General Purpose Polystyrene 1540
GPPS 1540 is an easy-flowing crystal polystyrene designed for both extrusion and injection applications. When combined with a super high-impact polystyrene like HIPS7240, it enhances extruder output and thermoforming cycle times. Notably, GPPS 1540 offers excellent fluidity and a higher softening point compared to GPPS 1810/1811 grade.
Applications of GPPS 1540
GPPS 1540 finds versatile applications:
- Extrusion:
- Impact dilution
- Gloss layer in co-extrusion
- Anionic styrene butadiene copolymer dilution
- Injection:
- Packaging articles
- Medical applications (e.g., petri dishes)
- Office equipment
- Pen barrels
- Crisper boxes for refrigerators
- Cups
