General Purpose Polystyrene GPPS G32N
Description: Polystyrene GP-32N is a general-purpose polystyrene resin with easy flow and good clarity. It is recommended for applications where a specific balance of flow and strength are important. In injection molding, GP-32N possesses low viscosity ot high shear rate. It is particularly suitable for glossy-layer coextrusion.
Typical applications:
- Injection molding
- Disposable cups
- Blending with HIPS
