Durable PIN FR for nylon/cotton fabrics

Water-soluble cyclophosphazenes provide effective, wash-resistant fire resistance to 50:50 “nyco” blend fabric. The novel phosphorus-nitrogen PIN compound, hexa (allylamine) cyclotriphosphazene (CPZ), see Mayer-Gall et al. in pinfa Newsletter n°106, was reacted with...
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...
