polüetüülmetakrülaat

Polüetüülmetakrülaat, often abbreviated as PEMA, is a synthetic polymer belonging to the methacrylate family. It is a thermoplastic material derived from the polymerization of ethyl methacrylate monomers. PEMA is known for its clarity, rigidity, and good resistance to weathering and UV radiation. Its chemical structure features a repeating unit of ethyl methacrylate, characterized by an ester group and a vinyl group.

This polymer finds various applications due to its desirable properties. In the medical field, PEMA is utilized in the formulation of bone cements and dental prosthetics. Its biocompatibility and ability to be molded into complex shapes make it suitable for these uses. PEMA also serves as a component in certain types of adhesives and coatings, where its durability and transparency are advantageous. In the optical industry, its high refractive index and clarity contribute to its use in lenses and other optical components. PEMA can be processed using standard thermoplastic techniques such as injection molding and extrusion. It is generally considered safe and stable under normal conditions of use.
