Description
| - Polyurethane (PUR) based open cell foams (Gumotex, Breclav, Czech Republic) and PUR based nonwoven nano-fabric (SPUR, Zlin, Czech Republic) produced by means of Nanospider technology (ELMARCO, Liberec, Czech Republic) thermal stabilities (DTA, TG analysis) in the temperature range of + 40 to + 500 °C were studied with respect to their application in automotive and aeronautic industry as sound damping materials. Correlation between PUR chemical structure, dimensions of the foam individual cells, nano-fabric air flow resistivity, mechanical, acoustic prop-erties and thermal stability were evaluated. For thermal degradation data evaluation the formal ki-netic model proposed by Ozawa, Flynn and Wall was applied (ʺT. Ozawa: Bull. Chem. Soc. Japan, 1965, 38, 1881ʺ). It was found, that the thermal degradation consists of two steps: 1.step in the temperature range 200 ? 310 °C, weight loss of 23 ? 58 % (activation energy 97 kJ/mol), 2. step in the temperature range 310 ? 450 °C, weight loss 33 ? 71
