Explore our core product lines manufactured with high-concentration pigments, superior non-migration chemistry, and certified thermal stability.
Deconstructing the Micro-Physics of Pigment Agglomerate Breakdown and Carrier Matrix Matching
During twin-screw compounding, organic and inorganic pigments exist as agglomerates (>10 microns). Our high-dispersion technology utilizes hyper-dispersants to lower interfacial energy, breaking agglomerates down to sub-micron primary particles (20–50 nm) under controlled hydro-dynamic shear fields.
Mismatching carrier MFI causes phase separation, pinholes, and reduced tensile yield strength in blown film. We engineer specialized LLDPE/LDPE carrier systems possessing narrow molecular weight distributions (MWD), enabling instant homogenous melt blending with LLDPE, LDPE, and HDPE resins.
Pigment blooming and migration degrade surface printing quality and heat seal strength. By incorporating high-molecular-weight polymeric dispersants and heat-stable pigments rated to 260°C–300°C, our masterbatches prevent dye crystallization and molecular leaching.
| Technical Parameter | Standard PE Masterbatch | Jiazhou High Dispersion Masterbatch | Impact on End Application |
|---|---|---|---|
| Filter Pressure Value (FPV) | 2.5 – 5.0 bar/g | < 0.8 bar/g (DIN EN 13900-5) | Eliminates screen pack clogging; prevents film tearing in thin blown film (<15μm). |
| Pigment Particle Size (D90) | > 5.0 microns | < 0.5 microns | Eliminates specking, fish-eyes, and color streaks; maximizes tinting strength. |
| Thermal Stability Rating | 200°C – 220°C | 260°C – 300°C | Prevents color degradation and gas off-gassing in high-temperature injection molding. |
| Carrier MFI (190°C / 2.16kg) | Unregulated (5 - 15 g/10min) | Engineered (20 - 45 g/10min) | Ensures rapid dispersion during short dwell cycles without compromising physical strength. |
| Color Consistency (CIELAB ΔE) | ΔE > 1.5 | ΔE < 0.5 (Batch-to-Batch) | Guarantees exact color matching across global manufacturing sites. |
Changzhou Jiazhou Plastic Products Co., Ltd.: 16 Years of Advanced Polymer Compounding Expertise
Located in Changzhou, Jiangsu Province, our facility houses high-torque co-rotating twin-screw compounding lines, continuous kneaders, and automated gravimetric dosing systems designed for high-density pigment loading.
Every batch undergoes rigorous spectro-photometric analysis (Datacolor 800), melt index verification, thermo-gravimetric analysis (TGA), and pressure-filter mesh testing to guarantee zero-defect shipment.
Leveraging Changzhou's strategic petrochemical cluster, we source virgin PE carriers and premium pigments at scale, passing down 15–25% cost savings to overseas B2B buyers compared to Western compounders.
Meeting International Environmental and Safety Directives for Food Packaging and Consumer Goods
International plastic converters face stringent regulatory hurdles, particularly when manufacturing items intended for food contact, medical devices, or children's products. At Changzhou Jiazhou Plastic Products Co., Ltd., our masterbatch formulations are engineered to pass the world's most demanding chemical safety standards.
Every raw pigment, organic dye, carrier polymer, and processing aid is thoroughly audited for heavy metals, aromatic amines, and endocrine disruptors before entering our compounding extruders.
Tailored Formulations Optimized for Specific Plastic Processing Machinery and Field Environments
Designed for high-speed multi-layer co-extrusion blown film lines. Our PE masterbatch delivers flawless opacity, streak-free color distribution, and uniform film thickness in shopping bags, agricultural mulch films, and barrier pouches down to 8 microns.
Optimized for fast molding cycles with minimal mold deposit (plate-out). Provides vibrant surface gloss, warp-free dimensional stability, and uniform shrink-rate compensation in consumer electronics, crates, and automotive interiors.
Formulated with premium P-type carbon black and UV absorbers for outdoor water supply pipes, corrugated conduits, and wire jacketing. Delivers superior long-term weatherability, UV resistance (>15 years outdoor lifetime), and hydrostatic strength retention.
Pioneering Circular Economy Solutions, PCR Carrier Integration, and Smart Additive Blends
Driven by global ESG requirements, we have developed high-dispersion masterbatches using up to 100% certified PCR PE carriers. These formulations allow brands to boost PCR content in finished packaging without sacrificing color brilliance or tensile strength.
Traditional carbon black absorbs NIR radiation in automated recycling sorting facilities, causing plastic waste to end up in landfills. Our NIR-detectable black masterbatch enables seamless optical sorting in modern recycling plants.
Integrating primary colorants with anti-static, anti-block, UV-stabilizers, and processing aids into a single masterbatch pellet. This reduces machine dosing complexity, minimizes thermal history, and lowers energy consumption during processing.
