TOTAL Polystyrene Crystal 1340

About
POLYSTYRENE CRYSTAL 1340 is a high molecular weight crystal polystyrene which allows maximum dilution rates with high impact polystyrene grades such as POLYSTYRENE IMPACT 7240. In dilution, POLYSTYRENE CRYSTAL 1340 gives excellent processing in both extrusion and thermoforming with good finished product dimensional stability and mechanical properties. POLYSTYRENE CRYSTAL 1340 can be used in injection. Applications Cups and other products by in line extrusion / thermoforming, foamed trays by direct gassing (in line thermoforming), dairy sheets, CD boxes, toys, office equipment, eggs boxes.&&
