Today to explain to you, what are the original formula of polypropylene color master, and the basic use of Polypropylene masterbatch.

Polypropylene masterbatch This series of products has the following advantages:

1) The pigment particle size in the natural masterbatch product is less than 1μm;

2) Uniform and stable dispersion, high coloring power;

3) Excellent filtration performance;

4) High heat resistance, light resistance.

Polypropylene masterbatchs Polypropylene fibers with various colors are caused by the uniform dispersion of pigment particles in the polypropylene fiber. The key is that the pigment particles are sufficiently refined and evenly distributed (mixed) in the polypropylene fiber. Fine dispersion is the process by which pigment particles are sufficiently refined and evenly distributed (mixed) in polypropylene fibers. Refining and dispersing is to break the pigment agglomerate or aggregate to the smallest particle, and the key is uniform dispersion, dispersion effect on the color, transparency, luster, fiber strength, elongation, aging resistance, electric negative rate of colored polypropylene fiber are affected.

Generally speaking, only when the particle size of pigment dispersing is less than 1um can it be used for fiber or ultrathin film, while when the particle size is greater than 5um, the surface of the fiber will be dull, and when the particle size is greater than 10um, the surface of the fiber will produce spots and streaks, and the breaking strength and elongation of the fiber will decrease with the increase of the particle size. The smaller the particle size, the stronger the coloring power and the better the dispersion. At the same time, the smaller the particle size makes the surface increase, leading to the increase of the hiding power.

Because the pigment particle state has three kinds: primary particle, agglomerate and agglomerate, and the general commodity pigment particle is larger than the aggregate particle (about 75-250um), so it must be dispersed. The so-called dispersion of pigment is the process of crushing and refining the aggregate.

Pigment dispersion, first is to use wet paint, wetting agent is coated on the surface paint, cohesion between the pigment to reduce, reduce the energy for the broken pigment aggregate, followed by the crushing of pigment, lead free movement between the pigment particles (impact stress) and pigment aggregate by shear stress to the surrounding media will aggregate particle breakage. Paint after scattered refinement, size, surface area increases, the paint surface free energy will increase instability caused a refinement of the pigment, so in the paint surface should further coating processing, can reduce the formation of new interface surface, prevent condensation, then the pigment in the melt mixing dispersion, the wetting and smash the paint evenly dispersed distribution to coloring material.

Polypropylene masterbatch of fine material selection, good physical properties, bright and stable color, widely used in non-woven fabric, carpet, filament, staple fiber, coarse denier and other products coloring. According to the customer's different color, single wire size, wire shape, temperature resistance, light resistance and other performance requirements, to provide customers with personalized services.
