What is acrylic?
Jul 11, 2018
Acrylic products include acrylic sheets, acrylic plastic pellets, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resin, acrylic (latex) paint, acrylic adhesives, etc., and a wide variety.
Acrylic products, which are now 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 related to 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 commonly called plexiglass.
Acrylic means a PMMA board made of MMA of an organic compound, which has transparency and transparency like glass. All the plates made of transparent plastics such as PS, PC, etc. or by inferior recycled MMA are collectively referred to as plexiglass. For the sake of separation, the PMMA board made of high-quality pure material MMA is always referred to as an acrylic sheet, and is separated from the general plexiglass board
Acrylic material feature
1. Thickness Acrylic Tolerance: Acrylic sheet thickness has acrylic tolerance, so the control of acrylic tolerance is an important embodiment of quality management and production technology. Acrylic production has an international standard ISO7823 casting plate tolerance requirements: tolerance = ± (0.4 + 0.1 x thickness) tolerance requirements for extruded plates: tolerance = < 3 mm thickness: ± 10% > 3 mm thickness: ± 5% 3. Transparency/Whiteness: Strict raw material selection, advanced formula follow-up and modern production process ensure excellent transparency and whiteness of the board. After the flame is polished, it is crystal clear.
2. Hardness: Hardness is one of the parameters that best reflects the production process and technology of casting acrylic sheet, and is an important part of quality control. The hardness can reflect the purity of the raw material PMMA, 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, and the average Dalhou hardness value is about 89 degrees.
