Types of masterbatches and their uses

Masterbatchesa are widely used in the plastic industry to add color and other desired properties to the plastic items. The addition of masterbatches is very important for the durability and many functional properties of the final product made with plastic. A materbatche may contain polymer, colorant, or additives formulated together specially to give special property or general properties to the product.

Masterbatches are divided into two parts. They are: pigment masterbatches and functional additive masterbatches. Pigment masterbatches add color to the plastic items. The functional masterbatches are used to add some properties to the final plastic products like, heat resistance quality or weather resistance quality. Some examples of functional masterbatches are: antilog agents, anti static agents and anti UV agents.

White masterbatches come with excellent whiteness and opacity. White masterbatches are made into fine films, tapes, blow molded plastic components and they can also be used with pigments for bright and clean shades. The quality manufacturers made white masterbatches without any molecular waxes and are highly filled.  The white masterbatches find application in single and multiple RF films, Non filaments, PP, HDPE Tapes and filaments, laminated tarpaulin, blow molded items and injections.

Black masterbatches Black Masterbatches Manufacturer in India are widely used because of their cost effectiveness, coloring ability and performance. They are used in large number of plastic as additive to get the desired results as protection from UV rays, desired color and conductivity. The tone exhibited by the carbon black range from alcohol blue to warm brown. These masterbatches finds its applications in plastic and engineering industry, laminated tarpaulin, PE films, telecom duct pipes, HDPE pipes for agriculture, PP fiber and filaments and rotomouled tanks.

Additive masterbatches are used to improve the heat conductivity of the plastic materials so that molding period time is reduced. It also improves the tightness and rigidity of the products while removes the surface light from the products.  These additive masterbatches can be made in various specifications. Some of the additive are : additive like optical brighter , flame retardant , UV stabilizer , anti static agent , PP clarifying agent , blowing agent , anti oxidant MB and flame retardant for PP compounds .

Special effect masterbatches Color Masterbatches Supplier in India are used to achieve the coloring effect of marble, metallic, glitter, wood, phosphorescence, granite, pearl scent effect, fluorescent effect, transparent MB   etc. Other colors that get changed under the influence of ultra violet light or temperature are also possible to get. These batches are used in making toys, CDs, cosmetic bottles and plastic chairs.

The cost of the masterbatches depends on the formulations. The special property formulations make a masterbatch expensive. Some masterbatches that are not packed with some specific properties may not be so expensive. General operating cost cost of product and formulations in a masterbatch affect the cost of the masterbatch.  Processor, machine, its size and capacity and screw type affect the performance of the masterbatche.

Advantages in use of masterbatches and their types

Masterbatches are used to add color or performance enhancing capabilities to the natural or base polymer. This process is done at the plant itself.   The technical benefits of this combination is reduced stock holding of material that is compounded , reduction in cleaning cost , optimum dispersion , increase in performance on the desired level by mixing process . The additional benefits are that the finished products are dust free with no health and safety risks.  The elimination of trial and error development work is ensured because the use of masterbatches ensures consistency in performance and color.  

Masterbatches are mixed with basic polymers in a number of ways.  The two most successful methods are, volumetric or graviametric., In both methods, the masterbatch is added directly to the polymer stream before processing .In volumetric dosing, the low capital is required but here the calibration is done every time the color or batch is changed. On the other hand, the graviametric gives accurate results but the establishing plant is expensive.   

The properties or qualities that are added to the basic polymer may range from UV protection to anti static and metal deactivator. Masterbatches are generally supplied in granules forms. They also come in miniature granules form known as micro granules. The masterbatches are also given in rough cut form, which is combination of small chucks and shreds.

The selection of masterbatches will depend on the end use. Toys and food packaging for example are made with materials, which are made with controlled ingredients. For engineering products, the reliable and high performance properties are added.

Color masterbatches are used in bags, tarpaulin, films, drums, woven sacks, combs and household products and HDPE duct pipes.

While masterbatches offer high opacity and whiteness and find uses in very thin film, blow molded plastic components. The other uses of white masterbatches are in laminated tarpaulin, HDPE tapes, PP and monofilament, multiple or single PE films.

Black masterbatches Colour Masterbatches Supplier in India are used in many applications protection from UV and conductivity is desired.  The other uses of black masterbatches are in automobile and engineering industry. HDPE pipes for agriculture, PE films, filament, laminated tarpaulin, rotomouled tanks, telecom duct pipe, and PP fiber.

Additive masterbatches are used to reduce molding speed by increasing the heat conduction quality of the plastic material.  The masterbatche also increase the rigidity and tightness of the property. It also helps in removing surface light from the plastic products.

  

Special effect masterbatches Black Masterbatches Manufacturer in India have special pigments or fillers to get the effect of different colors. These effects can be marble, metallic, glitter, phosphorescence, wood, fluorescence or granite. The other colors that can change with the influence of temperature or ultra violet light are also possible .These special effect masterbatches  are used in making of plastic chairs , toys , cosmetic bottles and CDs.
