Thermosetting plastic
A thermosetting plastic, also known as a thermoset, is polymer material that irreversibly cures. The cure may be done through heat , through a chemical reaction , or irradiation such as electron beam processing.Thermoset materials are usually liquid or malleable prior to curing and designed to be...

Methacrylic acid
Methacrylic acid, abbreviated MAA, is an organic compound. This colourless, viscous liquid is a carboxylic acid with an acrid unpleasant odor. It is soluble in warm water and miscible with most organic solvents. Methacrylic acid is produced industrially on a large scale as a precursor to its...

 monomer (MMA) is polymethyl methacrylate (PMMA). MMA is a transparent and colorless fluid substance. One of the main characteristic features of PMMA is its high transparency. With its high weather resistance, it has been known to last over 30 years, it does not easily turn yellow or crumble when exposed to 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, bathtub liners, sinks, cell phone display screens, backlight optical waveguides for liquid crystal displays (LCD) and so on.
