Acrylic - In the plastics industry most acrylics are polymers of methyl methacrylate (PMMA). Poly(methyl methacrylate) (PMMA) is a transparent thermoplastic, often used as a lightweight or shatter-resistant. The most important properties for acrylic (PMMA) are its optical clarity, low UV sensitivity, and overall weather resistance. Acrylic is often used as a glass substitute.
Although it is not technically a type of glass, the substance has sometimes historically been called acrylic glass. Chemically, it is the synthetic polymer of methyl methacrylate.
A rigid thermoplastic sign material available in transparent, translucent and opaque appearances. Acrylic sheet can be clear or produced in a variety of color tones. Acrylic that is manufactured by pouring a molten compound into a thin compartment and curing it under heat and pressure is said to be CELL CAST. Acrylic manufactured by casting a liquid compound between moving stainless steel plates that exert heat and pressure is said to be CONTINUOUS CAST.
Acrylics may be in the form of molding powders or casting syrups, and are noted for their exceptional clarity and optical properties. Acrylics are widely used in lighting fixtures because they are slow-burning or even self-extinguishing, and they do not produce harmful smoke or gases in the presence of flame.
