There are many types of masterbatches, each of which has corresponding effects. Non-woven functional masterbatches refer to the concentrates of various plastic additives. Direct addition of additives is not easy to disperse, and the use efficiency is not high. Add in the form of granules.

The non-woven functional masterbatch is characterized by: 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 ultrafine powder; >3mm is a broken solid block. The smaller the particle size of the non-woven functional masterbatch, the denser the resulting mixture.

The smaller the particle size of the same solid, the easier it is for the particles to adsorb and agglomerate each other. 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.

Classification of non-woven functional masterbatch:

Hygroscopic 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 auxiliary agents.

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 lasts for 10 to 12 months, which can be used in toys and daily necessities.
