Production of Typha domingensis thermal insulation boards for refrigeration

The present study proposes formulations of ecomaterial insulation based on Typha domingensis for the design of insulation boards for refrigerators. The biosourced chips are obtained by thermopressing a Typha + cassava starch composite, with Typha particles (particle size ) and starch. The values obtained for the samples with binder show a thermal conductivity varying between and . After demoulding and drying, briquettes measuring or are obtained, with thicknesses of between and 5 . A case study shows that, in addition to their environmental benefits, these briquettes significantly reduce thermal loads compared with polyurethane, attesting to their excellent insulating properties.
