The advantage of the antistatic agent-filled product is that the coloring of the product is not limited, and the low molecular type antistatic agent has little effect on the product performance, and the surface resistivity thereof is 1010-1013 Ω. However, the electrical properties of low molecular antistatic agent-filled products are gradually lost over time.
The main development trend in foreign countries is to develop and produce polymer antistatic agents. Polymer antistatic agents can also be called long-term antistatic agents. It will not be washed like water or after long-term use like low molecular antistatic agents. It loses its conductivity. The main types of polymer antistatic agents are: polyether type, quaternary ammonium salt type, sulfonic acid type, acid graft copolymer, ionic type. The main manufacturers include Japan's Sanyo Chemical, Sumitomo Elite, Sumitomo Science and Industrial, Industrial Pharmaceuticals, Ciba Refinery in Switzerland, Clariant, Wyco in the United States, and Great Lakes. The amount of the polymer type antistatic agent is 5-15 times that of the low molecular type antistatic agent, and the compatibility with the resin is also considered to select a suitable compatibilizer, which is subject to cost constraints. Certain restrictions. At present, domestic low-molecular antistatic agents are mainly used. Representative manufacturers include Hangzhou Plastics Research Institute and Beijing Research Institute of Chemical Industry.
