What is silicone color masterbatch？
Color masterbatch, also known as color seed, is a new type of special colorant for polymer materials, also known as pigment preparation,
which is composed of three basic elements: pigment or dye, carrier and additive. Simply put, a color masterbatch is an aggregate made of an evenly loaded ultra-constant pigment or dye.
What is the basic composition of silicone masterbatch?
Silicone masterbatch
1. Pigment
Pigments are divided into organic pigments and inorganic pigments.
Common organic pigments include phthalocyanine red, phthalocyanine blue, phthalocyanine green, light fast red, polymer yellow, purple, azo red, etc.
Common inorganic pigments are: cadmium red, cadmium yellow, titanium dioxide, carbon black, iron oxide red, iron oxide yellow, etc.
2. Carrier
The carrier is the matrix of the color masterbatch. The same resin is generally used as the carrier for the special color masterbatch.
The compatibility between the two is better, but the fluidity of the carrier must also be considered.
3. Dispersant
The melting point of the dispersant should be lower than the melting point of the resin, have good compatibility with the resin,
and have good affinity with the pigment. The most commonly used dispersants are polyethylene, low molecular wax and stearate.
4. Additives
Such as flame retardant, whitening agent, antibacterial, antistatic, antioxidant and other varieties, unless required by customers,
color masterbatch generally does not contain the above additives.
