Engineered with high pigment loadings and optimal carrier matrix dispersion for blown film, injection molding, and continuous profile extrusion.
Understanding the physics of pigment wetting, shear-induced de-agglomeration, and carrier matrix compatibility in high-speed thermoplastics processing.
During compounding, the molten carrier polymer must completely wet the surface of primary pigment particles, lowering interfacial tension and replacing air pockets trapped within pigment aggregates.
High shear stress generated by co-rotating twin screws breaks pigment agglomerates down to their fundamental particle size (< 1 micron), eliminating surface streaks and filter clogging.
Dispersing agents and waxes permanently stabilize the de-agglomerated particles, preventing re-coagulation during storage, transport, and final product remelting.

Addressing key technical challenges in polymer coloration, carrier selection, rheology, and global compliance standards.
The carrier resin of a plastic pigment concentrate should ideally match the base processing polymer (e.g., PE carrier for PE resin, PP carrier for PP resin). Mismatched carrier polymers (such as using an EVA carrier in high-density polyethylene) can reduce tensile strength, cause delamination, or lower heat deflection temperature (HDT). When absolute universal compatibility is needed, low-molecular weight specialized copolymers with adjusted Melt Flow Index (MFI) are utilized to preserve impact resistance.
Color streaking occurs due to incomplete dispersion of pigment agglomerates or significant melt viscosity differences between the masterbatch carrier and the virgin resin. To resolve this, we adjust the Melt Flow Index (MFI) of our pigment concentrate to be slightly higher (more fluid) than the base resin, increase twin-screw shear parameters during compounding, and incorporate specialized internal lubricants.
Filter Pressure Value (measured in bar/g per EN 13900-5) quantifies the dispersion quality of a masterbatch by measuring the pressure build-up when molten polymer passes through a fine mesh screen pack. A low FPV (< 0.2 bar/g) indicates minimal un-dispersed pigment agglomerates, making the masterbatch suitable for ultra-thin blown films (down to 8 microns) and fiber spinning without risking film breakage or screen clogging.
Inorganic pigments (such as Titanium Dioxide, Iron Oxides, Cobalt Blue) feature superior thermal stability (exceeding 300°C), exceptional weather resistance (light fastness rating 7-8), and high opacity, but lower color brightness. Organic pigments (such as Phthalocyanines and Azo pigments) provide vibrant color intensity and high tinting strength, but require specialized heat stabilizers to withstand thermal processing above 260°C.
Thanks to high pigment concentration loading (up to 75%), our masterbatches operate efficiently at let-down ratios (LDR) between 1% and 4% (1:100 to 4:100 mixing ratios) depending on wall thickness, opacity demands, and part geometry. Lower LDRs significantly reduce operating costs and storage requirements.
