Plastic products become an integral part of our everyday life; the colour for the plastics gets from the Masterbatch. Masterbatch is an additive material that usually comes in the solid state like small pellets that are used in the plastic industry for adding the colour or any other properties such as strength, antibacterial, conductivity, anti-static etc., to the plastics. Masterbatch is a mixture of concentrated pigments or additives, which is manufactured during a heat process. Carrier resin along with different types of additives is mixed extensively during a heat process, and then cooled to make into granular shape.

Masterbatch comes in different types of colours like black, white, and coloured masterbatches and in different features like anti-microbial masterbatch, anti-static masterbatch, additive masterbatch, special effect masterbatch and filler masterbatch.

Reasons for using Masterbatch:

• Masterbatch comes in pellet form, making it far less messy to store, move and manipulate than powdered pigments or any other types of additives.
• It is simpler to feed and handle colour concentrates during the manufacturing process when masterbatch is used.
• The pigment/additives can become airborne during manufacturing processes, potentially contaminating adjacent manufacturing lines.
• Pigment/Additives does not disperse well on its own, but masterbatch is designed and engineered for optimal dispersion in a polymer matrix, contributing to excellent distribution throughout the final product.
• Less pigment/additives is required when housed in masterbatch than when added in raw, powdered form due to dispersion chemistry.

 Where we can use Masterbatch?

The use for Masterbatch is for its industrial advantages, the following are the main application area’s for Masterbatch in industries:

• Extrusion coating
• Films
• BOPP
• Injection moulding
• Blow moulding
• Non-woven
• Multi-filaments
• Thermo-forming and pipes, and so on…

What are the advantages of using Masterbatch?

1. Masterbatch are extremely cost-effective.
2. Masterbatch offers better colour consistency of products.
3. Masterbatch allows for better control of opacity and transparency of coloured products.
4. Additive ingredients are included in masterbatch in predetermined ratios, minimizing the chance of variance during processing.
5. Masterbatch can contain additive concentrates that deliver desirable traits such as UV stability, antioxidants, antibacterial, anti-static, etc.

Masterbatch is a liquid or solid additive for plastics used for colouring plastics commonly known as a colour masterbatch or imparting other properties to plastics referred as an additive masterbatch. Alternatively, a masterbatch can be defined as a concentrated mixture of additives and/or pigments encased, to ensure better dispersion, homogeneous compound and minimized batch to batch variation of the critical material, during a heat process into a carrier resin that is cooled after and sliced into a granular shape.

Masterbatch carrier material can be based on a universal carrier such as wax or a specific polymer, compatible with the natural polymer or even identical- polymer specific. Such as LDPE can be used as a carrier on nylons and polyolefins, polystyrene can be used for ABS. This is done to avoid modification of the resultant plastic properties. Similarly, the specification of the resin is very vital. The concentration of the additive in the masterbatch is much higher than in the final polymer, but the additive is already properly dispersed in the host resin. Their use is an analogue of uses of ferroalloy for adding alloying elements to steel.

The colour masterbatch consists of pigments or dyes, carriers composed of; uniform pigment or dye evenly attached to the resin obtained in the aggregate to make the tinting higher than the pigment itself. Simply a colour masterbatch is an aggregate made by adding ultra-constant pigments or dyes to the resin. In addition to adding colour, other properties can be incorporated into the masterbatch; such as antimicrobials, UV stabilizers, anti-statics, fire retardants, antioxidants, fragrances.

Masterbatch is ideally designed to suit a wide range of polymers. Since the pigments in the masterbatch are not bio-available, their product is a health and safety proposition as the pigment can become airborne during manufacturing processes, potentially contaminating adjacent manufacturing lines. Since they are in pre-mixed compositions, their use eliminates the issues with the additive or colorant insufficient dispersion or dispersion. It also offers better colour consistency of products from lot to lot, and even within lots than raw pigment. It is simpler to feed and handle colour concentrates during the manufacturing process when masterbatch is used.

Are you willing to improve your product’s shelf life or develop better processing conditions? Untreated plastic objects are vulnerable to attacks from fungus, bacteria and other harmful microbial organisms. This leads to bad odor, degradation and powdering of the polymers in the product. At Ishu International, we are involved in the manufacture, development and supply of high-quality Antibacterial Masterbatch which is extremely useful in protection from a wide range of bacteria, at household and hospitals. Polybooster Masterbatch is available in a variety of resins and different kinds of active ingredient loadings. It can be developed based on the required addition rate.

We, at Ishu International, can also manufacture additive blends based on your special requests according to your industry. Our technical experts can help you by creating goods that will have all the properties that you want.

Properties:

Antibacterial Masterbatch helps enhance the antibacterial properties of the plastic products as plastic is easily susceptible to infestation by microbes and bacteria. The appearance of Masterbatch is usually white, sometimes black, and also available in colors. It can be added at any stage of manufacture. Antibacterial Masterbatch can be used in Agriculture industry in making films, and is regularly used in coated fabrics like tents and raincoats, foam, cushions, insulation and gaskets, toys, medical disposables like syringes, and household products like shower curtains.

Advantages:

Antibacterial Masterbatch has a wide range of advantages and applications. It can be used in indoor plastics which are used on a regular basis at home, such as in the kitchen and bathroom. It has several benefits in hospitals and can protect against attacks from bacteria, fungus, and microbes. A truly important benefit of Antibacterial Masterbatch is that it has a low environmental impact and is relatively safer to use. It helps maintain the freshness and cleanliness of the surroundings at home. A significant use of Antibacterial Masterbatch is that it can be used in a plethora of polymer systems such as PP, PVC, PE, Nylon, Polyurethanes, Polyester and Rubber. It has an important role in protecting consumer appliances, sports and recreation equipment, supplies for construction, interiors of transportation, films, and fibers in the textile industry, food processing, and machinery, and general household goods that need to be immune to bacterial or microbial attacks.

Overall, Antibacterial Masterbatch protects against bacterial and several types of fungal attacks ad is essential to improve the shelf life and quality of the products used every day in different industries.
