Acrylic board has the general transparency of crystal, the light transmittance is over 92%, and the acrylic board colored with dyes has a good color development effect. In addition, acrylic board has excellent weather resistance, high surface hardness and gloss, and good high temperature resistance. Acrylic board has good processability, and can be divided into casting type and extrusion type according to production technology. It can be thermoformed (including die pressing, blow molding and vacuum blister) or machined by drilling, turning, milling and cutting. The mechanical cutting and carving controlled by microcomputer not only greatly improves the machining accuracy, but also can produce more exquisite patterns and shapes than traditional methods. In addition, acrylic boards can be cut by laser and carved by laser to make products with peculiar effects.
Hardness is one of the parameters that can best reflect the production process and technology of cast acrylic board, and it is an important link in quality control. Hardness can reflect the purity of raw material MMA, weather resistance and high temperature resistance of the board, etc. Hardness directly affects whether the board will shrink and bend, and whether the surface will be cracked during processing. Hardness is one of that hard index to judge the quality of acrylic board. The cast acrylic plate has the highest hardness index at present, with an average Dallow hardness of 90 degrees.
Acrylic board has excellent weather resistance, especially used outdoors, ranking the highest among other plastics, and has good surface hardness and luster, and high processing plasticity, which can be made into various required shapes and products. There are many kinds of plates with rich colors (including translucent color plates), and another feature is that thick plates can still maintain high transparency.
