Thermoplastic PMMA is created by heating up the plastic until it becomes pliable. It is a synthetic polymer which is acrylic and most commonly referred to as Plexiglass. It is used in the making of lenses, helmet visors, and airplane windows.

"Made of" and "Made from" can mean the same thing. "That can is made from aluminum." "That can is made of aluminum." However, they can't be used the same in every situation. You can say: "That house is made of wood and made from workers." But you can't say: "That house is made of workers and made from wood."
PMMA is a synthetic material, made through a polymerization process of methyl methacrylate monomers. It is not naturally occurring in nature.
Acrylic, or poly (methyl methacrylate) (PMMA) is a compound made op from carbon, oxygen and hydrogen. Acrylic paint is not a compound but an suspension of PMMA in water. However, PMMA is hydrophobic and so other compounds need to be added to enable the suspension to form.

PMMA (polymethyl methacrylate) is transparent because its molecular structure allows light to pass through easily without significant scattering or absorption. The repeating methyl methacrylate units in PMMA align in a regular pattern, which helps minimize light distortion and enhances transparency.
