Yellow Pigments for Polymer Coloring

The Global Source for Plastic-Grade Yellows

Deqing Demi Pigment Technology Co., Ltd. is a leading provider of high-performance yellows for the polymer industry. We understand that in plastics, color is only half the battle; the pigment must also maintain the physical properties of the plastic. Our yellows are processed to be "Low-Warping," making them ideal for large, flat plastic parts like crates and panels. We support masterbatch producers and plastic molders globally with pigments that offer the perfect balance of color strength, heat stability, and cost-efficiency.

Polymer Coloring Applications

• Injection Molding: High-precision coloring for consumer goods and toys.
• Plastic Crates & Pallets: Durable yellow for industrial logistics products.
• PVC Profiles: UV-stable yellow for window frames and siding.
• Fiber Extrusion: Fine-particle yellows for synthetic textiles and turf.

Polymer Yellow Technical Specs

Performance Characteristics

• Non-Warping: Does not cause dimensional distortion in semi-crystalline plastics.
• Easy Dispersion: Rapidly incorporates into polymer melts with low shear.
• Excellent Opacity: Provides high hiding power for thin-walled plastic parts.
• Food Contact Safety: Specific grades comply with global food safety regulations (FDA/EU).

• Q: Will the yellow turn orange during injection molding?

  A: Standard yellow oxides can turn orange at high heat. For high-temp molding (>200∘C), we recommend our Zinc Ferrite or surface-stabilized yellow series.

• Q: Does it affect the impact strength of the plastic?

  A: No, our fine-particle yellows are designed to integrate without creating "stress risers" in the polymer matrix.

Precision Masterbatch Services

We provide "High-Loading" pigment concentrates to help masterbatch producers optimize their production throughput.

Shrinkage Testing: Our lab offers "Mold Shrinkage" analysis to prove that our pigments will not cause dimensional inaccuracy in your specific plastic part design.

The Science of Thermal Stability

In polymer yellows, we focus on "Crystal Dehydration." We use TGA (Thermogravimetric Analysis) to measure the temperature at which the pigment begins to lose its hydroxyl groups. By stabilizing the crystal surface, we move the "Reddening Point" higher, ensuring the yellow stays vibrant through the molding nozzle. We monitor the CIELab Delta E after multiple "Heat-Cool" cycles to guarantee that the final consumer product matches the design specification.
