Engineered with high pigment loading, superior matrix dispersion, and optimized thermal-antioxidant synergistic packages for global converters.
Polyethylene (PE), including HDPE, LLDPE, and LDPE resins, is intrinsically vulnerable to thermal and oxidative degradation during thermal melt processing (extrusion, blown film, injection molding) and extended outdoor end-use exposure. Under the synergistic influence of thermal stress, shear forces, and dissolved oxygen, polyolefin polymer chains undergo radical-initiated autoxidation. This chemical breakdown leads to alkyl radical ($\text{R}^\bullet$) generation, hydroperoxide formation ($\text{ROOH}$), chain scission, cross-linking, discoloration (yellowing index elevation), and catastrophic loss of tensile and impact strength.
As a leading China Anti-Oxidation PE Masterbatch Factory & Supplier, Changzhou Jiazhou Plastic Products Co., Ltd. formulates state-of-the-art masterbatch systems utilizing a dual-stage, synergistic stabilization matrix combining Primary Hindered Phenolic Antioxidants and Secondary Organophosphite Hydroperoxide Decomposers integrated into premium linear low-density polyethylene carrier resins.
Sterically hindered phenols act as hydrogen donors to terminate free radical propagation chains. By reacting with peroxyl radicals ($\text{ROO}^\bullet$), they arrest the cascade mechanism before auto-acceleration damages the polymer backbone, preserving the initial Melt Flow Index (MFI) and structural ductility during melt temperatures reaching up to 260°C – 300°C.
Trivalent organophosphite processing stabilizers reduce reactive hydroperoxides ($\text{ROOH}$) into inert alcohol derivatives, simultaneously converting themselves into non-reactive phosphates. This action prevents peroxide-induced cross-linking, eliminating gel formation, fish-eyes, and surface rough spots in high-clarity blown film extrusion.

Tailored thermal-stabilization and masterbatch carrier formulations engineered for harsh ambient conditions and intense mechanical load applications.
Agricultural LDPE/LLDPE mulch and greenhouse films are subject to high thermal radiation and pesticide interaction. Jiazhou Anti-Oxidation Masterbatch acts as a thermal shield, preventing UV-induced thermo-oxidative collapse, extending multi-season greenhouse cover lifespan up to 36 months.
For landfill liners, mining leach pads, and water reservoirs, long-term oxidative resistance (OIT requirement > 100 min) is a mandatory engineering standard. Our proprietary formulation prevents environmental stress cracking (ESCR) under acidic and alkaline soil conditions.
In high-speed production of logistics pallets, chemical drums, and courier packaging, processing temperatures cause thermal discoloration. Jiazhou masterbatches deliver flawless color vibrancy, high impact resistance, and zero pigment migration across high-speed injection lines.
Integrating 16 years of polymer modification expertise with automated high-torque compounding lines to deliver world-class consistency and competitive B2B pricing.
Located in the chemical industrial cluster of Changzhou, Jiangsu Province, Changzhou Jiazhou Plastic Products Co., Ltd. operates multiple high-aspect-ratio twin-screw extruder compounding systems. Our digital loss-in-weight gravimetric feeding technology guarantees that antioxidant active ingredients, organic pigments, and carrier resins are blended with an absolute concentration tolerance of $\le \pm 0.15\%$.
Every production lot undergoes rigorous laboratory verification prior to international dispatch: filter pressure value (FPV) testing to ensure sub-micron dispersion, Differential Scanning Calorimetry (DSC) for Oxidation Induction Time analysis, and high-temperature melt flow verification. This precise control mechanism guarantees seamless performance in client extruders without filter screen clogging or process instability.
Pioneering eco-friendly polyolefin additive technologies to align with global circular economy goals and strict environmental mandates.
Modern automotive interior packaging and food-contact containers demand near-zero volatile organic compound (VOC) emissions. Jiazhou’s high-molecular-weight hindered phenol formulations minimize blooming, fogging, and extraction into food simulants, fully satisfying EU Directive 10/2011 and FDA CFR 178.2010 standards.
In response to carbon neutrality goals, Jiazhou is expanding its sustainable product line by integrating 100% bio-based Polyethylene carriers derived from sugarcane ethanol. These carriers maintain full thermodynamic compatibility with fossil-based LLDPE/HDPE while significantly reducing the product's overall cradle-to-gate carbon footprint.

Equipped with spectrophotometers and custom twin-screw lab units, our R&D engineers match target Pantone/RAL codes and custom antioxidant concentrations within 48 to 72 hours, delivering tailored sampling for factory trials.
Addressing common procurement, technical dosage, and processing queries regarding Anti-Oxidation and Color PE Masterbatches.
The standard recommended let-down ratio (dosage) typically ranges between 1.0% and 3.0% by weight, depending on the recycled resin percentage, processing temperature, and outdoor exposure requirements of the final film. For 100% virgin LLDPE film extruded under 220°C, a 1.0% - 1.5% dosage provides optimal stabilization. For high-percentage PCR (post-consumer recycled) resin compounds, a 2.5% - 3.0% dosage is recommended to restore oxidative thermal stability.
Jiazhou color and antioxidant masterbatches utilize ultra-fine micronized pigment particles co-extruded with high-molecular-weight primary antioxidants and carrier polymers identical to the matrix resin. This chemical structure prevents additive phase separation (blooming) and prevents thermal degradation up to 260°C – 300°C, ensuring no color shift ($\Delta E < 1.0$) or surface migration over time.
Yes. We supply food-contact grade masterbatches formulated strictly in compliance with US FDA 21 CFR 178.2010 and EU Regulation No 10/2011.
