Why colored flame retardant ABS tends to have large color differences

ABS material has always been the first choice material for home appliance casings, automobile parts, etc. due to its superior comprehensive properties, including superior rigidity, toughness, chemical resistance, and processability, as well as lower density and price. For safety performance and aesthetics, many exterior parts will choose colored flame-retardant ABS materials. However, Plastic has also received feedback from some customers that flame-retardant ABS is prone to color differences. Mattel Plastic uses 17 years of experience in customizing flame-retardant materials to summarize the possible reasons for you as follows:

1. Flame retardant decomposition: Flame-retardant ABS mostly uses brominated flame retardants, which are not resistant to high temperatures. If the temperature is too high during processing or drying, the problem of flame retardant decomposition may occur, and the processing process will be unstable and easy to Color instability occurs;

2. High density of color masterbatch and sedimentation: Some injection molding manufacturers will choose natural color material + color masterbatch for production. Because the color masterbatch is added with more powder, the density is higher than that of flame-retardant ABS. When mixing, the color masterbatch may precipitate to the bottom of the barrel, causing Product color is uneven;

3. There is color difference between batches of the material itself: The color matching of flame-retardant modified materials is indeed more difficult than that of raw materials. It cannot be ruled out that flame-retardant ABS produced by some manufacturers has large color differences between batches;

4. Addition of recycled materials: Many manufacturers will add recycled materials or materials to the raw materials to reuse the crushed materials. The color of these reused materials is unstable, which will affect the overall color.
