General purpose polystyrene GPPS 1077 is manufactured by continuous mass polymerization of styrene monomer. It is a high melt flow; high heat crystal polystyrene designed for fast cycle injection moulding. It is also designed for high output, direct injection profile extrusion for foam applications.
It is recommended for houseware, containers, drinking cup, tableware, optical parts, plastic bangles, cosmetic packing parts, stationery products, foam boards and wood replacements
