Acrylic resin is a general term for any one of the plastics (resin) generated through chemical reaction by applying

The chemical name for the resin produced from the
Methyl methacrylatemonomer (MMA) is Polymethyl methacrylate (PMMA). MMA is a transparent and colorless fluid substance. [ [http://www.epa.gov/ttn/uatw/hlthef/methylme.html Methyl Methacrylate] epa.gov, 2000, 'a colorless, volatile, flammable liquid that is soluble in warm water'] One of the main characteristic features of PMMA is its high transparency. With its high weather resistance, it does not easily turn yellow or crumble by sunlight. Polymethyl methacrylate are used not only for transparent windows in aquariums but also for various items such as signboards in places like convenience stores, taillights of automobiles, cell phone display screens, backlight optical waveguides for liquid crystal displays(LCD) and so on.
