Explore our premium range of engineered carrier color concentrates designed for blown film extrusion, injection molding, and industrial plastic profiles.
A comprehensive technical analysis on pigment dispersion, melt flow index matching, anti-migration additives, and thermal stability in polyolefin processing.
In the global thermoplastics industry, sourcing a reliable Custom Grey PE Masterbatch Supplier & Manufacturer involves navigating critical parameters beyond basic color matching. Industrial buyers, polymer engineers, and extrusion specialists seek precision color consistency, tight Delta E control (ΔE < 0.5), superior dispersion without agglomeration, and complete non-migration performance under processing temperatures exceeding 260°C.
As a leading Chinese masterbatch manufacturer—Changzhou Jiazhou Plastic Products Co., Ltd. (operating with 16+ years of dedicated technical experience)—we engineer tailored polyethylene grey masterbatches. Our formulations combine virgin low-density polyethylene (LDPE) or linear low-density polyethylene (LLDPE) carrier resins with ultra-fine inorganic Rutile Titanium Dioxide (TiO₂), Carbon Black (Channel/Furnace process), and specialized organic tinting pigments.
How Changzhou Jiazhou Plastic Products Co., Ltd. leverages state-of-the-art twin-screw extrusion technology and localized raw material ecosystems to deliver high-performance masterbatch worldwide.
Located in Changzhou, Jiangsu Province, our modern 6,000 square meter factory operates multiple co-rotating twin-screw extrusion lines equipped with automatic gravimetric dosing systems to guarantee micro-level batch uniformity.
With established export routes to over 100 countries across Europe, North America, Southeast Asia, and the Middle East, our optimized supply chain ensures rapid order processing and reliable sea/air freight shipping.
We tailor the carrier matrix (PE, PP, EVA, PS) to match your end-use base resin seamlessly, preventing melt flow distortion, phase separation, or tensile strength reduction in extruded films and molded parts.
Direct raw material sourcing from primary petrochemical suppliers combined with high-volume automated pelletization allows us to offer competitive factory-direct pricing without compromising technical quality.
Every lot undergoes rigorous testing, including Melt Flow Index (MFI) analysis, Filter Pressure Value (FPV) testing for dispersion quality, spectrophotometric color analysis, and thermogravimetric testing (TGA).
Standardized chemical and physical properties engineered for seamless integration into high-speed polyolefin converter lines.

Modern global enterprise buyers demand strict adherence to international environmental and safety regulations. Changzhou Jiazhou Plastic Products Co., Ltd. ensures every batch of custom grey masterbatch complies with modern sustainability directives:
Procuring masterbatch from an overseas supplier requires robust localized technical support and flexible commercial terms. We bridge international trade gaps through direct engineering consultation and flexible supply options:
From fine blown film layers to heavy-duty injection molded parts, our custom grey PE masterbatches are tailored for multi-industry versatility.
Ideal for co-extruded multi-layer films, courier express bags, agricultural mulch films, and industrial shrink wraps requiring uniform opacity, streak-free surface finishes, and high pinhole resistance.
Delivers high aesthetic grey finishes for household storage bins, automotive interior trim components, electronic housings, and appliance covers with minimal shrinkage impact.
Engineered for corrugated HDPE electrical conduits, drainage pipes, and structural plastic sheets where long-term UV resistance, thermal stability, and mechanical toughness are required.
Pioneering eco-friendly formulations, NIR-detectable pigments for plastic sorting, and recycled resin compatibility.
Traditional black and dark grey masterbatches formulated with standard carbon black absorb Near-Infrared (NIR) light, making them unidentifiable by automated optical sorting systems in recycling plants. To solve this circular economy bottleneck, Changzhou Jiazhou has developed NIR-Detectable Grey Masterbatch using specialized non-absorbing organic and inorganic pigment blends.
This innovation allows post-consumer PE packaging films and containers to be seamlessly recognized, sorted, and recycled into high-value post-consumer recycled (PCR) resin streams.
With global legislation pushing for higher percentages of recycled plastic in packaging, masterbatches must perform in degraded resin matrices. Our custom grey formulations integrate processing antioxidants and thermal stabilizers that inhibit polymer chain scission during re-extrusion.
This allows plastic converters to maintain mechanical properties while utilizing up to 50%-80% PCR content in their finished products.
