Acrylic sheet process performance

Acrylic sheet has crystal-like transparency, and the light transmittance is more than 92%. Acrylic sheet colored with dye has a good color development effect. In addition, 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 and extrusion types according to the production process. Both thermoforming (including molding, blow molding and vacuum suction molding) can be used, as well as mechanical processing methods such as drilling, turning, washing, and cutting. The mechanical cutting and engraving controlled by a microcomputer not only greatly improves the processing accuracy, but also produces more exquisite patterns and shapes than traditional methods. In addition, the acrylic sheet can be laser cut and laser engraved to produce products with peculiar effects. Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheets, and it is an important part of quality control. The hardness can reflect the purity of the raw material MMA, the weather resistance and high temperature resistance of the sheet. The hardness directly affects whether the plate will shrink and bend, and whether the surface will crack during processing. Hardness is one of the rigid indexes to judge the quality of acrylic sheet. The cast acrylic sheet has the highest hardness index at present, and the average Darlow hardness value is 90 degrees. Acrylic sheet has excellent weather resistance, especially for outdoor use. It ranks first among other plastics. It also has good surface hardness and gloss. It has great processing plasticity and can be made into various shapes and products required. The board has a wide variety of colors and rich colors (including translucent color plates), and another feature is that the thick board can still maintain high transparency.
