General purpose polystyrene
Product Description
GPPS 1460 is a high heat resistance and molecular weight crystal polystyrene for extrusion and thick walled injection moulding application.
It is particularly useful in the production of thick sheet by direct inject gassing,where it gives expanded sheets with high mechanical properties.
Applications:
insulation board(xps), foam sheet of food & fruits trays
