Introduction of optical grade acrylic sheet

Hardness is one of the parameters that can reflect 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 crack during processing. Hardness is one of the rigid indicators for judging the quality of acrylic sheets. The cast acrylic sheet has the current hardness index with an average Darrowell hardness value of 90 degrees.

Optical grade acrylic sheet has crystal-like transparency, and the light transmittance is more than 92%. Acrylic sheet colored with dyes has a good color development effect. In addition, acrylic sheet: has weather resistance, high surface hardness and surface Gloss and good high temperature resistance. Acrylic sheet has good processing properties, and can be divided into two types: casting type and extrusion 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, cutting, etc. 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 patterns and shapes than traditional methods. In addition, the acrylic sheet can be laser cut and laser engraved to produce products with peculiar effects.

All kinds of acrylic panels are changing their appearance and appearing in our lives. In recent years, acrylic panels of various colors are appearing in our lives, and there are more and more patterns. Because the acrylic sheet is non-toxic and environmentally friendly, it is even more loved by me. The processing function of acrylic sheet is very good, cutting or injection molding is very convenient. Acrylic board itself has excellent angle and gloss, and maintenance is very easy. Many acrylic board artworks are portrayed and placed in our lives, adding beauty to us. Acrylic is the best new material that can be used to create sanitary ware following ceramics in the future. As a special kind of inorganic glass, acrylic can also be used for sun-shading glass and has been used for ten years under harsh conditions.
