What is Masterbatch

Plastic does not start with color. The color you are looking to make requires additives or pigments to get the desired color. Masterbatch is the additive. It comes in Black, White and colors. These different color additives are combined to create the desired color. Marval can combine these additives to create the colors that will give your product the shelf appeal and functionality your product needs

There are 2 types of masterbatch

Color Masterbatch: is used to add color to the plastic. By blending different color additives you achieve the desired color. By blending the colors you can create special effects to help make your product stand out
Additive Masterbatch: is used to give other properties to the plastic. These proerties include the texture of the plastic

Carbon black is a typical ingredient in rubber compounds due to the unique structural properties it imparts to the compound's elastomeric network; however, obtaining uniform dispersions of carbon black in rubber on an industrial scale can be a challenge, and high shear, high energy mixers are usually needed for this purpose. A continuing interest   exist s in producing premixed, well dispersed masterbatches of carbon black in rubber, since mixing the masterbatch and additional raw rubber is inherently easier. To be effective, the carbon black in a carbon black-rubber masterbatch must be well dispersed

Accordingly, there remains a need for improved carbon black-latex masterbatch compositions, and for methods for making and using such carbon black-latex masterbatch compositions. These needs and other needs are satisfied by various aspects of the present disclosure

In accordance with the purposes of the invention, as embodied and broadly described herein, the invention provides an improved carbon black-latex masterbatch composition

While aspects of the present invention can be described and claimed in a particular statutory class, such as the system statutory class, this is for convenience only, and one of skill in the art would understand that each aspect of the present invention can be described and claimed in any statutory class. Unless otherwise expressly stated, it is no way intended that any method or aspect set forth herein be construed as requiring that its steps be performed in a specific order. Accordingly, where a method claim does not specifically state in the claims or de script ion that the steps are to be limit ed to a specific order, it is no way intended that an order be inferred in any respect

Additional aspects of the invention will be set forth in part in the de script ion which follows, and in part will be obvious from the de script ion, or can be learned by practice of the invention. The advantages of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general de script ion and the following detailed de script ion are exemplary and explanatory only and are not restrictive of the invention, as claimed

Masterbatch

A masterbatch provides a convenient way of handling small amounts of critical ingredients, like specialized additives in higher concentration than those occurring in a normal mixture for subsequent dilution with the remainder of the ingredients

Masterbatch Versus Precolor Versus Concentrate Versus Dry and Liquid Colors
A masterbatch is a plastics formulation that contains additives that are essential for the appearance and performance of the final product. A masterbatch can also include colorants. Generally speaking, a masterbatch is comprised of plastic pellets that contain concentrated amounts of additives such as processing aids, colorants, antistats, light stabilizers, fillers, etc. There are many different types of masterbatch vehicles including plastic pellets that are customized to be compatible with the final polymer used in the product. The vehicle can also take the form of powders or even liquids that are compatible with the end use polymers

A color concentrate is usually defined similarly to a masterbatch except it consists only of colorants rather than additional additives that would be found in a masterbatch. Both color concentrates are added or “let down” into the final polymer prior to molding or extrusion into the final product. This blending process is usually a low shear process and can occur in a bucket or a tumbler at the molding machine. The amount of functional ingredients and colorants varies widely but are usually in the range of 0.5% to 5.0%. This is sometimes indicated as a let-down ratio which is a ratio of natural material to the concentrate product. As a rule of thumb, the higher the concentration, the more expensive the product

A precolor or compounded color is a product that is not a concentrate but contains the total amount of colorants and other additives that will be used in the final product. Some molders prefer compounded materials because they do not need to mix the materials prior to processing or because the dispersion of additives and colorants can be more uniform. This is particularly true with dyes when they are formulated in very light colors and low concentrations. If these dyes are not properly dispersed, it may cause color streaks or agglomerates (clumps) in the final product

Liquid colors are usually colorants dispersed in oils that are compatible with the final media. These liquid colors are usually quite viscous and require specialized delivery systems or pumps to add the colors directly into the molding or extrusion equipment. Liquid colors can be extremely high concentrates of colorants and are generally seen as very economical after the initial purpose of the additional delivery systems required. This type of color is best for high-volume application for manufacturers who continuously create the same part in the same color. However, if the customer makes frequent color or design changes, there can be a great deal of waste when making these change outs. Since the colors are an oily liquid, they can cause a great deal of housekeeping and maintenance when compared to masterbatch or other types of pelletized colors.

In contrast, dry colors are best for small runs and quick change overs because they are simply blended with the vehicle prior to processing. Dry color also yields consistent coloration as well as good dispersion

Colorants

The company’s “POP” color masterbatch is said to improve HDPE gloss by 200%, allowing opaque HDPE to compete with PET in more container applications. Compounds with the POP colors reportedly show improved stiffness and melt strength, allowing its use in monolayer bottles. This is unlike with other high-gloss PE compounds, in which a loss of melt strength and crush strength restricts the high-gloss material to the outer layer of a product. Along with its use in mono- and multilayer cosmetics and personal-care containers, the POP masterbatch has US FDA food-contact approvals

Treffert specialises in creating color masterbatches that exactly conform to stated specifications. We achieve this by using exactly the plastic that will later be dyed by the processor as our carrier material. The dye concentrates make it possible to economically self-dye in most plastics processing procedures thanks to their great flexibility in formulating the recipes and provides clean, smooth processing. Dye formulas that have been created can be reproduced even years later with absolute fidelity to the original. Just ask about our color masterbatch es online or contact one of our application engineers in order to discuss the requirements for your product with you in your offices

A color masterbatch, or color concentrate, is a granule used for coloring thermoplastics. It consists of one or more colorants and a polymer-specific carrier resin. The composition of a color masterbatch is called its recipe

Colorants are classified into several categories: organic dyes, organic pigments and inorganic pigments

Dyes are soluble in plastics and can therefore be used for transparent coloration. Pigments remain in their original particle form inside the plastic and need to be dispersed within the plastic

A color masterbatch may contain up to 60% colorant. In the subsequent production process, the colorant is introduced into the melted   plastic
