Engineered with high pigment loads and polymer-matched carriers for superior tinting strength, zero migration, and rapid industrial dispersion.
Technical insight into microscopic dispersion physics, rheological optimization, and high-load organic/inorganic colorant matrices.
Modern plastic processing demands absolute compatibility between the carrier resin and the base polyolefin substrate. Polyethylene (PE) pigment compounds engineered at our Changzhou plant utilize virgin LDPE, LLDPE, or HDPE carriers matched precisely to the melt flow index (MFI) of target polymers. This prevents interfacial tension mismatch, pinhole formation in ultra-thin blown films, and physical property degradation during high-speed processing.
Pigment agglomeration leads to streak defects, filter clogging, and mechanical weakness. Utilizing triple-stage co-rotating twin-screw extruders with custom L/D (length-to-diameter) screw profiles, our manufacturing process subjects organic pigments (Phthalocyanines, Quinacridones) and inorganic metal oxides (Titanium Dioxide, Carbon Black) to high shear rates, achieving sub-micron particle dispersion across all color concentrates.
High-temperature processing (up to 260°C–300°C) subjects color compounds to thermal degradation. Our formulated PE pigment compounds incorporate proprietary Hindered Amine Light Stabilizers (HALS) and primary/secondary antioxidant packages (Irganox/Irgafos series), ensuring long-term UV resistance (Light Fastness 7-8 on the Blue Wool Scale) and heat-stable chromatic purity.
Technical Superiority Insight: High-concentration PE masterbatches reduce the total cost-in-use by optimizing pigment tinting strength. A lower let-down ratio (LDR of 1% to 3%) allows plastic converters to minimize shipping weight, reduce storage footprint, and maintain the intrinsic mechanical toughness of virgin PE resins.
