There are many types of functional masterbatch, and various problems will be encountered in the process of use. Today, we will answer the questions that are more common in functional masterbatch.

First, what is the main composition of the filled masterbatch?
Answer: 1). Filler: such as calcium carbonate, talcum powder, etc.

2). Coupling agent: such as carbonate silane.

3). Dispersing agents: such as polyethylene wax and stearate.

4). Carrier resin.

Second, the cooling masterbatch is mainly used for those plastics. How much can it be cooled?
A: Mainly used for PP can lower the temperature by 30-50 degrees.

Third, what is the brightening masterbatch? What is the general dosage?
A: Brightening masterbatch is also called bright masterbatch, the purpose is to improve the brightness of the product. The main brightener is ethylene bis stearamide, the amount of color masterbatch is 20%-30%, and the product is 0.2%- 0.3%, too much will affect the printing effect of the product.

Fourth, we use the return material for new injection molding. In addition to black, which color masterbatch coloring effect is better?
A: According to our experience, it is also possible to use silver masterbatch and silver-gray masterbatch, silver masterbatch with lead silver powder. It has a strong hiding power.

5. What problems will be raised when the masterbatch is produced, and how can it be solved?
Answer: The material is easy to accumulate the material outlet. It is mainly caused by the entrained air of talcum powder. It should be heated and stirred during production to melt the wax, wet lubricating stone powder or white mineral oil.

6. What is the functional masterbatch? Why is it in the form of masterbatch?
Answer: The functional masterbatch refers to the concentrate of various plastic additives. The direct addition of additives is not easy to disperse, and the use efficiency is not high, so it is often added in the form of masterbatch.

7. What is the role of moisture absorbing and defoaming masterbatch?
Answer: It is mainly to remove the moisture contained in the plastic and the unknown low-molecular volatiles, so that the plastic products are free of water and bubbles, so that the drying process can be reduced while ensuring the quality of the products.

8. How is the moisture absorbing defoaming masterbatch composed?
Answer: The moisture-absorbing defoaming masterbatch is composed of metal oxide + resin + additive.

9. How is the filled masterbatch used and composed?
Answer: The filler masterbatch is mainly used for filling and modification. It is made of filler + resin + additive.

10. How is the flame retardant masterbatch used and composed?
Answer: Flame retardant masterbatch is mainly used in flame retardant modification. It is composed of flame retardant + resin + additive.

11. How to make conductive masterbatch?
A: The long copper fiber and resin are coated and pelletized.

12. How is the foamed masterbatch composed? What are the commonly used materials?
Answer: The foaming masterbatch is composed of a composite foaming agent, a lubricant, a dispersing agent and a coloring agent, and is commonly used for PE, PP, EVA, and the like.

13. How is the anti-UV masterbatch formed?
A: It is made by combining two kinds of anti-UV agents, and then adding additives such as carrier and dispersant.

14. What is the composition of the weathering masterbatch?
Answer: The weathering masterbatch is composed of light stabilizer + resin + additive.
