The Special Function Masterbatche can be divided into cooling masterbatch, brightening masterbatch, moisture absorbing masterbatch, flame retardant masterbatch, foame masterbatch, etc.
The cooling masterbatch is mainly used for PP, which can lower the temperature by 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 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. When the masterbatch is strengthened, sometimes the material is easy to accumulate in the lower mouth. It is mainly caused by the entrained air of talc powder. It should be heated and stirred during production to melt the wax, wet lubricating stone powder or white mineral oil.
The moisture-absorbing and defoaming masterbatch can mainly remove the moisture contained in the plastic and the unknown low-molecular volatiles, so that the plastic product has no water and no bubbles, so that the drying process can be reduced while ensuring the quality of the product.
Flame Retardant Masterbatch is mainly used in flame retardant modification applications.
Foam Masterbatch is commonly used in PE, PP, EVA, and the like.
