Thermal Conduction of Elastomeric Polyurethanes with Titanium Dioxide as Mineral Filler and its Composites with Recycled Kevlar Fabric

Thermal Conduction of Elastomeric Polyurethanes with Titanium Dioxide as Mineral Filler and its... Thermal conduction of composites made from Kevlar® fabric and polyurethane (PU) mineral-filled elastomers was studied. Contact heat conduction was measured according to ISO 12127 standard (which measures the threshold time required for a 10°C increase throughout the sample). PU elastomer filled with TiO2 did not show significant differences in the threshold time for heat conduction as compared to neat PU elastomer although the values tended to be lower. The maximal threshold time was obtained for PU elastomer with TiO2 (125 s for a sample 8 mm wide). No significant differences in the threshold time were observed for other PU elastomers with either TiO2 filler or two added organic fire retardants. Composites made of both Kevlar® fabric/PU and Kevlar®/PU/Kevlar® complied with ISO 15538:2001 standard for firefighter clothing. The aim was to determine if recycled Kevlar® fabric could replace Nomex®, poly(m-phenylene isophthalamide), a costly material of choice in the textile industry for firefighter structural suits. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Fibre Chemistry Springer Journals

Abstract

Thermal conduction of composites made from Kevlar® fabric and polyurethane (PU) mineral-filled elastomers was studied. Contact heat conduction was measured according to ISO 12127 standard (which measures the threshold time required for a 10°C increase throughout the sample). PU elastomer filled with TiO2 did not show significant differences in the threshold time for heat conduction as compared to neat PU elastomer although the values tended to be lower. The maximal threshold time was obtained for PU elastomer with TiO2 (125 s for a sample 8 mm wide). No significant differences in the threshold time were observed for other PU elastomers with either TiO2 filler or two added organic fire retardants. Composites made of both Kevlar® fabric/PU and Kevlar®/PU/Kevlar® complied with ISO 15538:2001 standard for firefighter clothing. The aim was to determine if recycled Kevlar® fabric could replace Nomex®, poly(m-phenylene isophthalamide), a costly material of choice in the textile industry for firefighter structural suits.
