The same non-woven masterbatch, resin formula, different products why the color shades are different?

This is often the reason for injection molding machines. For the manufacture of injection molding machines, the use of different times or different maintenance conditions, resulting in poor mechanical conditions, especially near the degree of heating elements and differences in the barrel, the dispersion of the masterbatch in the barrel is not the same, this phenomenon Will appear.

According to the indication of the use rate of the non-woven masterbatch, the color is too dark (light)

Although this problem is very simple, there are many possibilities: 1. There is no serious test masterbatch pigment, there are more or less. 2. The use of measurement is inaccurate, when domestic enterprises, especially SMEs, have random measurements. 3. Masterbatch, resin matching problems, this may be improper choice of carrier masterbatch, it may be that the manufacturer changes the resin type 4 machine temperature is normal, especially on the high pressure side, the masterbatch stays in the machine for too long.

Treatment procedure: first check whether the color match with the resin type, measure accurately, then adjust the temperature and speed of the machine, if the problem still exists, masterbatch manufacturing

"Another brand of resin, and the same formula with non-woven masterbatch, change the color, which is why?

The density and melt index of different grades of resin will be different, so the nature of the resin is different, there is a difference between compatible masterbatch, which changes its color, in general, as long as the difference in density and melt index, so The color difference will not be too large, you can adjust the color masterbatch color.
