Explore our top-tier custom-formulated color masterbatches, engineered with non-toxic organic/inorganic pigments and premium polyolefin carrier resins.
In modern plastics conversion, moving away from legacy heavy-metal colorants (such as Lead Chromate, Cadmium Sulfide, and Di-arsenic Trioxide) is no longer just a regulatory option—it is a critical commercial necessity for compliance, consumer safety, and brand protection.
Heavy metal elements like Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr VI), Polybrominated Biphenyls (PBB), and Polybrominated Diphenyl Ethers (PBDE) pose severe toxic risks. Our masterbatches utilize pure organic and non-toxic mineral pigment matrices guaranteed to contain total trace heavy metals well under 5 ppm (measured via ICP-OES spectroscopy).
Replacing heavy metal inorganic pigments with high-performance organic pigments historically presented challenges in heat fastness. Changzhou Jiazhou's proprietary dispersion additives stabilize organic chromophores against molecular degradation during high-temperature polyethylene extrusion, blown film, and injection processes.
Improper pigment selection can lead to surface blooming, chalking, or migration into stored liquids or dry goods. Our heavy-metal-free PE masterbatches exhibit high solvent fastness, lightfastness ratings of 7–8 on the Blue Wool Scale, and weather resistance ratings of 4–5 on the Grey Scale.
| Property Parameter | Test Standard / Method | Jiazhou Standard Value | Industrial Advantage |
|---|---|---|---|
| Heavy Metal Content (Pb, Cd, Hg, Cr VI) | ICP-OES / EN 71-3 / RoHS 3.0 | < 2 ppm (Non-Detectable Threshold) | Fully compliant with FDA, EU Food Contact & Toy Safety |
| Heat Fastness Stability | DIN EN 12877-2 | 260°C – 300°C (Dwell time 5 mins) | No color shift or degradation during long extrusion cycles |
| Light Fastness / UV Rating | ISO 105-B02 (Blue Wool Scale) | Grade 7 – 8 | Prevents outdoor fading in agricultural & industrial films |
| Carrier Resin Polymer | ASTM D1238 Melt Flow Index | PE (LDPE / LLDPE / HDPE Carrier) MFI 12-25 g/10min | Flawless rheological compatibility & micro-dispersion |
| Filter Pressure Value (FPV) | EN 13900-5 | < 0.8 bar/g (Mesh size 14 µm) | Prevents screen pack clogging during ultra-thin film blowing |
Our targeted chemical compounding ensures pristine coloring performance across diverse processing technologies and demanding regulatory environments worldwide.
Polyethylene food contact films, milk bags, stretch wrap, and blow-molded condiment bottles require non-migratory color additives compliant with FDA 21 CFR 178.3297 and EU Regulation No 10/2011. Jiazhou's heavy-metal-free masterbatch prevents organoleptic degradation, safeguarding food taste and safety.
Under European Standard EN 71-3 (Safety of Toys - Migration of Certain Elements) and US CPSIA rules, children's toys and feeding utensils undergo intense mastication and chemical leaching tests. Our zero-lead, zero-cadmium formulations guarantee absolute peace of mind for consumer toy brands.
For cleanroom injection-molded IV syringe barrels, pharmaceutical bottle caps, and medical grade LDPE tubing, purity is non-negotiable. Our masterbatches feature high chemical resistance, zero cytotoxic leachables, and full compatibility with Gamma-ray and Ethylene Oxide (EtO) sterilization processes.
Extruded HDPE/LLDPE geomembranes, mulch films, and greenhouse covers operate under harsh UV light and soil pesticide exposure. Heavy metal catalysts can accelerate polymer photo-oxidation. Our heavy-metal-free additives enhance longevity and support sustainable agricultural soil health.
Polyolefin auto trim, wire/cable jacketing, and corrugated pipe profiles demand strict low-VOC and low-fogging characteristics. Our non-toxic PE masterbatches retain physical impact strength and electrical insulation properties while meeting global automotive OEM material standards.
Blow-molded 200L L-Ring HDPE drums and intermediate bulk containers (IBCs) storing hazardous chemicals require heavy-metal-free coloring to prevent catalytic reaction with stored reactive liquids during long-distance maritime transit.
Changzhou Jiazhou Plastic Products Co., Ltd. leverages 16 years of manufacturing precision and Changzhou's world-class chemical cluster infrastructure to deliver unmatched stability, cost-efficiency, and rapid delivery timelines.
Our 6,000m² manufacturing facility operates multiple continuous high-torque twin-screw extruders integrated with multi-component gravimetric feeders, underwater pelletizing, and vacuum degassing units. This setup achieves ultra-high pigment loading (up to 70% concentration) with flawless homogeny, ensuring zero agglomeration during high-speed film extrusion.
Situated in the heart of the Yangtze River Delta industrial belt, Changzhou Jiazhou maintains direct strategic raw material partnerships with top-tier polyolefin producers (Sinopec, CNPC) and international non-toxic pigment leaders. This direct integration shields our overseas clients from global market volatility and guarantees raw material traceability.
Every single batch undergoes rigorous quality assurance before dispatch. Our laboratory is equipped with Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES) for trace heavy metal screening, DataColor 800 spectrophotometers for Delta E color matching (Delta E < 0.5 guaranteed), and automated MFI testers.
With standardized inventory of virgin PE carrier resins and heavy-metal-free pigments, Changzhou Jiazhou turns custom color formulation orders into delivered goods faster than industry benchmarks. Proximity to Shanghai Port and Ningbo Port allows seamless 15-day sea freight dispatch for international B2B buyers.
As global ESG frameworks tighten and circular economy mandates expand, Changzhou Jiazhou is pioneering next-generation polyolefin additives for a cleaner planet.
Transitioning from fossil-fuel low-density polyethylene to Bio-PE carriers derived from sugarcane ethanol. This innovation maintains identical melt rheology and compatibility while significantly reducing the cradle-to-gate carbon footprint of the masterbatch.
In response to global regulations banning Per- and Polyfluoroalkyl Substances (PFAS), Jiazhou is engineering heavy-metal-free, fluorine-free processing aids that eliminate melt fracture (sharkskin) in blown film extrusion without environmental persistence.
Formulating high-tinting-strength masterbatches designed specifically to neutralize odor, yellowing, and optical defects in post-consumer recycled PE streams, enabling plastic convertors to meet 30%+ recycled content targets seamlessly.
