Coloring plastics plastics industry is an indispensable part of their significance is landscaping products; second important purpose is to identify the effect, the effect achieved by the colored logo has practical value.Color Masterbatch
In addition, the colored plastic may also be given a variety of functions plastic, plastic such as increased light resistance, weather resistance, electrical conductivity and antistatic effect, and so on.color master batch formula

Dyes are soluble in most solvents and is dyed medium organic synthetic chemicals. It is characterized by transparency, high color strength, density. Mainly suitable for engineering plastics (ABS, HIPS, PET, nylon 6, etc.), since the dye molecules are generally small structures, such as for polyolefin coloring migrated happen.
pigment
Pigments are not soluble in common solvents colorant. In contrast with a dye, a pigment and a coloring material which is not desired affinity.Color Masterbatch

Through its pigment particles are dispersed in the material to be colored, leaving the material to produce color. Since the pigment has insolubility, so as to obtain the desired coloring properties, the pigment is required to mechanically disperse uniformly into the plastic, primarily PVC and polyolefins suitable for coloring plastics, some of which may also be used plastic colored varieties.

Inorganic pigments are generally metal oxides, sulfides and sulfates, chromates, molybdates, and salts, such as carbon black. This type of pigment is not soluble in common solvents and plastics, their thermal stability and light stability than the organic pigments are generally excellent.Color Masterbatch

In the plastic processing temperature range, with the exception of lead salt, chrome yellow and cadmium orange, other inorganic pigments are very stable, but its coloring power than the organic pigments difference. The relative density of larger inorganic pigment, typically 2.5-5.0.
