There are many kinds of masterbatch, each of which has corresponding effects. Functional masterbatch refers to the concentrate of various plastic additives. Direct addition of additives is not easy to disperse and the use efficiency is not high, because the form of masterbatch is commonly used. Add to.

The feature of functional masterbatch is: particle size: the granular solid composed of the particle size of 0.1~3mm is a powdery solid. 0.1mm (100μm) is a powder composed of fine particles; 1~10μm is a fine powder; 0.1~1μm is an ultra-fine powder; 》3mm is a broken solid block. The smaller the particle size, the denser the resulting mixture.

However, the smaller the particle size of the same solid, the easier it is for the particles to adsorb and agglomerate each other, and it is not easy to open when mixed with another solid particle, and it is also difficult to disperse and separate in the plastic melt.

Moisture absorption and defoaming masterbatch: it is composed of metal oxides, fat additives,

Flame retardant masterbatch: it is composed of flame retardant and resin additives

Conductive masterbatch: the long copper fiber and resin are wrapped and pelletized.

Foaming masterbatch: It is composed of composite foaming agent, lubricant, dispersant, and coloring agent

Anti-ultraviolet masterbatch: It is made by superposing two kinds of anti-ultraviolet agents, and then with carrier, dispersant and other additives.

Weather resistant masterbatch: It is composed of light stabilizer, resin and auxiliary agent.

Cooling masterbatch: mainly used for PP, which can be cooled to between 30 and 50 degrees

Brightening masterbatch: also called bright masterbatch, the purpose is to improve the brightness of the product, the general amount of color masterbatch is 20%-30%, and the product is 0.2%-0.3%. Too much will affect the saturation of the product and the printing effect .

Perfume masterbatch: the fragrance can last for 10 to 12 months, which can be used in toys and daily necessities
