Very easy flow general purpose polystyrene.

Used for injection of thin-wall, multi-cavity, very fast-cycle mouldings and for sheet extrusion in glossy capping of HIPS and in blend with HIPS or clear SBS.

Designation: Thermoplastics ISO 1622-PS,G,085-20

Applications
Typical uses include cups, packaging containers for foods and cosmetics, toys, medical articles.
Thanks to its high flow it is particularly suitable as carrier for master batches.
