Colorants

We offer a range of colorants optimized for various applications and resin types, based on our long-established dispersion and color-matching technologies. In addition to the products below, we also provide color-matching services for various resins and offer customized products tailored to meet specific needs.

For Polyvinyl Chloride (PVC)

Product name	Form	Features and applications
NSB Base Color	Granule	Colorant for polyvinyl chloride (PVC). Available in various colors. Excellent dispersion, diffusion, and color stability for both soft and hard PVC.
Mini Pellet Masterbatch	Pellet	A color masterbatch with superior diffusion compared to standard-sized pellets. It is excellent for automatic weighing and simplifies the mixing process.
COOL BLACK (Functional Processing Pigment)	Granule	A black colorant that does not use carbon black, making it less likely to absorb infrared radiation. Provides similar coloring power to conventional carbon black colorants, while offering heat prevention effects to molded products, reducing temperature rise under sunlight.

For Polyolefin and Polystyrene

Product name	Form	Features and applications
DEEP BLACK (for Polypropylene)	Pellet	Provides high design quality by highly dispersing difficult-to-process fine carbon black particles into polypropylene (PP) resin, offering superior aesthetics compared to conventional carbon black colorants.
Aluminum Masterbatch	Pellet	Imparts a high-brightness metallic appearance to product surfaces without coarse particles. Contributes to VOC reduction by replacing aluminum coatings with paint-free solutions. Suitable for use in PE, PP, and other materials.
Biomaster	Pellet	A colorant masterbatch based on biomass plastics with lower environmental impact compared to traditional petroleum-based materials. Provides color hue, dispersion, and pigment content similar to conventional products.

For Engineering Plastics

Product name	Form	Features and applications
Carbon Black Masterbatch	Pellet	A black masterbatch suitable for high-temperature molding of engineering plastics. Imparts an appearance with deep black color and smoothness by preventing glass fiber floatation. Also helps suppress gas generation (mold contamination) during product molding.
DEEP BLACK	Pellet	Highly disperses difficult-to-process fine carbon black particles into polyacrylonitrile (AS) and polycarbonate (PC) resins, offering superior aesthetics compared to conventional carbon black colorants. Also suitable for use in PA, PET, ABS, and other materials.
Aluminum Masterbatch	Pellet	Imparts a high-brightness metallic appearance to product surfaces without coarse particles. Contributes to VOC reduction by replacing aluminum coatings with paint-free solutions. Suitable for use in PC, PET, PA, and other materials.
Surface-Treated Titanium Dioxide for PC	Powder	Recommended titanium dioxide for polycarbonate (PC) resins. Special surface treatment helps suppress hydrolysis of PC, preventing yellowing of molded products.

For Synthetic Rubber

Product name	Form	Features and applications	Catalog
LB Base Color	Sheet	Pigments are highly concentrated and dispersed in SBR rubber, and it can be used with a wide variety of rubber types. By combining various base colors, the desired hue can be achieved.

For Paints and Inks

Product name	Form	Features and applications
Water-Based Colorant	Liquid	Various pigments are dispersed in water. Can be mixed with liquid substances for coloring.
Solvent-Based Colorant	Liquid	Various pigments are dispersed in solvent. Can be mixed with liquid substances for coloring.
Solvent-Free Colorant	Liquid	Various pigments are dispersed in liquid resin or monomer. Can be mixed with liquid substances for coloring.

For Bath Additives

Product name	Form	Features and applications	Catalog
Opacifier	Powder	Special surface-treated titanium dioxide with excellent diffusivity in water, preventing deterioration over time.
