Influences of turkey feather fiber loading on significant characteristics of rigid polyurethane foam: Thermal degradation, heat insulation, acoustic performance, air permeability and cellular structure

This comprehensive study delves into the preparation and detailed characterization of rigid polyurethane foams (RPUFs) filled with varying content levels (3, 6, 9, 12 and 15 wt%) of turkey feather fibers (TFFs) fabricated from the waste feathers. TFFs-loaded RPUFs were successfully produced via one-shut free-rise method in a closed mold. The obtained foam samples were evaluated by the examination of their chemical structure (FTIR analysis),...
