Pellets for injection molding are made either by bulk polymerization of methyl methacrylate followed by extrusion and pelletization or by polymerization in an extruder. Formulations vary by molecular weight and physical properties such as flow rate, heat resistance, and toughness.

What is Acrylic (PMMA), and What is it Used For? Acrylic is a transparent thermoplastic homopolymer known more commonly by the trade name “plexiglass.” The material is similar to polycarbonate in that it is suitable for use as an impact resistant alternative to glass (particularly when the high impact strength of PC is not required).

Injection Molding Machines; PMMA has no special requirements for injection molding machines. Because of its high melt viscosity, it needs a deeper spiral groove and a nozzle with larger diameter hole.
