PIN synergists to improve PIN FR performance
De-Yi Wang, IMDEA Materials Institute, Madrid, Spain presented research into new functionalized nano-materials as PIN flame retardants (layered double hydroxides, nano-clays, nano-carbons, nano silicates, etc.) as well as composites combining e.g. minerals (such as iron or aluminium) into nano-materials, or use of nano-materials as interfacial catalysts for ammonium polyphosphate (nano silicates on the surface of APP).
These combinations showed better fire performance in epoxies, EVA, PS, PLA etc. than non-functionalised nano-materials or flame retardants without nano synergists. In addition, a new flame retardant mechanism has been proposed.
