Color Masterbatch Deodorizer

Product Introduction

As the core intermediate for plastic coloring, the hue accuracy of masterbatch dictates its commercial value. During the high-temperature and high-shear twin-screw extrusion process, high-concentration organic pigments easily decompose, releasing pungent sulfur and nitrogen volatile odors. Meanwhile, carrier resins age, producing rancid aldehyde/ketone smells. Traditional deodorizers often overuse low-molecular-weight dispersants causing surface "blooming" and "color floating", or abuse inorganic fillers that dilute pigment saturation, turning the hue milky. Additionally, moisture from porous carriers can cause strand breakage during pelletizing.

To thoroughly bridge the technical gap of "optical transparency" and "rheological compatibility", this product is a reactive dry-blend additive custom-designed for high-concentration color masterbatch. It completely excludes easily precipitating low-molecular organics and high-refractive-index fillers. By introducing "macromolecular homologous anchoring and nanoscale optical invisibility" dual-core technology, it precisely captures pigment stench and catalytically decomposes resin aging odors without interfering with the conjugated chromophore system. Through thermodynamic chemical bonding and physical co-crystallization, it achieves true "zero blooming, zero color floating." Its ultra-hydrophobic nanoscale coating prevents moisture-induced strand breakage and ensures ultimate powder flow and dispersion, eliminating color spots and preserving the original hue and gloss.

Deodorizing Principle

• Empty Orbital Targeted Complexation: Active components feature electron-deficient metal coordination centers. Upon heating, they actively hunt pigment degradation products (free amines, sulfides), using empty orbitals to form rapid, irreversible coordinate bonds. This permanently converts odors into stable networks without destroying pigment chromophores.
• Acid/Base Neutralization & Catalytic Cracking: Built-in metal oxides act as strong acid absorbers and catalysts, instantly neutralizing fatty acids from resin thermal aging and catalytically cracking stubborn aldehydes/ketones, cutting off odor regeneration.
• Macromolecular Homologous Anchoring: Introduces a compatible medium with polar reactive ends and ultra-long polyolefin chains. The polar ends bite into the reacted deodorizing products, while the non-polar long chains achieve 100% homologous co-crystallization with the carrier resin. This securely locks polar components, preventing blooming and color floating.
• Nano Water-Repellency & Optical Invisibility: Encapsulated by a dense nanoscale ultra-hydrophobic network. Its particle size is smaller than visible light, achieving true "optical invisibility" without diluting color. Its absolute water-free nature prevents strand breakage, and acts as "microscopic ball bearings" to ensure ultimate dispersion.

Application Areas

• Organic Pigment Masterbatch: Highly effective for high-concentration masterbatches containing easily degraded pigments like Azo Red/Yellow or Phthalocyanine Blue/Green, locking in odors without color shift.
• General & Engineering Masterbatch: Ideal for high-end injection, extrusion, and blown film masterbatches using PE, PP, EVA, ABS, or PS as carrier resins.
• High-Standard Eco-Friendly Coloring: Dedicated to coloring systems with extremely strict requirements on heavy metals, halogens, and odors, such as food-contact packaging, medical injection parts, and children's toys.

Usage Method

• Adding Method: A ready-to-use dry powder additive. Add it along with pigment powder and carrier resin into the mixing equipment during the masterbatch compounding stage.
• Mixing Requirements: Thanks to its outstanding nanoscale self-lubricating technology, it disperses easily. While a high-speed mixer is recommended for best results, it is fully compatible with standard V-type or drum mixers at low/medium speeds.

Reference Dosage

• Standard Color Masterbatch: Add at 1.0% - 1.5% of the total masterbatch weight (since masterbatch is concentrated, the deodorizer must be added proportionally).
• Heavy Odor Masterbatch: Add at 1.5% - 2.0%.
• Starting Test Dosage: Start pelletizing at 1.0%. Then, dilute the masterbatch for injection or blown film, and fine-tune based on the final product's odor standard and color performance.

Precautions

• Moisture Sealing: Despite nanoscale hydrophobic treatment, its huge surface area means any unused product must be sealed immediately. Prolonged exposure to high humidity may affect its ultimate dispersion.
• Temperature Compatibility: Recommended twin-screw extrusion temperature is between 160°C - 280°C. Within this wide range, it maintains excellent thermal stability for high-shear pelletizing.
