Masterbatch FAQ
What is the recommended dosage of masterbatch for optimal results?
The typical dosage ranges from 1% to 5% depending on the desired color intensity or additive effect. For standard coloring applications, we recommend starting with 2% masterbatch concentration and adjusting based on your specific requirements.
How should masterbatch be stored to maintain quality?
Masterbatch should be stored in a cool, dry place away from direct sunlight at temperatures between 10°C and 30°C. Keep containers tightly sealed when not in use to prevent moisture absorption. Under proper conditions, our masterbatches maintain stability for 24 months from production date.
Can different types of masterbatch be mixed together?
While technically possible, we generally advise against mixing different masterbatches unless specifically recommended. Incompatible carrier resins or additives may cause processing issues or affect final product properties. For custom formulations, consult our technical team for guidance.

Additional Masterbatch FAQ
What's the difference between universal and custom masterbatch?
Universal masterbatches are pre-formulated for broad applications with standard color shades, while custom masterbatches are specifically developed to meet unique requirements regarding color, effect, or performance characteristics in particular polymer systems.
How does masterbatch compare to liquid colorants?
Masterbatch offers superior handling characteristics, better dispersion in most processes, and doesn't require special liquid dosing systems. It provides more consistent results in high-volume production and eliminates issues with evaporation or viscosity changes.
What quality certifications do your masterbatches have?
Our production facilities maintain ISO 9001 certification, and specific product lines comply with FDA, EU 10/2011, and REACH regulations. We can provide documentation for compliance with various industry standards upon request.
Masterbatch Selection Guide
Choosing the right masterbatch involves considering:
- Base polymer type and grade
- Processing conditions (temperature, shear rates)
- End-use requirements (UV resistance, food contact, etc.)
- Desired aesthetic or functional properties
- Regulatory compliance needs
Final Masterbatch FAQ
How do you ensure color consistency across production batches?
We implement rigorous quality control including spectrophotometric measurements against master standards, precise raw material weighing systems, and documented production parameters. Each batch undergoes thorough testing before release.
What's the lead time for custom masterbatch development?
Standard custom formulations typically require 2-4 weeks including lab trials, approval samples, and production scale-up. Complex projects may take longer depending on technical challenges and testing requirements.
Can masterbatch be used in biodegradable plastics?
Yes, we offer specialized masterbatches compatible with PLA, PBAT, and other biodegradable polymers. These formulations maintain compostability while providing excellent coloration and processing characteristics.
