FAQ | Color Masterbatch Knowledge Base

Color masterbatch is a concentrated pigment mixture dispersed in a carrier resin. It is added to base resin during plastic processing (film extrusion, injection molding, fiber spinning, etc.) to impart color. Typical let-down ratios range from 1% to 5% depending on color depth, opacity requirements, and application. The carrier resin should be compatible with the base polymer to ensure good dispersion and mechanical properties.

Masterbatch offers several advantages over direct pigment use: easier handling and dosing, better dispersion quality, cleaner production environment, and the ability to combine color with functional additives (UV stabilizers, antioxidants, slip agents, etc.) in a single product.

Yes. We offer comprehensive custom color matching services. You can provide us with any of the following:

Physical sample: A plastic part, film sample, or color chip
Pantone number: We can match to Pantone Matching System (PMS) codes
RAL code: European RAL Classic color standard
Spectral data: CIE L*a*b* values from your spectrophotometer

Our R&D team will develop a matching formulation within 5–7 working days. We use advanced spectrophotometry to ensure color consistency, with color difference (ΔE) controlled below 1.0. Sample production runs of 25 kg are available for your testing before placing a full order.

The standard MOQ varies by product type:

Stock items (standard colors): 500 kg per color
Custom color formulations: 1,000 kg per color
Trial samples: 25–50 kg for testing (sample rate applies, creditable toward first order)

For established customers with regular orders, lower MOQs may be negotiated. Please contact our sales team to discuss your specific requirements.

Yes. Our food-contact grade masterbatch complies with the following international regulations:

FDA 21 CFR Parts 174–178 — U.S. food contact regulations
EU 10/2011 — European food contact plastic regulation
GB 4806 — China food contact material standard
REACH (EC No 1907/2006) — EU chemical registration
RoHS — Restriction of hazardous substances

Relevant compliance documentation, including Safety Data Sheets (SDS) and Certificate of Analysis (COA), is available upon request. Third-party test reports from SGS or TÜV can also be provided for specific products.

Production lead time:

Standard products: 10–15 working days after order confirmation
Custom color matching: additional 5–7 working days for formulation
Large orders (>5 tons): may require extended production time, confirmed at order placement

Shipping times (from Changsha, China):

Sea freight to Europe: 25–35 days
Sea freight to North America: 25–35 days
Sea freight to Southeast Asia: 10–15 days
Air freight (urgent orders): 5–7 days

We provide tracking information and regular shipment updates. FOB Changsha or CIF destination port terms available.

We offer masterbatch with various carrier resins to ensure compatibility with your base polymer:

PET — for BOPET film, polyester fiber
PP — for BOPP film, PP injection, PP fiber
PE (LDPE/HDPE) — for blown film, cast film, injection
PA (Nylon) — for BOPA film, nylon fiber
PLA / PBAT / PBS — for biodegradable applications
PS / ABS — for injection molding applications

We select the carrier resin based on compatibility with your base polymer and processing method. If you have a specific resin requirement, please let us know.

Color consistency is maintained through a multi-layer quality control system:

Computerized color matching: Spectrophotometry using CIE L*a*b* color space
Batch-to-batch QC: Color difference (ΔE) monitored and controlled ≤ 1.0
Raw material control: Standardized sourcing from approved suppliers with incoming inspection
Process monitoring: Automated production lines with real-time temperature and speed control
Final testing: Each batch is tested before shipment, with COA provided

For long-term customers, we retain master samples to ensure continuity across repeat orders.

Yes. Our technical team provides comprehensive support:

Let-down ratio optimization for your specific application
Processing temperature and speed recommendations
Troubleshooting for color dispersion issues (streaks, fish eyes, uneven color)
Film/product sample analysis and testing
On-site technical visits for key accounts
