Engineered specifically for high-durability blown film, injection molded housing units, electrical enclosures, and industrial plastic extrusions requiring precise chromophores and zero pigment migration.
As global OEMs transition toward lighter, more durable, and ecologically compliant polyolefin structures, polyethylenes (HDPE, LLDPE, LDPE) have emerged as essential polymers for protective enclosures, electronic housings, and industrial shells.
In modern polymer processing, direct liquid tinting or raw powder pigment blending introduces batch-to-batch inconsistency, severe dusting contamination, and uneven shear distribution. As a leading China PE plastic housing masterbatch company and supplier, Changzhou Jiazhou Plastic Products Co., Ltd. resolves these processing bottlenecks through state-of-the-art twin-screw co-rotating extrusion compounding.
The global demand for high-performance PE plastic housing color concentrate is driven by three pivotal market forces: structural durability in extreme environments, ultra-precise color matching for brand consistency, and regulatory compliance regarding toxic heavy metals and halogen-free standards. Whether manufacturing large agricultural chemical tanks, electronic outdoor meter boxes, or consumer appliance housings, engineers require masterbatch systems that combine high pigment loading with low rheological drag.
Achieving optimal dispersion within polyolefin housing matrices requires scientific selection of virgin carrier resins matching the Melt Flow Index (MFI) of the host polymer.

| Lightfastness Rating | Grade 7 – 8 (Blue Wool Scale) | ISO 105-B02 Xenon Arc | Guarantees multi-year outdoor UV stability without chalking or yellowing. |
| Migration Resistance | Grade 5 (Zero Bleeding) | DIN 54006 / ISO 105-X12 | Eliminates pigment transfer to touch surfaces or contiguous components. |
| Moisture Content | < 0.15% max | Karl Fischer Titration (ISO 15512) | Prevents splay marks, surface silver streaks, and void formation in molded shells. |
Microscopic particle agglomeration is the primary root cause of structural weakness and aesthetic defects in plastic housings. Jiazhou utilizes continuous multi-stage compounding extruders featuring specialized kneading blocks and shearing elements. By micronizing organic and inorganic pigments down to < 2.5 microns, our PE masterbatches disperse uniformly across high-molecular-weight polyethylene matrices. This eliminates stress concentration points, boosting the impact resistance and tensile yield strength of the finished plastic housing.

The standard let-down ratio typically ranges between 1% and 4% by weight, depending on the pigment concentration of the specific color masterbatch and the required opacity or wall thickness of the plastic housing shell. For high-concentration formulations, a 2% addition rate is usually sufficient to achieve full color saturation and optical hiding power.
Matching the carrier resin to the host polymer (e.g., LLDPE carrier for HDPE or LLDPE base resin) is essential to maintain polymer chain entanglement. Using an incompatible carrier (such as EVA or PP carriers in high-stress PE housings) can cause delamination, surface peeling, reduced environmental stress crack resistance (ESCR), and lowered impact resistance.
Yes. Our color concentrates are engineered with inert, non-reactive pigments that do not interfere with halogenated or halogen-free (ATH, MDH, red phosphorus) flame retardant systems. They maintain the thermal stability and flame retardancy ratings (UL94 V-0, V-1, V-2) of the compound.
All our PE housing masterbatches undergo Thermogravimetric Analysis (TGA) and heat residence testing up to 260°C – 300°C for 10-minute dwell cycles. Pigments are selected to ensure zero color shift (ΔE < 0.5) and no thermal decomposition during processing.
Every shipment is accompanied by a Certificate of Analysis (CoA), SDS (Safety Data Sheet), and third-party laboratory reports verifying compliance with REACH SVHC, RoHS 3, US FDA 21 CFR (where food contact is required), EN71-3, and heavy metal limits (CONEG/94/62/EC).
We select high-molecular-weight organic pigments and inorganic oxides with high solvent resistance (Grade 5). This prevents pigment migration or bleeding into surface coatings, pad printing inks, or secondary adhesive bonding layers on plastic housings.
