ANULON-120 Polymethyl Methacrylate (PMMA)

Back

ANULON-120 Polymethyl Methacrylate (PMMA) commonly known as Acrylic due to its high clarity (92% light transmission) and toughness is widely used for various optical applications, such as, transparent covers, domes, level indicators, gauge glass, laboratory apparatus, test jigs etc. ANULON-120 is chosen for many applications because of a unique combination of properties, such as, crystal clarity, good surface hardness, exceptional weatherability, chemical and environmental resistance, and excellent mechanical stability. It exhibits low electrical conductivity and good arc resistance and dielectric strength.
