Polymeric P FR selected for airport seating

FRX polyphosphonate PIN flame retardant has been selected to ensure fire safety of airport polyester seat fabrics. The polyphosphonate is combined with polyester to produce a fabric blend achieving airport fire safety requirements. FRX and Sichuan EM Technology are...
Polymer smoke toxicities

Polymer smoke toxicities

Seven construction polymers were tested for fire performance and smoke, showing considerably different toxic emissions. Cone calorimeter, thermogravimetric analysis and FTIR (Fourrier Transform Infrared Spectroscopy) were used to analyse fire performance (flashover...
Polymer smoke toxicities

Fire and smoke toxicity for sandwich panels

Flame retarded phenolic foam core panel showed lowest toxic smoke emissions, did not reach danger limit for warehouse fire. Recent major fires have occurred in warehouses and logistics centres in South Korea (e.g. Icheon 38 deaths, Yongin 5 deaths, both 2020) and...
Causes of fires in photovoltaics

Causes of fires in photovoltaics

Fires in PV are estimated to occur at c. 3 fires per year per 100 MW capacity installed, with connectors a significant cause. Other fire causes are the PV module itself, DC isolator switches and fuses, cables and inverters. Because PVs generate continuous current,...
APP oyster shell bio-based flame retardant

APP oyster shell bio-based flame retardant

Oyster shell powder reacted with ammonium polyphosphate reduced heat and smoke release of epoxy resin 70 – 80 %. Oyster shell powder (300 mesh) was ball milled with NaClO (0.3% w/w to oyster shell) for several hours, then added to APP (ammonium polyphosphate 2500...
