Amine-reacted APP PIN FR

Amine-reacted APP PIN FR

A Schiff base (an amine nitrogen compound) was reacted with ammonium polyphosphate (APP) achieving UL 94 V-0 (3 mm) at 17% loading in unsaturated polyester. 1,2-bis(2-aminoethoxy)ethane and terephthalaldehyde (TPA) were reacted with APP in ethyl acetate at 65°C to...
Bio-based PIN FR for PET fabric

Bio-based PIN FR for PET fabric

Phytic acid and chitosan layer-by-layer coating of PET fabric shows semi-durable, non-drip fire performance. Woven 120 g/m2 PET (polyethylene terephthalate) was prepared by heating to 60°C in sodium hydroxide, then alternate layers of phytic acid and chitosan were...

pinfa’s Q&A (8 pages) provides detailed information for users on regulatory impacts of the EU’s CSS on PIN flame retardants, including REACH, CPL, Assessment of Regulatory Needs and the ECHA Flame Retardant Strategy, “Grouping” of FRs, Regrettable Substitution,...
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...
