GPPS

GPPS (General Purpose Polystyrene) is a rigid, clear, cost-effective thermoplastic that processes easily and holds dimensional stability well, though without the impact resistance of HIPS. We stock a range of grades from Dioki and Estyrenics spanning low to high melt flow, for packaging, disposable products and general moulded components.

GPPS DIOKI 610 MFI 11

A high-flow general-purpose polystyrene grade from Dioki with an MFI of around 11, suited to fast-cycling, thin-walled and intricate mouldings.

Typical propertiesMFI approximately 11 g/10min; good clarity and rigidity typical of GPPS; easy processing at higher flow.
ApplicationsThin-wall packaging, disposable items, general moulded components requiring fast fill.

GPPS ESTYRENICS 123 MFI 10

A general-purpose polystyrene grade from Estyrenics, the Egyptian polystyrene and styrene monomer producer, with an MFI of around 10 — a versatile mid-flow grade suited to a broad range of standard GPPS applications.

Typical propertiesMFI approximately 10 g/10min; representative clarity, rigidity and stiffness for a general-purpose GPPS grade.
ApplicationsPackaging, disposable tableware, appliance and electronic components.

GPPS DIOKI 603 MFI 3

A lower-flow general-purpose polystyrene grade from Dioki with an MFI of around 3, offering greater melt strength for thicker-walled parts and applications needing more consistent flow control.

Typical propertiesMFI approximately 3 g/10min; higher melt strength than higher-flow GPPS grades; representative rigidity and clarity for this grade family.
ApplicationsExtrusion, thicker-section mouldings, general-purpose components requiring more melt strength.
