Acrylic polymer, derived from the monomer methyl methacrylate (MMA), was first developed more than 60 years ago. Since then, formulations have extended the material’s performance range, resulting in varying levels of melt flow, impact resistance, colorability, gamma recovery, and other controlled characteristics. General-purpose acrylic grades contain a comonomer, added during the polymerization process, to facilitate flow during injection molding and extrusion. Specialty grades are formulated to perform in applications requiring high impact strength and heat resistance. UV-light-transmitting formulations are also available, and are specified for certain critical diagnostic equipment in which even slight UV absorption or variation in material flow […]
