1 000 London buildings are fire-unsafe

London Fire Brigade says 1 149 buildings in London need a 24-hour “waking watch” because of severe fire safety defects. These “waking watches” were put into place in fire-unsafe buildings in London following the Grenfell Tower fire, in which 72 people died.

PIN FR performance PPA for EVs and E&E

Solvay’s partially bio-based long-chain PPA achieves UL94 V-0 (at 0.4 mm) with processability, strength and stability. The non-halogenated flame retardant polyphthalamide formulations offer processing advantages of high glass transition temperature and melting point (Tg 135°C, Tm 315°C) adapted to non-blistering reflow soldered surface mount devices (SMD) and parts in cooling systems for power electronics or fluid connectors, and to production of miniaturised components

Inovia Materials ionic liquid PIN FRs

Ionic liquids as PIN FRs for a range of polymers, offering fire resistance and low impact on performance and processing. The ionic liquids, based on salts in which one ion has delocalised charge and one component is organic and biodegradable, contain phosphorus, nitrogen and sulphur, and afford structure design flexibility enabling performance in different polymers.

Reactive PIN FR for polyurethane foam

A reactive phosphorus – nitrogen PIN FR improved both fire performance and mechanical properties in flexible PUR foam. A complex dihydroxy P – N molecule 2- (( bis (2-hydroxyethyl) amino) methyl) -5,5-dimethyl -1,3,2-dioxaphosphinane 2-oxide (HAMPP) was synthetised in three reaction stages and tested in flexible polyurethane foam at 0 – 10% loading.

Polyphosphoramide PIN FR for PLA

A polymeric phosphorus – nitrogen PIN FR was synthesised without using solvent achieving UL 94 V-0 in PLA at 2% loading. The polyphosphoramide DM-H was synthesised in a two-step, one-pot controlled condensation reaction, without solvents or catalysts, using HAD (1,6-hexanediamine) and DMMP (dimethyl methyl-phosphonate), resulting in an oligomer MW = 6 800 g/mol containing c. 7 -11 wt% N and 12 – 16 wt% P

Comparing PIN and halogenated FRs in PP

A novel PIN FR achieved fire and mechanical performance comparable to a brominated/antimony FR package. In polypropylene, a novel mono-constituent, intumescent PIN FR (PNP1D, combining phosphate ester, polyhydroxyl and melamine) was compared to DecaBDE or DecaBDE+HBCD (Br-FRs) with ATO (antimony trioxide).
