Titel
Development of flame-retarded wood-plastic composites (WPC)
Abstract
Fire retardancy of wood-polymer composites (WPC) needs to be improved new applilations for these materials. Usually, fire retardants (FR) are added during the compounding step to increase fire retardancy of WPC. In this research project, a wood pre-treatment was carried out to further improve the fire performance of WPC for application as sidings (facades). Based on results obtained for the limiting oxygen index as well as UL94-tests, the single burning item (SBI) test according to EN 13823 was performed. When pre-treated wood particles were used, classification C-s3, d0 was achieved for WPC sidings with a HDPE matrix while D-s2, d0 was achieved with untreated wood particles, based on single SBI tests performed for each formulation. This indicates a benefit of the wood particle pre-treatment to improve fire performance of WPC.
