What is Polymethyl Methacrylate? ; Polymethyl Methacrylate Uses ;
Polymethyl methacrylate is a transparent thermoplastic that is often used as a replacement for glass in windows, eyeglasses, and other optical applications. It has a high impact resistance, meaning it doesn’t shatter easily, and is also very light. Polymethyl methacrylate is also nonflammable and can be tinted in a variety of colors.
Polymethyl Methacrylate Structure
Polymethyl methacrylate (PMMA) is a transparent thermoplastic often used in sheet or rod form as an alternative to glass. It has a higher impact resistance than glass and is less brittle. PMMA has a density of 1.19 grams per cubic centimeter and a melting point of 165 degrees Celsius.
Production of PMMA
PMMA is produced by the polymerization of methyl methacrylate. The polymerization is catalyzed by a free radical initiator, such as benzoyl peroxide.
Glass Substitute
Window glass is a type of glass that is made for windows. It is usually made of float glass, which is a type of glass that is made by floating molten glass on a bed of molten tin. Window glass is usually made with a greenish tint to reduce the amount of sunlight that is able to pass through it.
Healthcare Industry
The healthcare industry is in a constant state of flux as new treatments and technologies are developed, and as the Affordable Care Act (ACA) is implemented. The industry is also subject to government regulation and the ever-changing political landscape.

Solar Devices
Solar energy is the energy that is derived from the sun. It is an abundant and renewable resource that can be used to generate electricity, heat and cooling, and to power vehicles.
Solar cells, or photovoltaic (PV) cells, are the devices that convert sunlight into electrical energy. When sunlight shines on a solar cell, it creates an electric field across the cell’s layers. This electric field pulls electrons free from the atoms of the silicon material, allowing them to flow freely through the cell. When these electrons flow, they create an electric current.
The amount of electricity that a solar cell can produce is directly related to the amount of sunlight that shines on it. Solar cells can be made in a variety of sizes and shapes, and can be used to power everything from small electronic devices to large commercial and residential buildings.
Advantages of PMMA
Some advantages of PMMA include its optical clarity, durability, and strength. It is also non-toxic and non-flammable.
