Kinds Of Functional Masterbatch

Masterbatch is divided into many kinds, each with corresponding efficacy, functional masterbatch refers to a variety of plastic additives concentrates, direct addition of additives is not easy to disperse, the use of efficiency is not high, because the form of masterbatch is commonly used to add.

Functional masterbatch features are: particle size: particle size 0.1 ~ 3mm composed of granular solids for powder solids. 0.1mm (100μm) for particles composed of powder; 1 ~ 10μm for fine powder; 0.1 ~ 1μm for ultra-fine powder; 》3mm particles for broken solid blocks. The smaller the particle size, the more dense the mixture obtained.

However, the smaller the particle size of the same solid, the easier it is to adsorb and clump between the particles, which is not easy to open when mixed with another solid particle, and difficult to disperse and separate in the plastic melt.

Moisture-absorbing and defoaming masterbatch: is composed of metal oxides, fat additives, and

Flame retardant masterbatch: is composed of flame retardant, resin additives

Conductive masterbatch: the long copper fiber and resin, wrapped, cut grain and completed

Foaming masterbatch: is composed of compound foaming agent, lubricant, dispersant, coloring agent

UV resistant masterbatches: made by overlapping two kinds of UV resistant agents, and then and carriers, dispersants and other additives

Weather-resistant masterbatch: It is composed of light stabilizer, resin, and additives

Temperature reduction masterbatch: mainly used for PP can lower the temperature to between 30 and 50 degrees

Brightening masterbatch: also called brightening masterbatch, the purpose is to improve the brightness of the product, the general amount of color masterbatch is 20%-30%, the product

It is 0.2%-0.3%, too much will affect the saturation and printing effect of the product.

Aroma masterbatch: The fragrance retention time can reach 10 to 12 months, which can be applied to toys and daily products.

Choice Of Functional Masterbatch

There are some problems that we need to pay attention to when choosing functional masterbatch, these problems, usually we will ignore the problem, for these problems, functional masterbatch manufacturers for your sake, to give you a summary of some knowledge, I hope you can learn to these knowledge.

Functional masterbatches are also commonly used as a kind of masterbatch for functional dyeing, also in the selection and other masterbatches are not quite the same, specifically in what place? The following is a detailed introduction to these issues.

Different functional masterbatches have different performance when choosing pigments, so here is how to choose pigments for functional masterbatches.

The basic requirement for the pigments selected for heat resistant functional masterbatches is to withstand the temperature during the production of polypropylene fiber and to keep its performance stable. The temperature resistance is generally 270~280℃ or more.

The dispersion of the pigment used in the functional masterbatch should be excellent and evenly dispersed in the functional masterbatch, and the dispersant used will not reduce the quality of polypropylene fiber. Otherwise, it can't produce good quality raw liquid coloring fiber, and the operation is not stable, and it is easy to break or produce abnormal fiber when drawing fiber.

Brightness polypropylene raw liquid coloring has a variety of uses, including for bedspread base cloth and knitted fabrics, requiring bright shades. Because organic pigment is brighter and more vivid, and easy to color, so all use in the above uses need to use organic pigment.

The light resistance of the pigment is basically related to its chemical structure, so we should pay full attention to the light resistance of the pigment when making the functional masterbatch, and when the light resistant pigment needs to be used, we can consider adding UV absorbers.

Stability The pigments used in the functional masterbatches should have excellent stability to the colored polypropylene fiber. It means that the pigment will not react with the fiber when the colored fiber polymer is exposed to heat, light or high temperature for a long time, and new chemical groups will be formed to make the polymer performance rebound.
