As global environmental directives evolve, industrial plastic processors require absolute chemical transparency. Our PE masterbatch formulations are engineered to meet strict international standards, guaranteeing non-toxicity, zero heavy metal migration, and full compliance with European Directive 2015/863 (RoHS 3).
RoHS 3 mandates strict concentration limits on ten hazardous substances in electrical and electronic equipment (EEE) and associated plastic housings. Our polymer matrix formulation utilizes high-purity inorganic pigments and non-di-phthalate organic colorants, eliminating Lead (Pb), Cadmium (Cd), Mercury (Hg), Hexavalent Chromium (Cr6+), Polybrominated Biphenyls (PBB), Polybrominated Diphenyl Ethers (PBDE), and phthalates (DEHP, BBP, DBP, DIBP).
Polyethylene (PE) masterbatches depend heavily on precise Melt Flow Index (MFI) matching between the carrier resin and the virgin polymer matrix (LDPE, LLDPE, HDPE). Our technical formulations utilize low-density polyethylene carrier bases with optimized MFI values ranging from 4 to 20 g/10min (190°C/2.16kg), facilitating instant melt blending, zero screw slippage, and uniform pigment wetting without compromising downstream tensile strength.

|---|---|---|---|---|
| Cadmium (Cd) & Compounds | 100 ppm (0.01%) | < 5 ppm (ND) | ICP-OES / EN 1122:2001 | PASS / CERTIFIED |
| Lead (Pb) & Compounds | 1000 ppm (0.1%) | < 10 ppm (ND) | ICP-OES / EPA 3052 | PASS / CERTIFIED |
| Mercury (Hg) & Compounds | 1000 ppm (0.1%) | < 5 ppm (ND) | ICP-OES / US EPA 3052 | PASS / CERTIFIED |
| Hexavalent Chromium (Cr VI) | 1000 ppm (0.1%) | < 10 ppm (ND) | UV-Vis Spectrophotometry | PASS / CERTIFIED |
| Phthalates (DEHP, BBP, DBP, DIBP) | 1000 ppm total | < 50 ppm (Non-Detect) | GC-MS / EN 14372 | PASS / CERTIFIED |
The quality of a masterbatch is defined by its dispersion quality at the sub-micron scale. Agglomerated pigment particles cause micro-voids, film tears, color streakiness, and nozzle clogging during extruding and injection molding processes.
Our processing plant employs co-rotating twin-screw extruders featuring high length-to-diameter (L/D) ratios of 44:1 to 48:1. Multi-stage kneading blocks deliver controlled mechanical shear, de-agglomerating raw organic and inorganic pigments into uniform sub-micron distributions (<0.5 microns) for optimal color yield.
To ensure zero screen pack clogging in high-speed thin-film extrusion lines (under 15 microns), every production batch undergoes strict Filter Pressure Value testing (EN 13900-5). Our masterbatch products maintain an FPV under 1.2 bar/g, securing continuous extrusion throughput without web breakage.
High-temperature injection molding and sheet extrusion can cause organic colorants to break down, resulting in hue shift or gaseous voiding. By encapsulating thermal-grade pigments within low-volatility antioxidant wax systems, our PE masterbatches resist thermal degradation up to 260°C.
Because our PE masterbatches feature pigment loading levels ranging from 25% up to 70% (depending on color type and carbon black or titanium dioxide concentration), converter plants can operate at economical Let-Down Ratios (LDR) of 1% to 4%. This high yield significantly reduces per-ton raw material input costs while ensuring consistent opacity and tinting strength.
From critical food contact films in North America to heavy-duty agricultural irrigation networks in South America and high-precision electronics housings in Europe, our RoHS compliant PE masterbatch delivers tailored performance across global markets.
Under-the-hood cable conduits, dashboard sub-assemblies, and exterior trim components require low-fogging, heat-stabilized, and UV-resistant polyolefin formulations. Our RoHS-certified Black and Grey PE Masterbatches incorporate high-purity P-type Carbon Black, offering superior weatherability (ISO 4892-2) without off-gassing volatile organic compounds (VOCs).
Compliant with FDA 21 CFR 177.1520 and EU No 10/2011, our Custom PE White and Color Masterbatches are engineered for co-extruded food barrier films, liquid packaging pouches, and container closures. They undergo heavy metal extraction screening to eliminate taste or odor contamination while delivering complete opacity.
Medical specimen bags, pharmaceutical bottle caps, and single-use hygienic tools demand strict cleanroom manufacturing conditions and non-migratory colorants. Our non-toxic PE Yellow, Blue, and White masterbatches prevent pigment leaching when exposed to gamma-ray or ethylene oxide (EtO) sterilization processes.
RoHS 3 directive enforcement is critical in electronic enclosures, power tool bodies, and home appliance casings. Our silver, metallic, and solid color masterbatches guarantee zero electrical conductivity interference, supporting UL94 flammability ratings and eliminating heavy metal traces in compliance with global electronic waste standards.
HDPE water supply pipes, agricultural drip lines, and landfill geomembranes are exposed to aggressive outdoor conditions, UV radiation, and soil chemistry. Our PE Masterbatch series includes Hindered Amine Light Stabilizer (HALS) synergists that extend plastic lifespan to over 20 years in outdoor installations.
Large chemical drums and IBC containers molded from high-molecular-weight HDPE (HMW-HDPE) require strong environmental stress crack resistance (ESCR). Our masterbatches use specialized low-viscosity carrier resins that distribute pigment uniformly without degrading the structural toughness of the container walls.
Situated in Changzhou, Jiangsu Province—the heart of China's polymer processing and chemical engineering cluster—Changzhou Jiazhou Plastic Products Co., Ltd. delivers robust supply chain resilience, raw material cost stability, and fast turnaround for international B2B buyers.
Our strategic location in the Yangtze River Delta provides direct, low-friction access to top-tier virgin resin producers (Sinopec, PetroChina) and pigment manufacturers. By leveraging centralized raw material procurement and long-term volume contracts, we buffer against resin price volatility, passing significant cost savings directly to global customers.
Our 6,000m² facility features continuous gravimetric loss-in-weight dosing systems connected directly to automated twin-screw extrusion lines. This automated feeding architecture eliminates human error during batch mixing, guaranteeing that pigment loading levels, antioxidant additives, and processing aids remain consistent within ±0.1% tolerance.

As global markets transition toward circular economy models and stricter VOC standards, our R&D roadmap focuses on emerging technologies designed to enhance sustainability without sacrificing physical performance.
Recycled polyethylene resins often suffer from melt instability, residual impurities, and inconsistent base colors. We are pioneering specialized functionalized masterbatches containing maleic anhydride grafted PE (PE-g-MAH) compatibilizers. These additives restore tensile strength and bind pigments cleanly within PCR polymer matrices.
Standard carbon black masterbatches absorb NIR radiation, preventing automated optical sorting systems at recycling facilities from identifying polyolefin containers. Our next-generation RoHS compliant NIR-reflecting black formulations enable automated sorting equipment to detect and recycle black PE packaging.
In response to global decarbonization mandates, our material scientists are developing masterbatch carrier platforms based on sugarcane-derived bio-PE resins. Combined with zero-VOC synthetic waxes, these bio-masterbatches lower carbon footprints while maintaining full compliance with strict indoor air quality regulations.
Navigating international customs and strict regulatory audits requires comprehensive technical documentation. We support our global client base with batch-specific Certificates of Analysis (CoA) and verified laboratory testing.
Every masterbatch shipment exported by Jiazhou Plastic includes a complete compliance dossier. This includes updated SGS/TÜV RoHS 3 test reports, REACH SVHC declarations, FDA food-contact safety sheets, and detailed Material Safety Data Sheets (MSDS/SDS) in accordance with GHS standards.
Whether your processing plant requires color matching to Pantone, RAL, or physical target plaques, our laboratory utilizes X-Rite spectrophotometers for accurate color replication within 24 hours. Furthermore, our technical engineers provide remote or on-site troubleshooting for let-down optimization, screw design adjustments, and surface defect elimination.
