What is acrylic sheet?

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 appearance Gloss and good high temperature resistance. Acrylic sheet has outstanding processing performance, and can be divided into casting type and kneading type according to the production process. Both thermoforming (including compression molding, blow molding and vacuum suction molding) can be used, and mechanical processing methods such as drilling, turning, washing, and cutting can also be used. The mechanical cutting and engraving controlled by a microcomputer not only greatly improves the processing accuracy, but also produces more exquisite pictures and shapes than traditional methods. In addition, the acrylic sheet can be cut and engraved by laser to make products with unique functions.

Hardness is one of the parameters that best reflects the production process and technology of cast acrylic sheet, and it 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 appear to be cracked during processing. Hardness is one of the hard targets for judging the quality of acrylic sheets. The cast acrylic sheet has the highest hardness target now, with an average Darlow hardness value of 90 degrees.

Acrylic sheet has excellent weather resistance. It is especially used outdoors and ranks first among other plastics. It also has outstanding surface hardness and gloss. It has great processing plasticity and can be made into various required shapes and products. The board has a wide variety of colors and rich colors (including translucent swatches), and another feature is that the thick board can still maintain high transparency.
