High-concentration, heat-stable, non-migrating color concentrates engineered specifically for polyolefin film, pipe, sheet, and profile extrusion lines.
A comprehensive evaluation of pigment dispersion, carrier rheology, and thermal shear dynamics in industrial plastic processing.
In modern industrial polymer processing, the selection of an optimal Extrusion PE Masterbatch serves as the fundamental pillar for achieving surface homogeneity, mechanical integrity, and vibrant aesthetic consistency in downstream products. Extrusion processes—encompassing blown film, cast film, sheet extrusion, pipe co-extrusion, and cable jacketing—impose intense thermomechanical shear on polymer melt streams. To prevent issues like pigment agglomeration, melt fracture, die build-up, and localized stress concentration, high-grade color and functional additive masterbatches must be engineered with absolute rheological precision.
As a premier 16-year masterbatch manufacturing powerhouse, Changzhou Jiazhou Plastic Products Co., Ltd. synthesizes technical-grade polyethylene (PE) carriers with micronized inorganic pigments, organic colorants, and active chemical additives. By maintaining strict control over Melt Flow Index (MFI) matching, carrier resin compatibility (LDPE, LLDPE, HDPE), and twin-screw dispersive mixing, Jiazhou delivers masterbatch formulations designed to optimize plastic extrusion efficiency worldwide.

Understanding the molecular interaction between virgin resins, recycled substrates, and masterbatch carrier systems.
A fundamental failure in plastic extrusion occurs when masterbatch carrier resin melt viscosity mismatches the base polymer. Jiazhou formulates PE masterbatches using specific low-molecular-weight LLDPE or high-MFI PE bases (MFI ranging from 10 to 45 g/10min), ensuring rapid melt blending without lowering the mechanical tensile strength of the extruded end-product.
Agglomerated pigment particles cause pinholes and streak defects in thin blown films (down to 10 microns). Utilizing specialized hyper-dispersants and Titanate/Silane coupling agents, Jiazhou masterbatches achieve a pigment dispersion particle size below 2.5 microns, yielding brilliant opacity and structural film integrity.
During high-speed profile or pipe extrusion, barrel temperatures routinely spike. Jiazhou's heat-resistant formulations (e.g., Red, Black, and Blue PE Masterbatches) prevent color shifts, sublimation, and chemical breakdown under continuous melt temperatures reaching up to 260°C.
| Property Parameter | Standard Testing Value | Test Methodology | Industrial Impact / Advantage |
|---|---|---|---|
| Carrier Resin Type | PE (LDPE / LLDPE / HDPE Compatible) | ASTM D1238 / ISO 1133 | Ensures seamless polymer cross-linking and non-separation. |
| Pigment Loading Concentration | 30% - 75% High Concentration | Ash Content / TGA Testing | Lower Let-Down Ratio (LDR 1%-4%), reducing overall production costs. |
| Heat Fastness / Thermal Stability | 220°C - 260°C (5 mins holding) | DIN EN 12877-2 | Prevents color degradation during long residence time extrusions. |
| Light Fastness (Blue Wool Scale) | Grade 6 to Grade 8 | ISO 105-B02 (Xenon Arc) | Prevents premature fading in outdoor agricultural films & pipes. |
| Migration Resistance | Grade 5 (Zero Color Bleed) | DIN 54006 | Prevents pigment transfer in food packaging and co-extruded layers. |
| Filter Pressure Value (FPV) | < 0.8 bar/g (Fine Mesh Test) | EN 13900-5 | Eliminates screen pack clogging and extends continuous extruder run times. |
Driving the future of sustainable, smart, and ultra-high-efficiency polyolefin extrusion technology.
With global mandates pressing for circular economy solutions, Jiazhou is pioneering masterbatch carrier technology compatible with 100% Post-Consumer Recycled (PCR) HDPE/LDPE resins. Advanced odor-masking and melt-compatibilizing additive masterbatches assist extruders in turning degraded regrind into high-performance plastic products.
Next-generation Black and White PE masterbatches leverage nano-scale particle surface treatment. This technology delivers UV protection (Cabon Black P-type and N-series) down to 15nm while boosting total opacity and thermal insulation properties in agricultural geomembranes.
Moving beyond basic color, Jiazhou's research laboratory focuses on combo-masterbatches combining colorants with Anti-Static, Anti-Block, PPA (Polymer Processing Aid), and Anti-UV stabilizers into single-pellet solutions, streamlining inventory management for extruders.
Customized Extrusion PE Masterbatch formulations engineered for target industrial sectors.
In 3-layer, 5-layer, and 7-layer blown film extrusion lines, high concentration White (TiO2) and custom color PE masterbatches provide barrier opacity and bright branding hues for milk pouch films, heavy-duty shipping sacks, and courier bags without altering sealability.
For municipal water distribution, gas lines, and telecommunication ducting, Jiazhou's specialized HDPE Black (Carbon Black loading up to 50%) and Blue stripe masterbatches ensure strict UV stabilization, oxidative induction time (OIT), and pressure compliance.
Agricultural films require severe weatherability. Jiazhou's Anti-Fading Silver, Green, and Black PE masterbatches withstand continuous pesticide exposure and intense solar UV degradation in farming regions across the Middle East, Southeast Asia, and South America.
