Abstract

The subject of the research presented in this article is viscoelastic polyurethane foams (VPF) made using a halogen free flame retardant additive – Fyrol™ – and keratin fibers. The foams were made with varying isocyanate index. For their modification, Fyrol PNX LE and Fyrol PNX were used as well as keratin fibers obtained from poultry feathers. Foams were characterized by means of techniques such as infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. The changes in the patterns of the foams were analyzed using a scanning electron microscope. Moreover, flammability of selected foams was defined using a cone calorimeter and oxygen index. Compression set of the foams was assessed. As a result, it was concluded that the use of a Fyrol mixture with keratinous fibers preferably reduces permanent deformation of foams and a fire hazard caused by their usage.
