 305 °C (extrude, quench, melt-spin) neat and with two...
PIN FR synergy in recycled ABS

PIN FR synergy in recycled ABS

Combining mineral PIN FRs can improve fire performance and reduce smoke without compromising mechanical performance. Recycled ABS was supplied by the EU CREAToR project which is developing a process to remove brominated flame retardants from and then reuse...
REACH and CLP Classification of melamine

REACH and CLP Classification of melamine

pinfa’s Q&A explains implications for melamine-based flame retardants and for use of melamine itself for fire safety. Melamine has been identified as SVHC under REACH and Carc. 2, H351 and STOT RE 2, H373 under CLP. In melamine-based FRs*, melamine is chemically...
PIN FRs and Recycling

PIN FRs and Recycling

Several presentations and posters at FRPM addressed recycling: Jiuke Chen, Empa, presented tests recycling of PET fibres (two re-extrusion cycles, without ageing) containing phosphorus PIN FRs (DOPO derivate, phosphinate) – see Poster Awards above. Valeria Berner,...
