AN INTRODUCTION OF COLOR MASTERBATCH

BLOG 29/12/2023 8:48:53 AM 195

Plastic granules known as color masterbatches, or color concentrates for plastics, are primarily used to color polymers. The colorants and the carrier resin tailored to the particular polymer make up the two primary parts of the color masterbatch. Processing additives like zinc, oil, wax, etc., and/or fillers (often powdered calcium carbonate) are also included in some particular formulas. Have you ever thought about how manufacturers manufactured this type of masterbatch, which is widely utilized every day in almost every element of life with a broad range of applications? You can learn more about this from this article.

What does it contain?

Before going into further detail about the materials used to create this kind of masterbatch, we sincerely wish to dispel several myths surrounding the plastics business. The color masterbatch is not a pure pigment or coloring, to start. On the other hand, pure pigment/colorant, or any kind of dyeing agent, is less concentrated than the original colorants, which are typically broken down into three subgroups: organic dyes, organic pigments, and inorganic pigments. This is because pure pigment/colorant is only a portion of masterbatch, which also contains carrier resins. The most popular color concentrates for plastics are black and white masterbatch; carbon black (P or HAF) and TiO2 (rutile/anatase), respectively, are typically responsible for these masterbatches' striking colors.

Main purposes of using Color Masterbatch

Color catches the eye and draws attention to the design's focal point. There is no denying the significance of colors in our lives. For this reason, people attempt to alter the appearance of the majority of commercial products in order to offer a wider variety of colors. Color masterbatch was developed in the plastics industry to fulfill this need by adding vivid and striking color to plastic goods and their uses. Our products come with a number of advantages, such as ease of use, high color concentration, good color quality, stable color shade, good light fastness, heat resistance, easy mixing during processing, low environmental impact, and savings on both processing time and cost (pigment drain). These days, color masterbatches are used in a variety of organizations and industries with several appliances, such as textiles, automotive, packaging, building, electronics and electrical, and so on.

Is it colored resin?

No, color masterbatch differs slightly from colored resins, despite the fact that they both contain the same major ingredients. While color masterbatch may contain 20 - 75% colorants (the actual dyeing agents, which could be powder or liquid pigment), colored resins used in the manufacture of plastic products contain significantly less of these colorants. The proportion of color concentrations in finished products typically ranges between 2 and 10%. This is also the dosage that most masterbatch manufacturers (such as StarPoly) recommend for their customers.

How to tell the Color Masterbatch is high-quality?

Color concentrates for plastics must meet several requirements in order to be exported to the global market, including even granule size (approximately 3mm). They should also be of consistent quality with good color dispersion. Masterbatch containing high-quality ingredients and 100% virgin resin can assist end products in achieving a smooth surface with good printability and durability.

StarPoly - manufacturer of color masterbatch

Each sort of color masterbatch is manufactured by a particular formula under a tightly regulated procedure, depending on the intended color (and even unique effects). Based on each customer's requirements and after carefully considering various factors such as viscosity, melting temperature, environmental conditions, chemical resistance, FDA suitability, and so on, a specific recipe is developed at our company to ensure our products will meet any requirement, even the most demanding.
