Technological Properties of Acrylic Plate

Acrylic plate has the transparency of crystal, and the light transmittance is more than 92%. Acrylic plate dyed with dye has a good color development effect. In addition, acrylic plate: has excellent weather resistance, high surface hardness and luster, and good high temperature resistance. Acrylic plate has good processing performance, which can be divided into two types: casting type and extrusion type according to the production process. Both thermoforming (including molding, blow molding and vacuum blistering) and mechanical processing such as drilling, turning, milling and cutting can be used. The mechanical cutting, scraping and carving controlled by microcomputer not only greatly improves the processing accuracy, but also can produce more exquisite patterns and shapes than traditional methods. In addition, acrylic plates can be cut and carved by laser to produce products with unique effects.
Hardness is one of the parameters that can best reflect the production process and technology of cast acrylic plate, and is an important part of quality control. Hardness can reflect the purity of raw material MMA, weather resistance and high temperature resistance of the plate. The hardness directly affects whether the plate will shrink, bend and deform, and whether the surface will be cracked during processing. Hardness is one of the hard indexes to judge the quality of acrylic plate. The cast acrylic plate has the highest hardness index at present, with an average Rockwell hardness of 90 degrees.
Acrylic board also has excellent weather resistance, especially for outdoor applications, ranking the top of other plastics, and has good surface hardness and luster. It has great processing plasticity and can be made into various required shapes and products. Its plates have a wide variety of colors (including translucent color plates), and another feature is that thick plates can still maintain high transparency.
