Report underlines importance of fire statistics to define policies to reduce fire risks and proposes standards for data. The Firestat project was requested by the European Parliament and engaged by the Commission. Information on fire statistics was collected from the...
A review of flame retardants for rigid and flexible polyurethane (PU) foams shows that progress is centred on PIN solutions. The authors underline the high fire risks of PU foams, the consequent need for flame retardants to inhibit ignition and reduce flammability,...
Aerospace specialist Xeriant has developed a low-toxicity, low-smoke PIN FR for textiles, constructions and polymers. The non-halogen, bulk additive can be used in compounding, applied to textiles or used with cellulosic materials. Applications to date include...
Compounding World’s annual review of flame retardants notes high interest and development of all types of PIN FR systems. New grades of phosphonates and other PIN chemistries, with specific PIN synergists, aim to achieve both UL 94 V-0 for thin wall sections and...
Researchers tested a sulphur polyphosphonate PIN flame retardant in PET achieving UL 94 V-0 (3.2 mm) at 8% loading but with dripping. The polysulfonyldiphenylene phenylphosphonate (PSPPP, a polyphosphonate) was synthesised by reacting phenylphosphonic dichloride with...
