Precision-formulated color and black masterbatches engineered for maximum tinting strength, superior thermal stability, and uniform micro-dispersion.
Changzhou Jiazhou Plastic Products Co., Ltd. combines 16 years of polymer compounding mastery with global industrial reach.
In modern industrial polymer processing, the performance of black Polyethylene (PE) masterbatch is governed by the physical chemistry of pigment-grade carbon black and its micro-dispersion kinetics within the virgin polyethylene carrier resin matrix. As a premier high carbon black high dispersion black PE masterbatch company and manufacturer, Changzhou Jiazhou Plastic Products Co., Ltd. bridges the gap between raw pigment metallurgy and high-speed plastics conversion.
Carbon black pigment particles naturally exist as primary spherical nodules ranging from 10 to 25 nanometers. However, due to strong van der Waals forces and high surface energy, these primary particles instantly coalesce into primary aggregates and dense secondary agglomerates. If unseparated during twin-screw compounding, these agglomerates manifest as surface pinholes, structural micro-cracks, screen-pack blinding, and optical dullness in downstream plastic extrusions.
To achieve uniform dispersion, our manufacturing lines employ co-rotating twin-screw extruders featuring specialized kneading block configurations. The process relies on three distinct rheological phases:
| Technical Parameter | Standard Grade Masterbatch | Jiazhou High Dispersion Black PE Masterbatch | Industrial Impact / Advantage |
|---|---|---|---|
| Carbon Black Content (%) | 30% - 40% | 40% - 55% High Concentration | Lower let-down ratio required; reduced storage & freight cost |
| Filter Pressure Value (FPV) | > 5.0 bar/g (EN 13900-5) | ≤ 0.8 - 1.5 bar/g | Zero screen pack clogging; suitable for ultra-thin films (< 10 µm) |
| Primary Particle Size | 35 nm - 50 nm | 15 nm - 22 nm High Jetness Grade | Deeper jetness (L* < 4.5), superior UV absorbance up to 400nm |
| Melt Flow Index (MFI 190°C/2.16kg) | Unstable (1 - 5 g/10min) | Tailored (8 - 25 g/10min) | Perfect flow compatibility with HDPE, LLDPE, PP resin bases |
Formulated to excel under extreme mechanical stress, harsh weather conditions, and high-speed processing lines.
Geomembranes require long-term UV protection against solar degradation. Our high dispersion black masterbatch incorporates fine-particle carbon black with high-performance Hindered Amine Light Stabilizers (HALS), ensuring outdoor weathering lifespans exceeding 10 to 25 years without embrittlement.
Underground water and gas distribution pipes demand flawless carbon black dispersion to prevent notch propagation under hydraulic pressure. Jiazhou black PE masterbatch delivers dispersion ratings of Grade 1 (microscope rating), exceeding strict PE100 pipe standards.
Designed for express courier bags, agricultural mulch films, and trash liners down to 8-12 microns thickness. Superior filterability prevents film bubble breakage and surface gel defects, maximizing high-speed extruder throughput.
Provides high surface luster, deep jetness, and zero surface migration. Formulated to resist high ambient processing temperatures (up to 260°C - 280°C) without thermal discoloration or odor emission, matching automotive interior specifications.
As international environmental legislation tightens across North America, Europe, and the Asia-Pacific region, plastic manufacturers face strict compliance hurdles regarding chemical migration, heavy metals, and carbon footprint accountability.
Changzhou Jiazhou Plastic Products Co., Ltd. upholds rigorous raw material screening. Every batch of high carbon black high dispersion black PE masterbatch is subjected to third-party testing to guarantee adherence to international standards:
Recognizing that plastic processing machinery, ambient humidity, and polymer melt flow index vary significantly across global regions, Jiazhou provides comprehensive technical assistance for international OEM partners:
Pioneering sustainable carbon black technologies, bio-carrier integration, and smart inline dispersion monitoring.
To promote circular economy initiatives, Jiazhou is engineering hybrid black masterbatch formulations utilizing pyrolyzed Recovered Carbon Black (rCB). This cuts net carbon emissions by up to 60% while maintaining target jetness and tensile strength.
Developing specialized Electrostatic Discharge (ESD) masterbatches utilizing Highly Conductive Carbon Black (BET > 800 m²/g) to achieve surface resistivity of 10⁴ - 10⁶ ohms/sq for electronics packaging and explosive chemical conduits.
Traditional carbon black absorbs Near-Infrared (NIR) spectrum rays, preventing automated sorting at recycling plants. Jiazhou's NIR-detectable black masterbatch solutions enable optical sensors to identify and sort post-consumer PE packaging effortlessly.
Technical insights addressing key purchasing, engineering, and quality verification queries.
Standard black masterbatches often use larger primary carbon black particles (35-50nm) and lower quality carrier resins, leading to poor dispersion, screen clogging, and reduced mechanical strength. Jiazhou's high dispersion masterbatch utilizes fine-particle carbon black (15-22nm) processed through high-shear twin-screw extruders with specialized dispersion additives. This achieves a Filter Pressure Value (FPV) ≤ 1.5 bar/g, deep jetness (L* < 4.5), exceptional UV protection, and zero impact on the mechanical properties of your finished plastic products.
The carrier resin of the masterbatch must be rheologically compatible with your base resin. For instance, using an LDPE-based masterbatch in an HDPE pipe extrusion line can lower structural stiffness and melt strength. Jiazhou offers custom-matched carrier matrices (LLDPE, LDPE, HDPE, PP, Universal carriers) that ensure seamless melting, identical MFI, and homogenous distribution without causing structural delamination.
Due to our high carbon black concentration (up to 40% - 50%), the standard recommended addition rate ranges from 1% to 4% depending on application requirements:
• Blown Film / Bags: 1% – 2%
• Injection Molding: 2% – 3%
• UV Protective Geomembranes & Outdoor Pipes: 3% – 5% (to achieve > 2.5% net carbon black content in accordance with ISO standards).
Our 6,000m² manufacturing plant operates under ISO 9001:2015 control protocols. Every raw material batch is pre-tested for BET surface area and moisture content. During production, continuous loss-in-weight feeders strictly maintain dosing ratios. Finished pellets undergo laboratory verification via Filter Pressure Value (FPV) testing (EN 13900-5), spectrophotometric colorimetry, and Melt Flow Index (MFI) analysis before release.
Yes. Our high concentration black, white, and color masterbatches are thermally stabilized to endure processing temperatures up to 260°C – 280°C without pigment degradation, gas formation, or odor emission, making them ideal for high-speed injection molding and cast film lines.
From deep black masterbatches to vibrant color and high-opacity white solutions, Jiazhou provides total polymer coloration power.
