The tensile strength of acrylic can reach the level of 50-77MPa, and the bending strength can reach the level of 90-130MPa. The upper limit of these performance data has reached or even exceeded some engineering plastics. Its elongation at break is only 2%-3%, so the mechanical properties are basically hard and brittle plastics, and have notch sensitivity, easy to crack under stress, but the fracture is not like polystyrene and ordinary inorganic glass That's sharp and jagged. 40°C is a secondary transition temperature, which is equivalent to the temperature at which the pendant methyl group starts to move. Above 40°C, the toughness and ductility of the material will be improved. Polymethyl methacrylate has low surface hardness and is easy to scratch.
The strength of acrylic is related to the time of stress action. As the action time increases, the strength decreases. The mechanical properties of the polymethyl methacrylate (oriented plexiglass) after stretching and orientation are obviously improved, and the notch sensitivity is also improved.
