What is a filler masterbatch?
Filler masterbatch, also known as filler masterbatch, is a type of additive based on PE, PP and PS, 20 to 80 of which consists of minerals. The presence of minerals in the filler masterbatch causes the final product to acquire unique characteristics when combined with the plastic product and increase its quality. Filler masterbatches, when added to plastic products, can create properties such as heat stability and stability, high strength, high hardness, etc. Using this masterbatch is an effective solution for improving the physical and chemical properties of the final product and helps reduce its price.
Types of filler masterbatch
Filler masterbatch is produced in various types, each of which is used according to the polymer base of plastic products. The types of filler masterbatch are:
Talc masterbatch
Talc powder, with a translucent appearance and white color, is added as a filler masterbatch to polymers such as polypropylene. This additive increases the thermal resistance and hardness of the product. It also prevents them from waterlogging. This filler is usually used for household appliances, automobiles, etc. The advantages of this type of filler masterbatch include the following.
- Softness
- High chemical resistance
- Increase tensile strength
- Low electrical conductivity
- Non-explosive and non-flammable
- Improvement of product hardness and strength
Calcium carbonate masterbatch
Calcium carbonate masterbatch is produced in different grades with different percentages of calcium carbonate, and its quality depends on the type of powder and processing aids. The calcium carbonates used to make masterbatch have a special structure, so get this type of masterbatch from a reputable manufacturer. This masterbatch is widely used in the production of white products due to its white color and cheap price, and other advantages of this filler masterbatch are known as follows.
- Reduce the final price of the product
- Increase thermal stability
- Increase the colorability and printability of the product
- Increase productivity
- Produce a white product without the need for a color masterbatch
In addition to these two commonly used examples, there are other filler masterbatches such as mica, barite, kaolin, and wollastonite, and you can use any of these filler masterbatches depending on the plastic product being produced.
Benefits of using filler masterbatch
Filler masterbatches used in injection molding, film, envelopes, bags, etc., offer benefits that make their use very economical for plastic product manufacturers. These benefits include:
- Reduced raw material costs
- High speed in mold cooling and increased output
- Reduced need for white color masterbatch
- Increased product hardness and strength
- Increased dimensional stability
- Reduced water absorption
- Increased heat resistance
- Resistance to burning
- Reduced shrinkage
Of course, these benefits vary across different types of filler masterbatches. For example, one of the benefits of calcium carbonate masterbatches is that they do not require a color masterbatche, and if other filler masterbatches such as talc, barite, etc. are used, a color masterbatche must be used.
Application of filler masterbatch
The main reasons for using filler masterbatches in various industries are to reduce the final price of the product and increase its weight. This type of masterbatche is usually used to produce plastic products and transparent and translucent films. In the plastic products industry, filler masterbatches, when added to solid and liquid products, increase their ductility and resistance and are effective in changing the weight and density of the product. Using a filler masterbatche such as calcium carbonate helps to better decompose plastic and is not dangerous to humans or nature. In general, filler masterbatches are used for the following purposes.
- Automotive Parts Manufacturing
- Household Products
- Water and Sewage Pipes
- Plastic Packaging
- Injection Molding Manufacturing
- Bags and Envelopes
And in general, for any plastic product that needs to increase weight and improve properties, this masterbatch can be used to help reduce production costs.
Conclusion
Filler masterbatch is one of the important types of additives in the plastics industry that is used to produce a wide range of plastic products. Filler masterbatch is known by this name because it helps to increase the weight of the polymer product and has many advantages that we have examined in this article. This masterbatch comes to the market in various types, and to use it, you should pay attention to the polymer base of the product. Using this masterbatch in the plastics industry brings great economic savings and in addition to helping to improve the properties of the product, its final price is reduced.
