Poly- and cyclo- phosphazenes are recognised effective PIN flame retardants, but to date are not available as water soluble and permanent systems for textiles.
READ MORESystemic analysis of P-N flame retardant design
Four comparable phosphorus-containing compounds were synthesised, each with one central P atom and three hexenyl groups: an amide (P bonded to 3xN), a diamidate (P bonded to 2xN, 1xO), an amidate (P bonded to 1xN, 2xO) and a phosphate (P bonded to 3xO).
READ MOREFerrocene polymer synergist for APP
A polymer (poly((3,3’-diphenyl diacetylethylenediamino)-1,1’-ferrocene) = PDPFDE) was synthesised linking ferrocene, aromatic carbon rings and the nitrogen compound ethylenediamine.
READ MOREMelamine – bio-sourced phytate FR for polypropylene
Melamine and phytic acid (a molecule naturally found in plants) were reacted in aqueous solutions. The six phosphates in phytic acid reacted with six melamines, and two-dimensional nanoflakes were formed in drying (MEL-PA).
READ MOREP-ester / magnesium synergy for wood FR
Cyclic phosphate ester was reacted with magnesium hydroxide (1 – 6 %) and then tested with melamine formaldehyde and pentaerythritol (at ratios 1:1 to 1:4) as a flame retardant coating on 4 mm plywood (250 g/m2 coating).
READ MORESilica aerogel as FR and smoke suppressant
Polyurethane insulation foam (PUF) was surface treated with silica (SiO2), by acid and alkali hydrolysis, then lyophilised to generate a silica aerogel at 13 – 33% w/w loading on the foam.

Sabyasachi Gaan, EMPA Switzerland, presented development of DOPO derivative phosphorus PIN FRs for use in synthetic and bio-based polymers, from research through to industrial production: DOPO phosphphonamides (EDA-DOPO = 6,6'-(Ethane-1,2-diylbis(azanediyl))bis(dibenzo[c,e][1,2]oxaphosphinine-6-oxide)), today REACH registered and entering commercialisation by Metadynea; DOPO-PEPA (PEPA = 1-oxo-4-hydroxymethyl-2,6,7-trioxa-l-phosphabicyclo[2.2.2] octane), REACH registration underway, for application in polyester and polyolefins, under development with JET-Aviation for non-halogenated fire safety of wood products for aviation applications; and triazine DOPO, under development with BRUAG.
READ MOREResearch into bio-based PIN flame retardants
Xin Wang, University of Science and Technology of China, presented proposed PIN FRs derived from bio-based cardanol, tested in epoxies, including by reaction with organic phosphorus chemicals such as phosphaphenanthrene or benzoxazine, with zirconium phosphate, in combination with boron graphene nanosheets and in layered double hydroxides.
READ MOREResearching new FR coating technologies
Bartosz Weclawski, University of Bolton, UK, presented research into use of plasma technology based on an atmospheric pressure plasma and high power UV laser. Multiplexed Laser Surface Enhancement (MLSE from MTIX Ltd., UK) can bond fire retardant precursors physico-chemically and even covalently into a fabric, followed by plasma/UV, so avoiding the conventional wet processing cycles.
READ MOREFire safety for wood and timber
In the wood and timber sectors, Teknos’ industrial customers today are looking for ‘green’ coating and treatment solutions: water based, VOC emissions free, non-halogenated and if possible bio-based. In the construction sector, demand for fire safety treatments is increasing, especially for public buildings, with today also demand for low smoke (Euroclass).
