Thermal and Mechanical Properties of Materials with Adverse Effect on the Environment


Cite

In this study, we evaluate the thermal and mechanical properties of materials based on polypropylene (PP), high-density polyethylene (HDPE), and polyethylene terephthalate (PET) using the thermogravimetric analysis and impulse excitation technique. The results show that even if the melted input material together with the pressure of ~4 MPa was used to produce the samples, we can find small cavities around the sand grains in the samples. In case of thermal stability, the results show that in case of HDPE + PET combination, higher temperature should be used. Besides that, the results show that sand should increase the Young’s modulus of the samples from recycled materials.
