Pigment yellow 183 has excellent heat stability. In the process of coloring high-density polyethylene (HDPE) with 1/3 standard depth, its thermal stability can reach 300 ° C, and it does not cause dimensional deformation. , Suitable for coloring of plastics (such as engineering plastics ABS, HDPE, etc.) that require processing at higher temperatures.

Product Usage:
In recent years, red-yellow-yellow lake-based pigments that have been put on the market for plastics have excellent heat resistance and stability despite their slightly lower tinting power. In the high-density polyethylene (HDPE) coloring process of 1/3 standard depth, Stability can reach 300 ° C, and there is no dimensional deformation, and light fastness is 7-8 grades. It is suitable for coloring of plastics (such as engineering plastics ABS, HDPE, etc.) that require processing at higher temperatures.
Synthesis principle:
From the diazo component 2-amino-4,5-dichlorobenzenesulfonic acid, an aqueous solution of yellow nitrite was added according to a conventional method to carry out a diazotization reaction, and excess nitrous acid was removed with ammoniasulfonic acid; 3'-sulfonic acid phenyl) -3-methyl-5-pyrazolinone, which is coupled in a weakly acidic medium (pH = 5-6), and then reacts with calcium chloride to transform into a calcium salt lake, Heat, filter, wash and dry.
