Acrylic products are processed with acrylic sheets, acrylic plastic pellets, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resin, acrylic (latex) paint, acrylic adhesives and other products.
The acrylic products commonly used are made of acrylic pellets, plates or resins and other raw materials, and assembled with various materials and functional parts. Acrylic fiber, acrylic cotton, acrylic yarn, acrylic nylon, etc., which are commonly heard, are man-made fibers polymerized from acrylic acid and are not associated with acrylic products.
Among them, the acrylic sheet is often referred to as polymethyl methacrylate Polymeric Methyl Methacrylate (PMMA) sheet, which is polymerized by "methyl methacrylate monomer (Methyl Methacrylate (MMA)". Or extruded from acrylic pellets through a extruder. In the past, the plate was called plexiglass. Acrylic is derived from English acrylic, meaning PMMA board made of organic compound MMA, which has transparency and transparency like glass. Plates derived from all transparent plastics such as PS, PC, etc. or from inferior recycled MMA are collectively referred to as plexiglass. In order to distinguish, the PMMA board made of high quality pure material MMA is named as acrylic sheet to distinguish it from ordinary plexiglass board.

Hardness is one of the parameters that can reflect the production process and technology of pouring acrylic sheet, and 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 be cracked during processing. Hardness is one of the hard and good indicators for judging the quality of acrylic sheets. The cast acrylic sheet has a current high hardness index with an average Dyro hardness value of 90 degrees.
