| Popis: | In this study, the main processing and formulation factors that affect the performance of panels manufactured with post-consumer TetraPak® and high-density polyethylene compounds were analyzed. The water uptake of the materials during immersion was also studied to identify the limitations on the application of this compound. Before obtaining the boards, the raw material was ground until flakes, and then blended varying the amount of high-density polyethylene added to the TetraPak® from 5 to 20 wt%. The boards were obtained by thermo-compression and tested according to ASTM standards. The results show that mechanical strength depends more on the pressing time than formulation. On the other hand, the specimens tested by immersion in water for 17 days exhibited water absorption of 60 wt% about its dry weight. Even with this amount of humidity, its structural stability was not compromised. |
