As we all know, the filler masterbatch is made of high-quality calcium carbonate, talcum powder, barium sulfate, and sodium hydroxide powder with high purity and whiteness, which are produced by twin-screw extrusion process. The main purpose of filling masterbatch is to mix raw materials in the production of plastic products, but what are the advantages of using filling masterbatch? Derun Color Masterbatch will explain for you.
Advantages of filling masterbatch:
First, reduce costs:
This is the reason why manufacturers choose the most. Because the filling masterbatch is cheap, but it is not recommended to use the materials below 2000.
Second, reduce product shrinkage:
For example, PP has a large shrinkage rate. When it is a product with many ribs and thick walls, the upper surface of the product generally shrinks and dents, which affects the beauty of the product. After the filler is selected, the shrinkage rate can be effectively reduced, and the flatness of the product surface can be greatly improved.
Third, increase proportion:
There are not many manufacturers selected for this reason, especially the products may be sold in quantity, which is also a disguised way to reduce costs.
Fourth, increase the hardness of products:
In general, such manufacturers recommend using talcum powder to fill the masterbatch, which can improve the hardness by about 20%. Such manufacturers are quite many.
These are the four most obvious points of filling masterbatch, even if we have been asked the most questions.
