Material Notes:
Polystyrene 740 is an impact polystyrene designed for extrusion and injection molding. It is especially suitable for extrusion thermoforming applications requiring high glass and high stiffness, such as food service disposable. A unique combination of thermal characteristics favors 740 for fast injection cycles in high gloss small appliance and electronics application.Information provided by Total Petrochemicals, Inc.
