Acrylic board has a crystal like transparency, with a light transmittance of over 92%. Acrylic board colored with dyes has good color development effect. In addition, acrylic board has excellent weather resistance, high surface hardness and luster, and good high-temperature resistance. Acrylic board has good processing performance and can be divided into two types according to production process: casting type and extrusion type. Both hot forming (including molding, blow molding, and vacuum molding) and mechanical processing methods such as drilling, turning, milling, cutting, etc. can be used. Mechanical cutting, scraping, and carving controlled by microcomputers not only greatly improve machining accuracy, but also produce more exquisite patterns and shapes than traditional methods. In addition, acrylic panels can be made using laser cutting and laser carving to create 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. The hardness can reflect the purity of raw material MMA, the weather resistance of the board, and the high-temperature resistance. The hardness directly affects whether the board will shrink, bend, and deform, and whether the surface will crack during processing. Hardness is one of the hard indicators for evaluating the quality of acrylic boards. The cast acrylic board has the highest hardness index at present, with an average Dalloch hardness value of 90 degrees.
Acrylic boards have excellent weather resistance, especially when used outdoors, ranking first among other plastics. They also have good surface hardness and luster, and have high processing plasticity, making them suitable for various shapes and products. There are various types of boards with rich colors (including semi transparent color boards), and another characteristic is that thick boards can still maintain high transparency.
