Silk Finish for PLA Filament Buyers: Masterbatch Fundamentals
For PLA filament distributors also needing color masterbatch, understanding masterbatch basics from a filament buyer perspective is valuable. Our company produces both filament and masterbatch, making us a dual-source supplier.
What Is PE PP Color Masterbatch?
Concentrated pigment in carrier resin for coloring plastics during injection molding. Our Universal White for PE/PP: 70% TiO2 in PE/PP carrier. For injection/blow molding, not 3D printing. Filament buyers who also mold parts can source both from one supplier.
How Masterbatch Relates to Filament
In filament, colorants are PLA-specific formulations. PE PP masterbatch is for injection molding with different carrier. Color matching expertise applies to both.
| Product | Application | MOQ |
|---|---|---|
| PLA Filament | 3D printing | 200 spools |
| Color Masterbatch | Injection molding | 2 metric tons |
Universal White Specifications
70% TiO2, 2-4% let-down, L* 96.5 on PP, yellow index below 2.0. PE/PP compatible. Stable to 230 C. 25 kg bags. MOQ 2 tons, 10-12 days. COA per batch.
Color Matching Across Products
Same lab, same colorimetric standards (L*, a*, b*, Delta E). Pantone/RAL for both. Buyers benefit from cross-product expertise.
Combined Sourcing
Single contact, consolidated shipping, consistent colors, unified compliance, volume pricing across lines.
Quality Standards
Both: spectrophotometric verification, COA, retained samples, compliance. Filament: ±0.02 mm. Masterbatch: TiO2, MFI, moisture, colorimetric.
