Engineered for extreme outdoor weatherability, non-migration properties, high thermal resistance (up to 260°C), and optimal melt processing stability across blown film, extrusion, and injection molding applications.
Established in 2010 in Changzhou, Jiangsu Province, Changzhou Jiazhou Plastic Products Co., Ltd. operates a 6,000 m² state-of-the-art compounding facility engineered for international B2B requirements.
Polyolefin resins (LDPE, LLDPE, HDPE) exposed to outdoor solar radiation undergo photo-oxidative degradation triggered primarily by UV-A (315–400 nm) and UV-B (280–315 nm) wavelengths. UV photons break carbon-carbon (C-C) and carbon-hydrogen (C-H) bonds within the polymer backbone, spawning free radicals that initiate Norrish Type I and Norrish Type II chemical reaction cascades. Without advanced chemical stabilization, this process yields macro-molecular chain scission, micro-cracking, loss of tensile elongation, chalking, and catastrophic structural failure. High-Quality Anti-UV Black PE Masterbatch serves a dual functional role: providing jet-black pigmentation while acting as a total broadband UV barrier and radical scavenger system.
How advanced carbon black nano-dispersion combined with Hindered Amine Light Stabilizers (HALS) redefines long-term plastic durability.
Our specialized Anti-UV Black PE Masterbatch incorporates furnace carbon black with primary particle sizes under 20 nanometers and surface areas exceeding 200 m²/g. Particle size directly dictates UV absorption performance: smaller primary particles deliver higher UV extinction coefficients, preventing radiation from penetrating beyond the skin layer of the extruded or molded polyolefin matrix.
Carbon black physically absorbs and reflects light, while high-molecular-weight Hindered Amine Light Stabilizers (HALS) act chemically via the Denisov Cycle. HALS neutralize alkyl and peroxy radicals formed during thermal-oxidative degradation, regenerating active nitroxyl radicals to continuously protect the polymer matrix over decades of outdoor exposure.
Jiazhou Plastic is actively engineering next-generation bio-PE and post-consumer recycled HDPE (PCR-HDPE) carrier systems. Additionally, our R&D roadmap focuses on Near-Infrared (NIR) reflecting black formulations that minimize solar heat absorption in outdoor plastic infrastructure, drastically reducing surface thermal expansion stress.

Tailored masterbatch formulations solving severe weatherability challenges across critical global industries.
Water and gas distribution pipes (ISO 4427 / EN 12201 standards) mandate strict 2.0% to 2.5% carbon black loading to withstand outdoor storage prior to burial. Jiazhou's Anti-UV Black Masterbatch provides exceptional Environmental Stress Crack Resistance (ESCR) retention and micro-dispersion free of agglomerates, preventing structural notch sensitivity under hydraulic pressure.
Agricultural films in tropical and arid regions endure UV radiation intensity exceeding 160–200 kLy/year alongside exposure to acidic agrochemicals. Our specialized masterbatches contain pesticide-resistant HALS packages that do not deactivate when exposed to sulfur or halogenated sprays, ensuring film integrity for multi-season use.
Civil engineering containment membranes require a 50+ year service life under combined exposure to UV radiation, elevated ground temperatures, and leachate chemicals. Jiazhou's high-purity masterbatch meets GRI-GM13 specifications for High-Density Polyethylene geomembranes, maintaining high Oxidative Induction Time (OIT) values.
Outdoor telecommunications and high-voltage power cable outer sheaths are exposed to severe atmospheric elements and thermal cycling. Our masterbatch provides electrical insulation stability, zero dielectric interference, and superior weather resistance for aerial and exposed cable jackets.
From automotive trim and mudguards to heavy-duty plastic pallets, waste containers, and stadium seating. Our Anti-UV masterbatch prevents surface chalking, color fading, and loss of impact toughness under harsh environmental conditions.
Woven polypropylene (PP) and polyethylene (PE) bags and Flexible Intermediate Bulk Containers (FIBCs) require protection against solar degradation during extended port transit and open-air storage. Jiazhou masterbatches maintain tape tensile strength without causing die buildup during high-speed extrusion tape drawing.
Combining automated continuous twin-screw extrusion, gravimetric dosing accuracy, and strategic East China port access for global B2B procurement security.
Precision compounding begins with exact raw material ratio control. Our production lines feature multi-component gravimetric feeders with accuracy within ±0.2%. This eliminates batch-to-batch variation in carbon black and UV additive loading, guaranteeing consistent melt index and let-down performance for our global clients.
Dispersion quality dictates performance. Jiazhou utilizes modular high-torque co-rotating twin-screw extruders engineered with optimized L/D ratios (up to 48:1). Specialized screw element configurations apply intense shear forces to fully break down carbon black agglomerates, ensuring uniform nanoscale dispersion without thermal degradation of the virgin PE carrier resin.
To protect client extruders from nozzle clogging and film breakages, our melt pumps force polymer melt through high-mesh continuous screen changers (100–200 mesh). Finished masterbatch pellets undergo optical sorting and sieving to eliminate oversized particles, dust, or misshapen granules.
Located in Changzhou, within the Yangtze River Delta industrial belt, Jiazhou Plastic benefits from direct highway and rail connections to Shanghai Port and Ningbo-Zhoushan Port—two of the world's largest container shipping terminals. This strategic positioning enables us to guarantee 15-day standard lead times from order confirmation to sea freight departure, providing unprecedented supply chain security against global logistical disruptions.
How high active additive concentrations lower freight expenses, optimize storage space, and reduce overall unit manufacturing costs for global OEM buyers.
Standard market black masterbatches often rely on 20–30% carbon black concentrations, requiring plastic converters to introduce let-down ratios of 6% to 8%. Jiazhou's high-concentration Anti-UV PE masterbatch elevates carbon black loading up to 40-50% with optimized viscosity. This allows customers to lower LDR down to 2% - 3%, reducing overall consumption by up to 40% while preserving mechanical resin properties.
Solar radiation varies significantly by geography—from 80 kLy/year in Northern Europe to over 220 kLy/year in Arizona or the Middle East. Our engineering team customizes UV stabilizer dosages according to target geographical radiation maps and required product lifespan (1 to 25 years), ensuring buyers pay only for the exact thermal and UV protection performance required.

Deep technical answers addressing formulation, processing, testing standards, and order logistics for polymer procurement teams.
According to international standards such as ISO 4427 and ASTM D3350, a final carbon black concentration of 2.0% to 2.5% (by weight) in the finished polymer product is mandatory for long-term outdoor weatherability. When using Jiazhou's 50% high-concentration Anti-UV Black PE Masterbatch, an addition rate (Let-Down Ratio) of 4.0% to 5.0% fully satisfies this requirement, achieving over 3,000 hours of accelerated QUV testing with >85% retention of mechanical tensile strength.
Poor carbon black dispersion results in agglomerates (clumps of undispersed particles). In thin blown films (under 50 microns), agglomerates create pinholes, micro-tears, and structural failure during film blowing. In HDPE pressure pipes, agglomerates act as stress concentration notches under hydraulic pressure, accelerating environmental stress cracking (ESCR). Jiazhou masterbatches achieve a dispersion rating of Grade ≤ 1.5 per ISO 18553, eliminating agglomerate failure.
The carrier resin of the masterbatch must possess a higher melt flow index (MFI) and compatible chemical structure relative to the base polymer matrix. For instance, using an LLDPE carrier ensures seamless blending into LDPE, LLDPE, and HDPE resins without phase separation or optical hazing. Jiazhou offers tailored carrier options including LDPE, LLDPE, HDPE, PP, and universal processing carriers.
Our standard MOQ for stock formulations is 1,000 kg (1 metric ton). For custom color-matched or tailored UV additive masterbatches, the MOQ is 2,000 kg. Thanks to our 6,000 m² factory capacity and twin-screw extrusion output, our standard production lead time is 10 to 15 calendar days from sample sign-off.
Certain halogenated or sulfur-based pesticides used in greenhouses generate acidic byproducts that can deactivate basic HALS compounds. To counter this, Jiazhou formulates specialized agricultural-grade Anti-UV Masterbatches using NOR-HALS (non-basic Hindered Amine Light Stabilizers) which remain chemically active even in high-acid or pesticide-rich environments.
