READ MORERoom tests show UK furniture regulations effective
Nine full-scale furnished room fire tests were carried out with furniture corresponding to current UK, French and US fire safety requirements. The UK Furniture Fire Safety Regulation require both smoulder and open flame fire resistance whereas France (EN 1021-1) and the US (current California TB117-2013) require smouldering cigarette resistance only.
READ MOREMedia recognise value of FRs in protecting cars
Fox2, USA, has published a story warning the public that a water bottle left in a car in the sun can be a fire risk. The article quotes however the Getty Conservation Institute: “seats are designed to be fire-retardant and self-extinguishing, thus your car seat is more likely just have a burned hole in it than to actually catch fire.
READ MOREFires starting in furniture cause 14% of fire deaths
A study of fire statistics in Massachusetts 2003-2016 shows that fires involving furniture caused 14% of all residential fire deaths. Data was assessed from 158 862 residential fires reported as causing human or monetary damage. Fires with no information on fire cause and intentional fires were excluded, leaving 34 081 fires analysed.
READ MOREDimelamine pyrophosphate PIN FR for epoxies
Dimelamine pyrophosphate (DMPY) was synthesised in one step (97% yield) from melamine and sodium pyrophosphate, then tested as a flame retardant in DGEBA/PDA epoxy resin at 0 – 12% loading. UL94-V1 (3.2 mm) was achieved at 8% DMPY and V0 at >9%. LOI was increased by up to 50% (at 12% loading).

A zinc oxide – organic triazine compound (OTCA-ZnO) was prepared and tested as a flame retardant in EVA (ethylene-vinyl acetate polymer) in combination with APP (ammonium polyphosphate) at total loading of 25% (App 0-25%, OTCA-ZnO 25-0%) by melt-mixing.
READ MOREPhosphate mine waste effective as FR
“Phosphorus tailings” - waste generated in large quantities by phosphate rock mining (in this study, from Tiaoshuihe phosphate mine, Hubei Sanning Mining, China) were tested as a flame retardant, at 2.5 – 10% loading, with 15 – 25% aluminium hypophosphite, in TPU (thermoplastic polyurethane).
READ MORESulfenamide synergists for PIN FRs
Sulfenamides are organic PIN chemicals containing nitrogen-sulphur bonds and carbon rings. Five different sulfenamides were synthesised, with in some cases additional nitrogen groups, and were tested as synergists to PIN flame retardants in polypropylene (phosphonate ester, aluminium hypophosphite, AHP, ATH, APP).
