Rapid mass calorimeter - High throughput fire performance screening

  • Modern flame retardant polymeric materials often stand for multicomponent systems consisting of different ingredients. Using a variety of flame retardants, fillers, additives, synergists and adjuvants as well as applying different concentrations, particle size distributions, encapsulation, and so forth lead to a vast multidimensional matrix of possible formulations. Actual, comprehensive elucidations are no longer possible due to time, material and cost limitations. The task is dying for accelerated procedures, for high-throughput methods. Therefore we developed the Rapid Mass Calorimeter based on a Mass Loss Calorimeter with attached thermopile chimney and a linear motion unit for semi-automatic sample change. Together with the reduction in specimen size (2 cm x 2 cm), a saving of time around 70% and a saving of material of 96% is achieved not considering the strongly reduced calibration and maintenance efforts required for the Mass Loss Calorimeter.

The correlations between the results of the Rapid Mass Calorimeter and the Cone Calorimeter as well as to the Oxygen Index and UL94 classification are described; the effects such as when reducing the specimen size are discussed.zeige mehrzeige weniger
