Product Description: GP-32N is a general purpose polystyrene resin with easy flow and good It is recommended for applications where a specific balance of flow and strength are important. In injection molding, GP-32N possesses low viscosity at high shear rate. It is particularly suitable for glossy-layer co-extrusion.
Application:
- Injection molding
- Disposable cups
- Blending with HIPS
