Michael Grosshauser, Fraunhofer LBF, summarised tests of ageing of cable compounds (polyethylene, EVA) with nano-clays. Nano-clays cause premature degradation of these polymers with weathering, because of carbonyl formation, accentuated when used with ATH (aluminium...
Thanos Porfyris, National Technical University, Athens, presented work underway in the EU-funded EPAnEK project testing non-halogenated flame retardants for polypropylene electrical cable conduits and tubes. These are not today covered by the EU Construction Products...
Serge Bourbigot, Centrale Lille / UMET France, indicated an increase in the number of publications addressing intumescents for fire safety of around 4x from 2000 to 2020*. He summarised tests using different amounts of expandable graphite (EG) and conventional...
Ivan Kotek, Funzionano, presented the company’s silicon-containing POSS (polyhedral oligomeric silsesquioxane) PIN FRs, see presentation at the previous AMI FRiP conference in pinfa Newsletter n°124. These highly-branched organo-mineral nano-polymers are free of any...
Yann Bourgeois, Huber Martinswerk, presented results of combining zinc melamine polyphosphate (ZMP intumescent) and aluminium tri hydroxide (ATH) for LSZH (low smoke zero halogen) cables (polyethylene – EVA). The zinc in ZMP is known to reduce smoke emission and the...
