Development of a thermogravimetric analysis (TGA) method for quantitative analysis of wood flour and polypropylene in wood plastic composites (WPC)

▸ We developed a special thermogravimetric analysis (TGA) method to quantify the mass percentage of wood flour and polypropylene copolymer in wood plastic composites (WPC). ▸ We fitted the heating rate to the thermal degradation of the single components by using dynamic and isothermal segments. ▸ We showed that WPC with known composition can be rapidly quantified with TGA measurements, therefore, TGA is a useful tool for WPC production control.
