Color Masterbatch: The Premier Solution for Industrial Plastic Coloration

Methods to Color Plastic Beyond Color Masterbatch

Industrial plastic manufacturers have several options to achieve vibrant, consistent colors. Common approaches include direct pigment addition, precolored resins, and the industry-standard color masterbatch.

Pigments

Pigments are insoluble organic or inorganic particles incorporated into the polymer matrix to impart specific hues. Organic pigments tend to form agglomerates, leading to spots and specks, whereas inorganic pigments such as titanium dioxide, metal oxides, and carbon black disperse more uniformly. Titanium dioxide is the most widely used inorganic pigment in the plastics industry due to its brightness and opacity.

Precolored Resins

For processors lacking experience with custom color matching, precolored resins offer a turnkey solution. The pigments are fully polymerized into the resin, ensuring consistent color across batches. RTP Company’s colorists guarantee match accuracy and lot‑to‑lot consistency, delivering custom colors in as little as five days and precolored resins within 5–10 day lead times.

Color Masterbatch

Masterbatches consist of concentrated pigments dispersed in a polymer carrier resin. During molding, the masterbatch is blended with the base resin at a predetermined ratio to achieve the desired shade. Masterbatches are the most economical and flexible method, available in small volumes and compatible with a wide range of base resins.

Color Masterbatch for Industrial Plastic Applications

Colored masterbatches incorporate additives to provide additional properties such as waterproofing, anti‑fog, anti‑block, flame retardancy, antioxidant protection, fillers, foaming agents, optical brighteners, detergents, process enhancers, fragrances, anti‑slip agents, UV absorbents, and inhibitors.

Typical applications include:

• Film blowing and extrusion – packaging films, elastic films, agricultural and construction films, diaphragms, garbage bags, multilayer bags
• Blow molding – bottles and containers
• Injection molding – home appliances, toys, garden furniture, pots, buckets, boxes, electronics, barrels
• Extrusion of sheets, fibers, and cables

With a vast color chart and countless shades, achieving the exact hue for a product often requires sample analysis. Sunrise Colors Vietnam specializes in precise color matching from product samples, ensuring the highest quality masterbatches with outstanding physical and chemical performance.
