Expandable Polystyrene - Technology Benefits
At the heart of INEOS Technologies’ expandable polystyrene suspension technology is the reactor which contains a proprietary agitator and baffle system for ensuring excellent mixing and temperature control. Together with a reduced temperature chemically initiated polymerisation, this results in both significantly improved and more consistent polymer properties.
Other significant advantages of the technology include:
- The robust mineral suspension system developed in-house minimizes water consumption. This provides a narrow bead size distribution allowing a very high prime rate and easy market supply.
- An optimised drying system that ensures no degradation in product quality before screening and coating.
- A proprietary continuous coating system that repeatedly demonstrates consistent and dust free products.
- An optional pentane recovery unit that achieves the best pentane yields on the market and matches all current and future VOC emission regulations.
- Safe and environmentally clean operation.
With the collective experience of commercially proven operation and ongoing process developments, single lines featuring up to four reactors have now reached a capacity of 100 ktpa which is the highest capacity on the market for a single swing line producing both FR & Regular polystyrene grades. This provides the ability to deliver an unparalleled return on investment.
