Eco-Friendly Approach and Potential Biodegradable Polymer Matrix for WPC Composite Materials in Outdoor Application

Table 4

TGA results for HDPE-PLA blends with different compatibilizer percentages and HDPE50-PLA50 matrix composites with 3 wt.% of compatibilizer and 20, 30, and 40 wt.% of wood flour. (°C) is evaluated with the extrapolated onset temperature from TGA curve. (°C) is the temperature of maximum DTG curve peaks. (%) is the mass variation percentage between the total amount of sample before the test and the residual mass after the test.
