Organic Pigments and Its Manufacturers

Organic pigment leads to colored material made of an organic aggregate with pigment characteristics. Some common types of organic pigment including - Azo Pigments, Lake Pigments, Phthalocyanine Pigments, and Quinacridone Pigments. They are all known as artificially synthetic organic compounds whose process and equipment required by such kinds of pigments are frequently the same as that required by organic dyes, consequently normally manufactured in the dye industry. Nevertheless, as colorants, they are very different from the organic dyes.

The organic pigment has no connection to the colored substance, instead of being attached to the facade of the colored substance through additives to achieve the purpose of coloring the products.

Insoluble natural compounds
Organic pigment manufacturers is a class of insoluble natural compounds of high coloring strength property which means that they have extremely small solubility in the water when dissolved, organic solvent, and various kinds of factors.

Organic pigments should also have a series of pigment properties, namely sunshine-resistant, organic solvents resistant, resistant to flooding, alkali resistant, acid-resistant, heat resistant, and excellent dispersion property in the application medium, and many more.

From the prospect of the chemical structure, organic colorants are similar to dyes. The only difference between these two is that the former has no connection to the substrate while the latter has a certain connection.

Excellent performance properties
Organic pigments are mainly used in the industry such as the ink industry, plastic industry, rubber industry, and more areas also as they possess excellent performance properties such as color, durability, mobility, and appropriate viscosity to the inks.

With different purposes and conditions, the demands for the organic pigments are also different based on their performance properties but the general specification is a bright color, heat and light, excellent dispersion, strong coloring power, less oil absorption, and strong hiding power.

Get the Best Quality Plastic Pigments in the Market

Seeking one of the best manufacturers and suppliers of plastic pigments in the chemical industry then you are in the right place. Despite, the plastic pigment is chemical compounds used to color plastic products. These compounds come in a form of pigments. The type of colorant is taken based on the type of polymeric resin, which needs to be processed.

The consequence of colorants on injection molded plastic parts is complicated. The method requires several important steps. When it comes to the coloring selection, it will depend on the factors including the actual plastic material involved in it and the final application, which may require demands on properties including durability, environmental factors, and cost.

Amazing performance properties of plastic pigments
Suitable plastic properties include melt flow rate, melt or processing temperature, structure (crystalline or amorphous), transparency, the reinforcements, and fillers being used.

Despite the fact, pigments do not evaporate into the plastic, whereas dyes go into solution and are easily mixable. They are applied to transparent plastic products where powerful tinting is needed. However, dyes give brilliant color, yet do not lose surface imperfections as well as pigments do.

Applications of Pigment when used for plastic material
Industrial use of pigment for plastic includes the manufacturing of toys, bubble wraps, and most of which require strict adherence to certain industry norms. Plastic Pigments deployed in the plastic industry incorporates various categories of compliances such as food packaging materials, plastics directive, Toy safety, and many more.

With globally active production facilities, convenience, and high-quality service centers, there are many manufacturers and suppliers available in the industry and can develop pigment preparations which suit their customers’ specific needs and requirements.

Things to Know While Choosing Pigments

 Today, there are several China pigment manufacturers and suppliers available in the chemical industry providing a wide variety of synthetic and natural pigments with their unique performance properties. Despite, some of the colorants are more impact resistant than other colorants, while some of them have better characteristics such as more UV resistance. Let's take a glance at the major performance properties of the pigments that include: 

Property #1: Weather ability or Aging
The pigments must exposure to sunlight. Pigments that are mainly used in the plastic industry should be selected for their weather resistance characteristics that are closely related to lightfastness. It adds an extra dimension of atmospheric situations and some artificial lights can have adverse impacts on the useful life of the plastic products. Consequently, the pigments used especially for plastic products require UV protection and weather-resistant properties.

Property #2: Lightfastness
Pigments must always hold a lightfastness property that describes how immune to fading the pigment is when it is exposed to light. Though, inorganic pigments are recognized to be more lightfast than organic pigments. Additionally, the black pigment is usually considered the most lightfast.

Property #3: Insolubility
Pigments used for plastic products should be insoluble in the medium and must not react with any of the components when added. Notably, organic pigments may dissolve to a limited extent in organic solvents whereas inorganic pigments may be influenced by other components.

Property #4: Transparency
Transparency property is measured as the greater the color difference, the higher is its transparency. Transparency is obtained by reducing the color particle size as possible that is achieved by surrounding the pigment particles as soon as they are produced with a coating. Despite the fact, it prevents the growth of crystals. For example, iron oxide pigment can be opaque or transparent.
