Masterbatch Application Scenarios
1. Consumer Electronics Housings
Typical Polymers: ABS, PC/ABS, HIPS
CR-1220's Role:
- Provides the premium "tech white" appearance demanded by high-end devices
- Maintains color stability under UV exposure (Class B weatherability)
- Enables thin-wall molding without flow marks or uneven coloration
Usage Recommendations:
- Recommended let-down ratio: 1:20 to 1:30 for optimal cost/performance
- Combine with UV stabilizers for outdoor electronics applications
- Pre-dry masterbatch at 80°C for 2 hours when processing hygroscopic polymers
2. Food Packaging Masterbatch
Typical Polymers: PP, HDPE
CR-1220's Role:
- Delivers FDA-compliant whiteness for food contact applications
- Provides excellent opacity to protect contents from light degradation
- Maintains polymer mechanical properties at high loadings
Usage Recommendations:
- For thin-wall packaging, use 1:50 let-down ratio to maintain clarity
- Combine with anti-block agents to prevent sticking in film applications
- Process at 200-220°C for PP to optimize dispersion
3. Automotive Interior Components
Typical Polymers: PP, TPO, ABS
CR-1220's Role:
- Withstands long-term UV exposure without yellowing
- Provides consistent color matching across different polymer substrates
- Resists abrasion and scratching in high-wear areas
Usage Recommendations:
- For instrument panels, use 2-3% masterbatch concentration
- Combine with heat stabilizers for components near heat sources
- Ensure melt temperature exceeds 220°C for optimal dispersion in TPO
Masterbatch Processing Guidelines
Optimal Processing Parameters
| Melt Temperature | 200-240°C |
| Screw Speed | 60-80% of maximum |
| Back Pressure | 50-80 bar |
| Screw L/D Ratio | ≥25:1 |
Troubleshooting Guide
| Issue | Solution |
| Uneven dispersion | Increase melt temperature by 10-15°C |
| Color streaks | Check screw wear, increase back pressure |
| Yellowing | Reduce residence time, verify thermal stabilizers |
