How to buy white masterbatch?

Odor: Some film manufacturers will smell a strange odor after using white masterbatch This is absolutely not allowed in milk film and food contact film. This is mainly due to the organic treatment of titanium dioxide in color masterbatches. In the process, if the coating assistant used is not appropriate or the amount is too large, or the dispersant used in the production process of the masterbatch has problems, the white masterbatch grade can be replaced.

Whiteness: The whiteness of white masterbatch is mainly represented by the titanium dioxide in the color masterbatch, and there are many factors that affect the whiteness of titanium dioxide, including the size, shape and particle size distribution of titanium dioxide particles, the types and content of impurities, and titanium dioxide. Particle lattice defects. Generally speaking, the chlorination method has better whiteness than the sulfuric acid method because the purity of the raw material titanium dioxide is higher and the impurities are less in the preparation process.

Hiding power: Hiding power is also an important indicator of white masterbatch. Good hiding power means that the pigment has strong tinting power. The required effect can be obtained with a small amount of addition. The hiding power of white masterbatch depends on titanium Selection and processing technology of white powder. Compared with anatase titanium dioxide, rutile titanium dioxide has a smaller and tighter unit lattice and a larger refractive index, so its hiding power and UV resistance are significantly better than sharp Titanium.

Flowability: The flowability of white masterbatch can be expressed as high melt index value, good flowability, good flowability means good processing performance, low machine torque, and low power consumption. When users choose white masterbatch, in addition to The masterbatch has good fluidity, and it should also be noted that the melting point of the masterbatch must be compatible with the carrier resin in its own factory products. The general principle is that the MI of the masterbatch is higher than that of the carrier resin.

Jiangsu Hongmei Masterbatch Co., Ltd. was established in 2003. The company is located in Changzhou National High-tech Development Zone. It is an earlier enterprise engaged in the research and development, production, sales and service of plastic masterbatches in China.

After more than ten years of steady development, the company is currently one of the larger polyolefin masterbatch manufacturers in East China, and its business scale ranks among the top domestic counterparts.
