Problems solved by technology

[0004] The processing temperature of polyphenylene sulfone materials is between 350 and 380 ° C. It is difficult for traditional organic dye molecules to maintain good thermal stability at this temperature, and the migration resistance of dyes is usually poor, which will lead to the dyeing process. The color fastness of polyphenylene sulfone products is low
On the other hand, there is a large interface difference between the inorganic pigment and the resin matrix, and it is difficult to achieve its uniform dispersion in the resin, resulting in problems such as uneven coloring of the resin and a decrease in apparent performance, and the use of a large number of dispersants is also difficult. will lead to a decrease in the mechanical properties of the material
