Study of fire retardancy, thermal and mechanical properties of HDPE-wood composites

This article reports a study of flame retardancy, thermal and mechanical properties of wood plastic composites (WPCs) based on high density polyethylene and pine flour. Study shows that sample composition plays an important role in WPC’s properties. Influence of additives like fillers (SiO2 or CaCO3) and flame retardants ammonium polyphosphate (APP) and pentaerythritol (PER) on WPC’s properties has been considered. The best properties are showed in samples using SiO2 as filler and treated with intumescent fire retardant APP/PER. Such samples have excellent fire retardancy with V-0 rating (UL-94 test) and imply that APP/PER fire retardant ensures effective fire retardancy for WPCs.
