title: POLYURETHANE FLAME RETARDANT FORMULATION
number: WO2012116885
publication date: 7 september 2012 (PCT)
applicant/assignee: Huntsman Polyurethanes
Gist: A PU formulation with a mixture of ammonium polyphosphate and nano metal oxide particles (Mg or Al)
Why it is innovative: While synergistic effects of fire retardant combinations are known and claimed in many patents, the use of very small metal oxide particles together with APP seems to have a real and significant effect.

Hello World!
This is the first entry in my blog on ‘Innovation in Polyurethanes’. Here I will present the -in my opinion- most interesting PU patent applications selected from the recently published patent literature. So not another boring list of patents with meaningless titles and doubtful innovativity, but a short selection of really innovative, remakable or just interesting patent applications, with a few words on the essence (the “gist”) and why they made the list.
I hope it will be useful to you and please let me know what you think.
Best regards
Geert Bleys
