Acrylic is suitable for secondary processing, such as mechanical processing, thermoplastic molding, blow molding, blister molding, solvent gluing, heat printing, screen printing, and vacuum plating. After successful completion, it is what we call acrylic lenses. . Mirrors made of acrylic are not fragile, and the base material is PMMA. Hong Kongers and Taiwanese also call them pressure-accented lenses, and acrylic lenses, which actually refer to the general term for electroplated PMMA plates. Plastic lenses are used instead of glass. The lenses have the advantages of being light in weight, not easily broken, easy to mold and process, and easy to color. Their development momentum is increasing day by day, and they have become a first-class technology in lens production. Plastic sheets can generally be made into: single-sided mirrors, double-sided mirrors, plastic mirrors, paper mirrors, semi-lenses, etc., which can be made according to different requirements. Acrylic panels are polymerized from methyl methacrylate monomer (MMA), which is polymethyl methacrylate (PMMA) sheet organic glass. It is a kind of organic glass processed through a special process. It is known as the "Plastic Queen". The research and development of acrylic has a history of more than 100 years.
