Custom color masterbatch / Yuyao, China / Since 2007
Custom color built around your resin and process.
Sinfone develops custom color masterbatch from a real color reference and the conditions that shape the final result: base resin, processing method, end use, and required appearance. Standard white and black grades are also available when they fit the project.

Core capability and reference grades
Custom color first, standard grades when they fit.
Most projects begin with a color target and the production conditions behind it. When a standard white or black grade is the better starting point, we can review that path as well.

Process before product
A better masterbatch conversation starts with your production reality.
A shade alone is not enough. Carrier choice, dispersion, opacity, compatibility, and final appearance all depend on the base resin, processing route, loading expectations, and end application. We use those inputs to decide whether a standard grade or a custom path is the better place to start.
How an inquiry moves
From a clear input to a useful sample discussion.
Early accuracy matters more than generic promises. These are the three inputs that help us review fit efficiently.
Define color and end use
Share white, black, or custom color direction plus the final part, film, housing, cable, packaging, or other application.
Review sample and support
After fit is confirmed, we can discuss samples and the supporting technical or third-party documents relevant to the grade.
Buyer questions
The essentials, answered directly.
What masterbatch products does Sinfone currently offer?
Our main capability is custom color masterbatch developed around the buyer's color reference, resin, process, and end use. We also introduce standard white grades 3450 and 3125 and black grade 2016 when those products fit the requirement.
Which plastics processes can you review?
Company materials describe work across injection molding, blown film, blow molding, extrusion, rotational molding, wire drawing, and calendering. Final fit depends on the resin system, process conditions, and required end performance.
What should I send with a new inquiry?
Please include the target resin, processing method, end application, white or black requirement, or a reliable custom color reference. Any known loading, tolerance, testing, or documentation need is also helpful.
Can you arrange samples and supporting documents?
Samples can be discussed for project review. Relevant certificates, reports, and technical information can also be provided when they match the product grade and application under discussion.
How does custom color matching begin?
The best starting point is an approved physical sample, plaque, pellet, chip, swatch, or recognized color-card reference, together with the target resin and processing method.
