Runpacet High-Concentration Liquid Color Masterbatch: An Innovative Coloring Solution for the Future
Liquid color masterbatch is a high-concentration pigment/dye coloring additive that uses a liquid dispersant as its carrier. Its unique liquid nature grants it exceptional compatibility with a vast majority of polymer carriers (such as PET, PC, PA, PETG, ABS, PS, PBT, PP, PE, TPU, PLA, etc.), alongside a heat resistance of up to 320°C. This product requires minimal dosage, achieves superior dispersion, and fully preserves the original physical properties of the base material.
For light-colored or transparent plastic products, an addition rate of only 0.05–0.1% effectively solves the common issue of uneven color distribution associated with traditional solid masterbatch, significantly reducing overall coloring costs and inventory requirements. It is equally suitable for semi-opaque and white products, providing excellent coverage and achieving a high-quality, speck- and black-point-free surface.
The product fully complies with international mainstream certification standards such as FDA, REACH, and EU 10/2011, meeting the stringent global market demands for safety and sustainability.
Liquid Color Masterbatch for Premium Packaging
Widely used in high-end packaging such as PET beverage bottles, mineral water bottles, pharmaceutical bottles, and personal care/cosmetic bottles. Compared to traditional solid masterbatch, products using liquid masterbatch exhibit superior gloss, color uniformity, and overall cost-effectiveness.
In one-step injection stretch blow molding processes (e.g., for PETG/PET), liquid masterbatch effectively reduces melt adhesion to the screw, avoids mold cavity bubbles caused by rheological issues, and ensures excellent batch-to-batch color consistency, providing dual assurance for both the visual quality of packaging and production efficiency.
Liquid Colorant for 3D Printing
For materials like PLA, PETG, ABS, PA, TPU, and photosensitive resins, liquid masterbatch acts as a liquid medium that rapidly and uniformly blends with the base material in the screw extruder. Its excellent flowability ensures stable filament diameter and a smooth surface,completely solves problems common with solid masterbatch such as large diameter fluctuations, impurities, and surface roughness, significantly improving print quality and production efficiency.
We provide primary colors (red, yellow, blue, green, black, white) for customers to flexibly create custom color formulations.
Liquid Colorant for Synthetic Fibers
The new generation of liquid color masterbatch for synthetic fibers is specifically designed for pre-spin coloring of fibers like polyester and polypropylene. This technology enables waterless dyeing, providing vibrant, durable, and even coloration. The product is easy to incorporate, and the process is low-carbon and environmentally friendly, aligning with the modern textile industry’s trend towards green transformation and sustainable development.
Automatic Dosing System
We also provide precise and reliable automatic liquid color dosing systems. This system, through the coordinated operation of high-precision metering valves and high-speed pre-mixers, delivers accurate, uniform, and stable coloring solutions for plastic processing.
The metering valves enable precise control of the addition amount, while the pre-mixer ensures instant and thorough integration of the colorant with the raw materials through high-speed agitation, guaranteeing high consistency in color distribution from the source. This system is suitable for various industrial scenarios, including continuous and batch production, and is particularly well-matched for production lines with stringent color consistency requirements, such as those for food, pharmaceutical, and high-end consumer goods packaging.
This integrated solution provides customers with full-process color management support from raw material to finished product, serving as a key technical partner in enhancing product quality stability and production efficiency.
