Polystyrene 503: Is a very high flow, high heat crystal polystyrene. The very low viscosity of this grade combined with its high heat resistance makes it particularly suitable for the production of extrusion foam board (XPS) with blowing agents such as CO2 and HFC. It is also ideal for use as a masterbatch carrier. Application:
Melt Flow Index (MFI) at 230°C / 2.16 kg, density, polymer melting point and tensile strength. The full Technical Data Sheet (TDS) is available on request.
Suited to injection moulding and forming applications such as rigid containers, caps and engineering parts that demand high stiffness and dimensional stability.
