Masterbatches

Masterbatch is a dye in the form of granules of various shapes for coloring the polymer at the stage of formation of a polymeric mass in the melting process.

In most cases products from polymers colored directly on the stage of production of the finished product. For coloring in the composition of the feedstock (polymer) masterbatches (granular dyes) are introduced. These masterbatches consist of polymer carrier and color pigments. This technique of staining of polymers is the most technologically advanced method.

Since masterbatches are made in the form of granulate, it makes it possible to mix dye with the base material (polymer), and easy to dispense concentrate. Pigment masterbatches in already previously distributed across the polymer base of granulate so that their uniform distribution throughout the volume of the material. Such a method is more manufacturable plastics staining and least time-consuming compared to the use of liquid and powder pigments and dyes.

What the difference between usual concentrates and masterbatches (or superconcentrates)? The percentage of pigment in the polymer base. If the concentrate proportion of the pigment is more than 20-30%, you can call it as "masterbatch" (or superconcentrate), that is, a concentrate with a high content of pigment. The process of adding of masterbatches in the initial polymer raw material is the least complex compared to other methods of coloring plastics. This method involves the minimum cost of the dispensing equipment and the least effort. The method of adding of the masterbatch in the polymer is determined mainly on the production equipment capabilities. Depending on the desired degree of dosing accuracy, volumetric or gravimetric dosers of various action types can be used, but if inappropriate for costly dispensers and for small production volumes, manual mixing of masterbatch and the main raw material can be applied.

Dosage

Percentage of adding of our masterbatch can be from 0.5 - 1% in the casting or blow molding process and up to 5% in the extrusion of thin films of LDPE, HDPE, PP and other materials.

Raw materials and our product

We produce only high-quality masterbatches and take into account the specificity of the product to be painted. Here you can purchase:

• White mastebatches
• Black masterbatches
• Color masterbatches
• Modifying additives

In our manufacture we use only high-quality raw ingredients - the basis of our masterbatches - LDPE (low density polyethylene) and of LLDPE (linear low density polyethylene). We can also produce masterbatches based on PP (polypropylene) and PS (polystyrene). In the manufacturing process we use imported organic and inorganic pigments, that do not migrate to the surface of the material, have a high-precision colour reproduction and resistance to the temperature regime of processing. Our raw components are not exposed to UV light and weathering.

White mastebatches

White masterbatches that you can buy from us may contain from 30% to 70% TiO₂ (titanium dioxide), in addition we can offer you a milky white or snow-white shades of masterbatches. We use high-quality imported TiO₂ (titanium dioxide) in the production of our products, whereby our white masterbatches has a high degree of opacity, a powerful bleaching and resistance to high temperatures.

Black masterbatches

Black masterbatches that we produce have high carbon content. They contain up to 60% of high-quality carbon black. Carbon concentrates have excellent dispersion and resistant to thermal effects, they are cost-effective products. This type of products we produce have a carbon content from 20% to 60%, besides the different carbon concentrates give the finished product a haze or shine. Application area:

• Automobile industry
• Pipes and fittings
• Electricity/Electronics
• Cables
• Film materials
• Garbage bags and packages

Our black masterbatches dyed products of polyolefins obtained by blow molding (cans), extrusion (film material), or by injection molding.

Color masterbatches

Color masterbatches of our production have basic and intermediate colors (to select a specific color, we suggest you use the RAL and Pantone tables posted on our website in the section Catalogs Of Colors). The advantages of our color masterbatches:

• Provide uniform color of mixture
• Do not pollute and do not dust workplace when changing color
• Provide a simple cleaning of the working equipment
• Create a small amount of waste
• They are very economical in dosage

We can develop any interesting shade for your product as well as to give to masterbatch some special effects: metallic, gold, bronze or silver shades, fluorescent and pearlescent, "marble" and "granite chips" texture etc. Thanks to a trained and specialized staff we have the possibility of rapid preparation of samples from an existing range of products (more than 40 standard colors and shades). Or, our team of experts will develop any masterbatch for you in shortest time possible according to the international catalogs RAL and Pantone, considering your criteria to the conditions of use or features of your manufacture process.

Modifying additives

We offer additives of our production for the manufacture of products of polyolefins:

Slip additives: Prevents adhesion of film-coated surfaces to each other, as well as adhesion to metals, provides the sliding effect
Anti-block additives: Prevents blocking that occurs during the production of the film and creates an easy-slip effect
Antistatic additives: By preventing the formation of static electricity on plastic products, eliminates attraction of dust and foreign substances to products
UV additives: Prevents yellowing of the plastic materials that are exposed to UV radiation. As well as extending the life of the products
Cleaning additives: These ones designed to quick changing color while manufacture process. Reduce waste of production.
Processing additives: Additives used to improve the following performance parameters:

• Elimination of surface defects arising from anomalies of viscosity and excessive shear stresses
• Preventing the formation of deposits and carbon deposits on the molding tool
• Increase in productivity
• Easing of the processing of secondary polymers
