Evaluation of Temperature Influence on Tensile Strength and Izod Impact Resistance on Poly Methyl Methacrylate (PMMA)

Abstract:

The increasing use of poly methyl methacrylate (PMMA), often replacing tempered glass, is a consequence of its high rigidity, practicality, lightness and transparency. However, current manufacturing standards in the polymer industry recommend specific tests on these materials. The present study aims to mechanically test the properties of poly methyl methacrylate (PMMA) material under conditions that simulate a much more aggressive environment than usual. Infrared spectroscopy (FTIR), thermogravimetric (TG/DTG) tests, Izod impact tests, and scanning electron microscopy (SEM) analysis were performed. The results showed that poly (methyl methacrylate) (PMMA) maintained its tensile mechanical properties up to 105°C. Regarding the impact tenacity, the temperature negatively influenced the performance of this polymer.
