GPPS TPC-1160 for Extrusion
Product description:
GPPS TPC-1160 is a high heat resistance and molecular weight crystal polystyrene for extrusion and bioriented polystyrene(OPS) industry.It is particularlyuseful in the production of thick sheet by directinject gassing,where it gives expanded sheets with high mechanical properties.
GPPS1160 can also be used in dilution with HIPS7240 for extrusion of sheet for thermoforming.
Applications:
shower cabinets,lighting thin films,insulation board,foam sheet of fruits trays,meat trays,egg boxes.
