Know we have talked about the benefits of Halloysite nanotubes as a flame retardant but this new study would be a very interesting read if I could see the whole artical.

Influence of halloysite nanotubes onto the fire properties of polymer based composites:

Highlights
•Halloysite nanotubes offer a good alternative as carriers of flame retardant systems

•Halloysite nanotubes improve the fire properties of polymer-based formulations

•Fire retardancy properties depend on both the HNT content and the polymer nature.

Abstract.
Fire retardancy is of crucial importance for most of the polymer applications and fire proofing materials are often based on polymer blends with high fire retardants contents (up to 60wt%) which induce cost increase and lower mechanical performances. The use of ammonium polyphosphate (APP) as fire retardant allows maintaining good mechanical properties but it can be removed from the polymer matrix under hygrothermal conditions. In this context, halloysite nanotubes (HNTs) offer a good alternative as carriers of flame retardant systems to control the migration of the flame retardant molecules encapsulated in the HNT lumen for long-term aging properties. This review highlights the influence of the presence of HNTs and its derivatives on the fire retardancy performances of polymer-based composites. The discussion is examined according to the nature of the polymer from thermoplastics to thermosets.
