High Coloring Strength Of White Masterbatch
- Sep 12, 2017 -

White Masterbatch is widely used in the production of injection molding products, blown film plastic bags, as well as production flow film and so on. Because white Masterbatch titanium dioxide content is high, so the plastic products produced by high brightness, in the temperature resistance of its performance is also very good, White Masterbatch the raw material itself has no impact on the physical properties.

Therefore, in many colors of masterbatch, white Masterbatch has become the production of plastic products in the conventional color, the dosage is very large. Therefore, White Masterbatch in the development process of the production of white Masterbatch technology also requires more and higher. In particular, the higher the content of titanium dioxide, may result in the production of products dispersed uneven or mixed-color phenomenon.

White masterbatch application field: Injection molding, blow molding, drawing, Flow extension, extrusion, blown film, foam, sheet, pipe, pumping, hollow, EVA, blowing bottles, sheet, household appliances, toys, packaging materials, wire and cable, plastic bags, automobiles, building materials, White Masterbatch sports and leisure supplies, packaging bags, packaging bottles and other plastic products industry. Applicable to plastic raw materials PE, PO, PP, ABS, PVC and so on.

White masterbatch with bright color, colorful, high intensity of coloring, good dispersion, high concentration, good whiteness, hiding power, reasonable price and other advantages, White Masterbatch resistance to mobility and good heat resistance characteristics. Ensure product quality and yield, reduce energy consumption, improve production efficiency.

Considerations for White Masterbatch use

First, in order to reduce the color of the fiber chromatic aberration, to the white masterbatch to be diluted, control mixing ratio, filament not less than 3%~10%, short fiber not less than $number, monochrome continuous filament with three-color equipment, White Masterbatch white masterbatch must be mixed into the extruder, at the same time to increase the melt itself mixing ability, Mixing devices can also be added in the extruder segment.

Second, white Masterbatch mixed in the color of the formula to determine the colour, the white masterbatch before spinning evenly dispersed in the polypropylene section, is the key to ensure product quality, the specific mixing method there are two types. White Masterbatch The first is the heavy method and volume method, in the extruder or after the white masterbatch melting, with a small extruder into the polypropylene melt, the uniformity is very good.

Third, when choosing the white Masterbatch, to choose according to the range of selection, polypropylene Masterbatch has fine denier, coarse denier, coarse denier white masterbatch color can not be used for fine-denier color, color should be considered spinning fiber single denier, White Masterbatch select the same level of white masterbatch.

Four, the choice of white Masterbatch is the same manufacturer of the best products, in order to reduce the cost should be selected high concentration of white masterbatch. White Masterbatch White Masterbatch pigments have high, medium and low-grade points, color should be based on the quality requirements of the fiber, the appropriate choice of different levels of white masterbatch. To avoid the pigment light, different thermal stability caused by the quality of the product fiber variation, color should also be selected in line with the requirements of fiber quality, with the same light, thermal stability level of the white masterbatch color, White Masterbatch crude fiber than fine fibers need less concentration, its white masterbatch application ratio is proportional to the square root of the number of fiber denier.
