Explore our flagship high-concentration color pellets engineered for consistent melt flow index (MFI), high thermal stability (up to 260°C–300°C), and non-migratory pigment performance.
Understanding the critical engineering interface between Polyethylene (PE) carrier resins, organic pigments, inorganic oxides, and target polymer substrates.
The performance of PE carrier color pellets depends heavily on matching the Melt Flow Index (MFI) of the masterbatch carrier to the base polymer resin (HDPE, LLDPE, or LDPE). Our engineering team optimizes melt viscosity between 10 g/10min and 45 g/10min (190°C/2.16kg) to guarantee complete phase integration without shear degradation or melt fracture during high-speed film extrusion.
Poor pigment dispersion results in pinholes, streakiness, and mechanical failure in thin-gauge blown films. By leveraging triple-roll milling and high-shear twin-screw extruders, Changzhou Jiazhou ensures micro-encapsulated pigment particle sizes under 2.5 microns. This guarantees flawless surface aesthetics, maximum tinting strength, and high opacity at minimal Let-Down Ratios (LDR 1%–4%).
Processing temperatures in injection molding and pipe profile extrusion can reach up to 260°C–300°C. Our specialized color pellets utilize thermally stabilized organic pigments (phthalocyanines, quinacridones) and coated rutile Titanium Dioxide ($TiO_2$). This eliminates organic dye migration, gas fading, and thermal discoloration during prolonged hot-runner molding cycles.
Located in Changzhou, Jiangsu, Changzhou Jiazhou Plastic Products Co., Ltd. combines 16+ years of polymer formulation experience with automated digital compounding infrastructure.
Our factory features automated continuous gravimetric feeding systems that monitor raw pigment loading, wax dispersants, and resin carriers in real-time. This eliminates human error during batching, ensuring batch-to-batch color tolerance of $\Delta E \le 0.30$ measured under spectrophotometer (D65 light source). Global buyers obtain identical color reproduction across multi-ton production shipments over multi-year procurement contracts.
Situated in the heart of Yangtze River Delta industrial cluster, Jiazhou benefits from immediate access to primary raw material suppliers ($TiO_2$, Carbon Black N220/N330, PetroChina PE resins) and deep-water shipping lines via Shanghai and Ningbo ports. This cluster synergy allows us to guarantee standard order manufacturing cycles within 7 to 12 working days, safeguarding international OEMs against global supply chain bottlenecks.
Driving sustainable polymer engineering through circular economy masterbatch integration, bio-PE carriers, and advanced functional additivities.
As international regulations enforce Post-Consumer Recycled (PCR) content quotas, standard colorants often fail due to residual polymer degradation. Our R&D team has developed specialized PCR-compatibilized PE color pellets containing reactive antioxidants and chain extenders that neutralize odor, suppress black specks, and restore tensile strength in recycled PE film and bottle compounding.
Transitioning away from fossil-based resins, Jiazhou is expanding its bio-based polyethylene carrier portfolio derived from sugarcane ethanol. Bio-PE color pellets offer identical chemical, physical, and processing parameters to conventional LDPE carriers while dramatically lowering Scope 3 carbon footprints for eco-conscious global consumer brands.
The future of masterbatch compounding lies in multi-attribute single-pellet solutions. We are integrating high-pigment loads with active functional additives—such as Hindered Amine Light Stabilizers (HALS UV protection), permanent anti-static agents, and slip additives (erucamide/oleamide)—eliminating the need for multi-dosing systems on the factory floor.
Empowering global enterprises to pass rigorous international chemical and food-contact safety audits seamlessly.
All Jiazhou PE carrier color pellets undergo strict third-party testing via SGS, Intertek, and TÜV Rheinland. Our core formulations fully satisfy international food contact and chemical toxicity standards:
We do not merely supply pellets—we deliver complete end-to-end processing solutions. Our global technical support initiative offers customized assistance for plastic converters:
