Acrylic has good comprehensive mechanical properties and is in the forefront of general-purpose plastics. The tensile strength, tensile strength, compression and other strengths are higher than that of polyolefins, and higher than that of polystyrene and polyvinyl chloride. The impact toughness is poor, but it is slightly better. Polystyrene. The cast bulk polymethyl methacrylate sheet (such as aerospace plexiglass sheet) has higher mechanical properties such as stretching, bending and compression, and can reach the level of engineering plastics such as polyamide and polycarbonate.
In general, acrylic tensile strength can reach 50-77MPa level, bending strength can reach 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 it has the sensitivity of notch. It is easy to crack under stress, but the fracture is not like polystyrene and ordinary inorganic glass. It’s sharp and uneven. 40 ° C is a secondary transition temperature, which is equivalent to the temperature at which the side methyl group starts to move. When the temperature exceeds 40 ° C, the toughness and ductility of the material are improved. Polymethyl methacrylate has a low surface hardness and is easily scratched.

The light transmittance is over 92%, and the acrylic board colored with dye has a good color development effect. In addition, the acrylic sheet has excellent weather resistance, high surface hardness and surface gloss, and good high temperature resistance. . Acrylic sheets have good processing properties and can be divided into casting type and extrusion type according to the production process. Both thermoforming (including molding, blow molding, and vacuum blistering) can be used, as well as mechanical processing such as drilling, turning, washing, cutting, and the like. Micro-computer controlled mechanical cutting and engraving not only greatly improve the processing accuracy, but also create more beautiful patterns and shapes than the traditional way. In addition, the acrylic sheet can be laser-cut and laser-engraved to produce strange products.

Hardness is one of the parameters that can reflect the production process and technology of pouring acrylic sheet, and is an important part of quality control. The hardness can reflect the purity of the raw material MMA, the weather resistance of the sheet, and the high temperature resistance. The hardness directly affects whether the sheet will shrink and bend, and whether the surface will be cracked during processing. Hardness is one of the hard and good indicators for judging the quality of acrylic sheets. The cast acrylic sheet has a current high hardness index with an average Dyro hardness value of 90 degrees.
