An account is given herein of research results for composites of elastic polyurethane (EPUR) combined with milled poultry feathers. We present the properties of keratin fibres obtained from feathers and the change in those properties which the feathers induce in the EPUR foam. The structure of the composites was determined by spectrophotometric- (FTIR), thermal- (DSC) and thermogravimetric (TGA) analyses as well as by scanning electron microscopy (SEM). Assessed were also the burning-and acoustic properties, and thermal conductivity. The addition of ground feathers to EPUR increases its limiting oxygen index and reduces the effect of “falling drop”. Another benefit is a distinct increase in the temperature of the maximum degradation rate of the foam hard phase.

Elastyczne pianki poliuretanowe (EPUR) modyfikowano włóknami keratynowymi z piór kurzych. W artykule przedstawiono właściwości keratyny uzyskanej ze zmielonych piór kurzych i zmiany w strukturze oraz właściwościach pianek EPUR spowodowanych wprowadzeniem napełniacza w postaci włókien keratynowych. Do oceny budowy chemicznej wykorzystano analizę spektrofotometryczną FTIR, termiczną DSC i termograwimetryczną TGA oraz skaningową mikroskopię elektronową SEM. Oceniono właściwości palne, akustyczne oraz przewodność cieplną otrzymanych kompozytów EPUR, potwierdzając przydatność modyfikatora do produkcji EPUR.
