Material Notes:
OROGLAS MI-4T is an acrylic grade that associates improved impact resistance with high heat resistance.Key features improved impact resistance: up to 4 times more impact resistant than standard acrylics. outstanding thermal resistance: HDT A (1.82 MPa) = 98°c. good flow and processing behavior. UV stability. clarity, brilliance and excellent optical properties. Typical applications OROGLAS MI-4T can be injection molded or extruded to produce technical items mainly for automotive and lighting markets.ISO data provided by the manufacturer, Arkema.Arkema, formed in 2004, was formerly Atofina Chemicals and before that Elf Atochem.
