Plastic Dye – Adding Color To The Prosperity Of Plastic Industry

It is well known fact that proper color schemes and right shades play a vital role in enhancing the beauty of any object. That is why manufacturers of industrial as well as consumer products lay a lot of stress on using the right kind of dyes that will make their products attractive and eye catching. Over the years the use of plastic in various manufacturing process has increased tremendously and there is an unending demand of the wide range of plastic products that can be put to numerous uses in everyday life. In such a scenario, plastic product manufactures try to make their merchandise more striking for customers, by using a wide variety of plastic dye.

In the plastic industry, perfect color forms an integral aspect of every product and hence has to be chosen with considerable attention. The choice of color not only depends on the end use of the product but also upon the impact of the color on the product being manufactured. Most often manufacturers are unaware of the negative effects that the wrong choice of color can have on the overall, strength and durability of the plastic product.

Generally, dyes and pigments are the most common types of colorants used in the plastic industry. Even though both these colorants use the technique of visible light absorption and scattering, to impart color to the target object, there is a limited use of dyes in the plastic industry mainly because of the fact that the dyes used in this industry need to be strong, show good heat stability and be transparent. Plastic dye is the most common type of dye that is used for coloring plastics. These solvent based dyes can be used for coloring a wide range of materials including acetates, nylon, polyester, acrylics, PVC, PMMA, PETP, polystyrene and styrene monomers.

The choice of using a dye or a pigment to impart color to a plastic product largely depends on the type of base polymer being used for manufacturing the product. While pigments are a preferred choice for coloring polyolefins, dyes are primarily used for imparting color to polycarbonate, polystyrene, acrylic, and other types of polymers, mainly because they exhibit great color strength and transparency. Another important and decisive factor in choosing the coloring agent is its compatibility with the base resin, which ensures the prevention of a color shift over the time.

All You Need To Know About Solvent Dye

Solvent dye, which is also popularly known by the name of oil dye, is the type of dye that is generally soluble in an organic solvent. While most dyes exhibit the property of ionization, a solvent dye generally does not ionize. These dyes color by getting dissolved in the targeted material, which is generally a lipid or a non-polar solvent. The naming pattern of solvent dyes has the word solvent followed by the name of the base color and a unique number. The classification helps in specifically identifying the dyes through the name of the stated color and its primary mechanism of staining.


A solvent dye is generally introduced in the form of a solution that is dissolved in an organic solvent. A large number of solvent dyes are basically azo dyes, which have been molecularly re-arranged to get rid of their ionizing capability. The molecular re-arrangement also enables these dyes to become soluble in non-polar solutions such as triglycerides. Some other common solvents for solvent dyes include alcohols, ethers, ketones, aliphatic and aromatic hydrocarbons, oils, fats, waxes and chlorinated hydrocarbons. Although, being soluble in an organic solvent is a basic physical characteristic of a solvent dye, there are some important applications, where the dyes need to be applied directly instead of first dissolving them in a solvent.


The fact that solvent dyes are soluble in non-polar mediums lends them a versatility that makes them perfect for use in a wide range of applications. They are used in industries on a large scale for foil printing, printing inks, marking pens, ball point pens, candles and other waxes, polishes, leathers, wood stains, acrylic resins, varnishes and shellacs. They are even used to signal smoke and have a diverse usage in the pyrotechnics industry. Additionally, these dyes are also widely used in the automotive industry for coloring lubricants as well as in the industrial cutting sector.


However, the most common and widespread use of solvent dyes is in the plastic industry where they are use to impart color to a wide range of solid materials that include acetates, nylon, polyester, acrylics, PVC, PMMA, PETP, polystyrene and styrene monomers. They are also used as integral components in the manufacturing of biological stains used to distinguish distinct cell structure components that play a vital role in medical diagnosis and scientific research.

All You Need To Know About Basic Dye

When people think about dyes, the image that comes to their minds is generally of colored aromatic compounds having the ability to ionize, making them capable of interacting with tissue components that are oppositely charged. Dyes are generally classified as basic dye and acidic dye depending on the type of charge they possess. Acidic dyes are negatively charged dyes that can interact with positively charged tissue components, while basic dyes are positively charged and can bind themselves with negatively charged tissue constituents.


The naming scheme of basic dyes follows a specific pattern in which the word “Basic” is followed by the name of the base color and a unique number. For example, Basic Red 9 and Basic Green 4 are the names of some basic dyes. The names of the basic dyes just provide the functional and color information about the dye and do not convey any information related to the chemical properties of the dye. It is also important to understand that dyes having unique names but similar numbers are not related in any manner. For example, it is wrong to assume that basic Brown 4 and basic Violet 4 are related in any manner.


The colored part of a basic dye exhibits a positive charge, when the dye is dissolved in water. They are generally very bright and washfast hence are largely used to dye acrylic fibers. However, they are not sufficiently washfast to prove as good dying agents for protein fibers such as wool. Moreover, in order to make them bind with cotton fiber, the fiber first needs to be mordanted as otherwise the dye tends to fade quickly when exposed to sunlight. The natural tannin content of reeds, raffia, grasses and barks acts as a mordant making it possible to use basic dyes efficiently with these materials.


Like most other dyes, basic dyes are also toxic in nature and need to be handled with extreme care. It is vital to follow all the safety precautions and obtain the MSDS information before purchasing any type of basic dye. Although most companies supplying basic dyes readily provide the MSDS information, it is advisable not to purchase these dyes from those few companies that are not willing to give this information as it can prove extremely hazardous to the health and safety of the buyers. It is also advisable to buy these dyes in liquid or paste form, whenever possible.
