Mainly used for PP can reduce the temperature of 30-50 degrees.
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 general masterbatch dosage is 20%-30%, and the product is 0.2%-0.3%. , too much will affect the printing effect of the product.
In the production of masterbatch, sometimes the material is easy to accumulate the feed opening, which is mainly caused by the air entrainment of talcum powder. During the production, it should be heated and stirred to melt the wax and wet lubricate the stone powder or add white mineral oil.
Moisture absorption and defoaming masterbatch
Moisture absorption and defoaming masterbatch can mainly remove moisture contained in plastics and unknown low molecular volatiles, so that plastic products without water bubbles, so as to ensure the quality of products can be subtracted while drying process.
Flame retardant masterbatch
Flame retardant masterbatch is mainly used in flame retardant modification applications.
Foaming masterbatch is commonly used in PE, PP, EVA and so on.
