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). This product was then tested at 1 – 3 %...
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). The magnesium containing coating achieved flame...
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. The nano-porous structure of the aerogel resulted in improved thermal...
FRPM 2019, the 17th conference on Flame Retardant Polymeric Materials, brought together in Turku, 26-28 June 2019, some 220 participants worldwide. The conference showcased a wide range of R&D into novel non-halogenated flame retardant chemicals, as well as other...
Steve Hollins, ECHA (European Chemical Agency), suggested that industry should be proactive in substituting chemicals which are flagged as possibly problematic on any of the different ECHA ‘early warning’ lists, such as PACT (public activities coordination tool),...
