Material Notes:

Polystyrene 680 is a medium impact polystyrene developed for the foam extrusion and laminate markets. This polymers impact qualities in conjunction with its high flexural strength allow 680 to be extruded for foam laminates and film. Applications using crystal polystyrene that require some impact without extreme clarity, such as window envelope film, should consider 680. 680 also excels as an OPS modifierInformation provided by Total Petrochemicals, Inc.
