New applications for PIN flame retardants

New applications for PIN flame retardants

Sabyasachi Gaan, EMPA Switzerland, presented testing of PIN FRs in reactive extrusion of polyamide. An oligomeric phosphorus PIN flame retardant was embedded in polyamide, by reaction of a phosphorylated vinyl monomer (DVPPO) with the cyclic amine (piperazine) in...

Environment and safety

Jérémie Pourchez, Mines Alès France, presented analysis of nano-particles in fly ash (from offgas filters) and bottom ash, both from laboratory incineration of ethylene vinyl acetate polymer containing nano-minerals: silica, alumina, boehmite, zinc, titanium. These...
Innovative flame retardant coatings

Innovative flame retardant coatings

Maude Jimenez, UMET Lille University, France, presented investigations of self-stratifying epoxy/silicone coatings, with the aim of achieving railway fire safety requirements. The principle of self-stratification is to create a multi-layered coating in a one-pot...
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...
