Innovative PIN FR application: polyelectrolytes

Innovative PIN FR application: polyelectrolytes

Jaime Grunlan, Texas A&M University, USA, presented polyelectrolytes as a mode of PIN flame retardant surface application to materials such as textiles or polymers. Two different chemicals are dissolved in water. A pH change causes the two to react together and to...
PIN flame retardants for wood and fibres

PIN flame retardants for wood and fibres

Adèle Lamandé, CSTB France (national construction technical centre), presented studies of gas emissions from timber laminates under different oxygen concentrations, intended to simulate different fire conditions. She underlined that three quarters of deaths in...
Bio-based PIN flame retardants

Bio-based PIN flame retardants

Maxinne Denis, University of Montpellier, France, presented testing of bio-based PIN flame retardants for alkyd resin coatings. Alkyd resins are widely used in solvent-based paints and coatings, but are flammable (including after application) and leave solvent...
PIN FRs for bio-based insulation materials

PIN FRs for bio-based insulation materials

Lily Deborde, LGCGM Rennes University France, summarised work on PIN flame retardant alternatives to boric acid and ammonium salts for hemp fibre thermal insulation products (blown insulation, panels). The objective is to use local bio-resources in materials to reduce...
Weathering of PIN flame retardant materials

Weathering of PIN flame retardant materials

Sandrine Therias, Institut de Chimie de Clermont Ferrand France, reviewed literature on weathering of PIN flame retarded polymers. In some cases, changes in fire performance after weathering result from deterioration of the polymer, not of the flame retardant. Certain...
