Description
GPPS 1160
General purpose polystyrene
Product Description
GPPS1160 is a high heat resistance and molecular weight crystal polystyrene for extrusion and bioriented polystyrene (OPS) industry. It is particularly useful in the production of thick sheet by direct inject 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.

Density and shrinkage of this grade are approximately around 1.04 kg/lit & (0.4-0.7) % (ASTM D-955) respectively. All tests are carried out at 23°C, unless otherwise stated.
If in grade reference the fourth digit is “1”(1161), indicates an external lubricant is included.
If the injection molding products quality is affected by moisture, granules of GPPS could be dried at 70C for 2-4 hours.
