Ivan Kotek, Funzionano, presented the company’s range of silicon-containing POSS (polyhedral oligomeric silsesquioxane) PIN FRs, developed with Norwegian research centre SINTEF. These are highly-branched nano-polymers in which the organic group can be modified to design specific compounds adapted to different polymer matrices and for different customer applications. These organo-mineral FRs are free of any hazard labelling and can replace halogenated FRs and ATO (antimony tri oxide), in synergy with other PIN FRs, particularly in polyethylene, polypropylene, polyurethane, rubbers. Examples of applications shown, with fire test results, included in polyurethane (peak heat release halved with POSS, pass for EN-ISO 11925-2 30s flame), in glass fibre unsaturated polyester, with ATH and peroxide, again passing EN-ISO 11925-2, in vinyls and epoxies, offering self-extinguishment and reduced flame spread.
