| Comparison Aspect | SAN (NV220F) | ABS |
| Transparency | High (transparent) | Opaque |
| Impact Strength | Medium | High |
| Cost | Lower | Higher |
| Surface Gloss | Excellent | Good |
Conclusion: If transparency is critical, SAN is the better choice; for higher impact resistance, ABS is preferred.
| Comparison Aspect | SAN | PP |
| Rigidity | High | Medium |
| Transparency | High | Low |
| Heat Resistance | Higher | Medium |
| Cost | Medium | Low |
Conclusion: SAN is better for applications requiring appearance and rigidity, while PP is suitable for budget-sensitive projects.
1. Drying Conditions (Drying Temp)
80–90°C for 2–4 hours
A dehumidifying dryer is recommended to prevent bubbles and silver streaks
2. Injection Temperature
Barrel temperature: 200–250°C
Nozzle temperature: 210–230°C
3. Mold Temperature
40–70°C
4. Processing Notes
Avoid prolonged high-temperature residence to prevent material degradation
Medium to high injection speed is recommended to improve surface gloss
Ensure uniform cooling to reduce internal stress
Q1: Can NV220F SAN be used for food contact applications?
A: It is generally suitable for non-direct food contact applications. Compliance with local regulations (such as FDA or EU standards) should be verified.
Q2: Why do silver streaks or bubbles appear during processing?
A: This is mainly caused by excessive moisture content. Proper drying and the use of a dehumidifying dryer are recommended.
Q3: What is the difference between SAN and PS (Polystyrene)?
A: SAN offers higher strength, better heat resistance, and improved chemical resistance compared to PS, making it suitable for more demanding applications.
Q4: Is NV220F suitable for thin-wall products?
A: Yes, its good flowability (higher MFR) makes it ideal for complex structures and thin-wall injection molded parts.
