What is Masterbatch Meaning? Masterbatch Manufacturing Process
1. Masterbatch meaning
Masterbatch is a filler and additive, it is used when manufacturing plastic products to reduce costs and increase product properties. Masterbatch is made from Calcium Carbonate Powder (CACO3 Powder), carrier resins (LLDPE, HDPE, LDPE) and some additives such as: anti-blocking agent, oil,…
The word “masterbatch” mainly means mixture. Masterbatch HS code is 32849999.
2. How to produce masterbatch?
Masterbatch manufacturing process will generally include 3 main steps, and other steps can be optionally added depending on the manufacturer’s needs:
Step 1: Use the formula, create a suitable formula
Masterbatch manufacturers will have different formulas and ratios. Depending on the intended use, create the most suitable formula.
Step 2: Mix ingredients in proportion and melt
After that, all raw materials used for production such as additives, primary plastics, etc. will be put into the mixer and melted.
Step 3: Cool and shape
The molten liquid material will be cooled and cut into small granules.
3. What are the common types of masterbatch?
There are some common masterbatches: color masterbatch, PE masterbatch, PP masterbatch, black masterbatch, white masterbatch, additive masterbatch, etc. They are used to produce plastic products because they are easy to use and easily dispersed with different plastic substrates. In addition, the main reason for plastic product manufacturers to use masterbatch is because it is cheaper than primary plastic, provides many better properties for the product, there are many vendors of masterbatch products so there is no need to worry. about providing abilities.
3.1. Filler Masterbatch:
This is the most common type of masterbatch. The main structure of Filler Masterbatch is powders of various substances (CACO3, BA2SO4, NA2SO4, Talc,…), primary resins, and other additives depending on the purpose of use. Filler Masterbatch granules are white, contain a large percentage of powder of various substances, and the partical size is usually small. Can carry many different types of Carrier Resin (LDPE, HDPE, LLDPE). Trusted by many plastic manufacturers.
Filler masterbatch is divided into 2 types:
– Masterbatch is made up of inorganic substances (minerals) such as CACO3 Powder, NA2SO4, BA2SO4,…
– Masterbatch is made up of organic substances such as tree bark, chicken feathers, and rice husks.
Which type of filler masterbatch to use depends on the needs, price, and application the manufacturer is aiming for. But more popular is Masterbatch from inorganic substances (CACO3,NA2SO4, BA2SO4,…)
How to create Filler Masterbatch :
To produce Filler masterbatch mainly relies on the 3 general masterbatch production steps mentioned above:
Step 1: Choose a formula with the most suitable mixing ratio of ingredients such as additives, minerals (CACO3, BA2SO4, NA2SO4, Talc,…), and primary resin.
Step 2: Melt the mixture at the appropriate temperature.
Step 3: Cool the mixture and put it into a specialized filler masterbatch production machine. The end product is filler masterbatch granules cut into small granules.
3.2. Color Masterbatch:
The structure of Color masterbatch is usually colorants, primary resins, and additives. Color Masterbatch is mainly used to color the final product, making the product more eye-catching. There are many colors made from Color Masterbatch, depending on the needs of the user, some types can be listed as: Red, Yellow, Blue, Green, Purple,…
How to Create Color Masterbatch :
Step 1: Mix primary resins, additives, and other color additives according to a certain ratio and formula.
Step 2: Put the mixture into a specialized production machine. Melt the mixture.
Step 3: Cool the mixture. Then continue to put it into a specialized production machine. The final product obtained is chopped Color masterbatch granules.
3.3.White Masterbatch:
White Masterbatch is a part of Color Masterbatch. Its structure is similar to Color masterbatch, but because its usage is superior to other colors, it is separated into a separate type of masterbatch. The main structure of White masterbatch is Calcium Carbonate Powder (CACO3 Powder), primary resin, and additives, including additives to create white color. Products with outstanding white color are often made from White masterbatch.
How to Create White Masterbatch :
Step 1: Research using a certain formula, then mix primary plastic particles, additives, and white color additives in proportion.
Step 2: Take the mixture and melt it through specialized machinery used to produce color masterbatch.
Step 3: cool the mixture. Then, when completing the related steps, the final product is chopped White masterbatch particles, serving production needs.
3.4. Black Masterbatch:
Black Masterbatch is a separate type of masterbatch, different from White masterbatch or Color masterbatch. The structure of Black masterbatch is primary plastic granules, additives, and carbon black granules (specialized granules for producing Black masterbatch). The function is similar to Color and White masterbatch, used to color plastic products (Black). Almost all black plastic products use Black Masterbatch. The price of Black Masterbatch is not cheap, it is more expensive than color and white masterbatch because carbon black granules have a high price.
3.5. Additive masterbatch:
A combination of organic or inorganic substances (oil, glue, rubber, etc.) added during the production of plastic products to enhance certain properties or functions. When a manufacturer wants a product to have more features that are better, superior, and superior than those of its competitors, it is necessary to pay special attention to Additive masterbatch. It is a filler that easily disperses in plastic products, enhancing product properties such as anti-sticking, UV protection, etc. So the price of Additive masterbatch is not cheap. Therefore, when a plastic product manufacturer wants to use Additive masterbatch, it is necessary to carefully learn about the supplier, its experience, reputation, ability, and qualifications before making a decision.
