Endothermically decomposing mineral fillers, such as aluminium or magnesium hydroxide, magnesium carbonate, or mixed magnesium/calcium carbonates and hydroxides, such as naturally occurring mixtures of huntite and hydromagnesite are in heavy demand as sustainable, environmentally benign fire retardants. They are more difficult to deploy than the halogenated flame retardants they are replacing, as their modes of action are more complex, and are not equally effective in different polymers. In…

Effect of metal chelates on the ignition and early flaming behaviour of intumescent fire-retarded polyethylene systems
Abstract Polyethylene (PE) was treated with various formulations containing an intumescent fire retardant, which consists of melamine phosphate (MP), pentaerythritol (PER) and ammonium polyphosphate
Fire retardancy of a reactively extruded intumescent flame retardant polyethylene system enhanced by metal chelates
Abstract A reactive extrusion technology was adopted to synthesize a flame retardant (ER), based on the esterification of melamine phosphate and pentaerythritol. The ER imparts good flame retardancy
Basic magnesium carbonate flame retardants for polypropylene
Magnesium hydroxide and magnesium carbonates have attracted attention as endothermic flame retardants that are sufficiently stable to be incorporated into thermoplastics without decomposition. In
Fire retardant effects of polymer nanocomposites.
TLDR
The influence of polymer nanocomposite formation on the yields of toxic products from fire is studied using the ISO 19700 steady state tube furnace, and it is found that under early stages of burning more carbon monoxide and organoirritants are formed, but under the more toxic under-ventilated conditions, less toxic products are formed.
The fire retardant behaviour of huntite and hydromagnesite – A review
Naturally occurring mixtures of hydromagnesite and huntite have found important industrial use. Their endothermic decomposition over a temperature range similar to that of commonly used polymers and
A study of the mechanism of flame retardance and smoke suppression in polymers filled with magnesium hydroxide
Abstract At sufficiently high loadings, magnesium hydroxide is shown to be an effective flame retardant and smoke suppressing additive for selected thermoplastics. However, for polypropylene
Combustion toxicity of fire retarded EVA
Abstract A Purser furnace has been used to investigate the combustion toxicity of ethylene-vinyl acetate copolymer (EVA) with and without fire retardants, under different fire conditions. Steady
Nanomorphology and reaction to fire of polyurethane and polyamide nanocomposites containing flame retardants
Abstract The reaction to fire of polymer nanocomposites (thermoplastic polyurethane and polyamide-6) containing two different nanofillers (organoclay and carbon nanotube) has been investigated.
Flame retardant effects of magnesium hydroxide
Abstract Magnesium hydroxide has all the characteristics required for use as a flame retardant filler. It can be made synthetically with high purity and in a range of useful morphologies, responds
Flammability assessment of tannin-based cellular materials
Fire retardance of highly porous tannin-based rigid foams formerly suggested as new, ecological, insulation materials, has been investigated in detail. For that purpose, one standard composition was
