High-concentration pigment and functional masterbatches engineered for extrusion, blown film, and injection molding.
Polyethylene polymers exposed to outdoor terrestrial solar radiation suffer photo-oxidative degradation. Formulating high-performance Anti-UV Black PE Masterbatch requires precise control over carbon black morphology and free radical scavenging chemistry.
Solar UV radiation (specifically UV-A 315-400nm and UV-B 280-315nm) excites hydroperoxide impurities in the polyethylene matrix. This triggers homolytic Norrish Type I and II chain scissions, leading to loss of tensile strength, surface embrittlement, and catastrophic micro-cracking.
Carbon black functions as an exceptionally effective UV absorber and physical light screen. Particles with a primary diameter of less than 20 nanometers absorb and dissipate harmful UV wavelengths into harmless thermal energy before photons can react with polymer chains.
While carbon black provides physical screening, incorporating Hindered Amine Light Stabilizers (HALS) provides chemical protection. HALS molecules regenerate through the Denisov Cycle, continuously trapping alkyl and peroxyl radicals over extended service lifetimes.
Standard commercial black masterbatches use coarse carbon black (40-60nm), suitable only for basic coloration. For specialized anti-UV black PE masterbatch intended for 5 to 25-year outdoor exposure (such as HDPE pressure pipes and agricultural geomembranes), premium P-type carbon black with primary particle size ≤20nm and jetness rating >110 is mandatory to ensure uniform spatial distribution and complete UV absorption.
Every batch of Changzhou Jiazhou Anti-UV Black PE Masterbatch undergoes stringent rheological, spectrophotometric, and thermal oxidative induction testing to ensure peak performance in severe outdoor environments.

| Dispersion Quality Level | ISO 18553 / Microtome Test | Rating ≤ 2.0 (Category A) | Eliminates agglomerates, preventing pinholes in blown film. |
| Oxidative Induction Time (OIT) | ASTM D3895 (200°C, O2 flow) | ≥ 100 Minutes | Guarantees long-term thermo-oxidative shelf life under intense sunlight. |
| Moisture Content | Karl Fischer Titration | < 0.05% (500 ppm) | Prevents bubbling, voids, and surface streaking during extrusion. |
| Carrier Resin Compatibility | FTIR Polymer Identification | Virgin LLDPE / HDPE / Polyolefin | Seamless molecular bonding with zero phase separation. |
Anti-UV Black PE Masterbatch is tailored to withstand extreme climate conditions across global market sectors—from high-ultraviolet desert solar farms to sub-zero arctic mining operations.
Deployed in high-UV agricultural regions like the Middle East, Australia, and Southern Europe. Prevents degradation of thin-walled drip irrigation lines subjected to pesticides, fertilizers, and direct sunlight exposure up to 100 kLy/year.
Engineered for heavy-duty 1.0mm to 3.0mm HDPE smooth and textured geomembranes used in tailing ponds, heap leach mining in South America, and municipal landfill containment systems.
Used in telecom fiber optic microducts and high-density outer jacket extrusions for overhead power transmission lines. Guarantees 25+ years of maintenance-free weatherability.
As a 16-year specialized B2B manufacturer in Changzhou, Jiangsu, Changzhou Jiazhou Plastic Products Co., Ltd. combines raw material integration with precision extrusion to supply global polymer buyers.
Located in the heart of China’s Yangtze River Delta plastics industrial cluster, Jiazhou maintains long-term strategic contracts with major petrochemical giants (Sinopec, PetroChina, Sabic). This provides direct access to prime LLDPE and HDPE carrier resins with consistent melt indexes and zero batch-to-batch variation, even during global supply chain disruptions.
Our 6,000m² manufacturing plant operates 8 high-speed co-rotating twin-screw compounding lines fitted with loss-in-weight gravimetric feeders. This ensures micro-dosing accuracy of carbon black and HALS additives within ±0.2%, eliminating color streak issues and guaranteeing uniform physical properties.
Anticipating regulatory tightening and decarbonization mandates, Changzhou Jiazhou is advancing next-generation functional masterbatch technology for sustainable polymer processing.
Developing masterbatches designed for Post-Consumer Recycled (PCR) polyolefin blends. Formulated with specialized compatibilizers and reactive antioxidants to restore thermal stability and color uniformity to degraded PCR resins.
In alignment with EU REACH Annex XVII restrictions and US state PFAS bans, our future-ready masterbatches eliminate fluoroelastomer polymer processing aids (PPA), replacing them with bio-based high-efficiency slip and anti-block modifiers.
Transitioning standard fossil-fuel carrier resins toward sugarcane-derived Bio-PE carriers. Reduces the net product carbon footprint (PCF) by up to 35% without compromising mechanical strength or UV absorption capability.
