  The main factors affecting the dispersion of talc in plastic raw materials are formulation, temperature, yield and process flow。In addition, when the amount of talc is large, the method of gradually adding talc can be used to obtain a good dispersion effect。

  3, for different plastics, should choose different specifications of talc。This is very special。If you don't make good choices, it can backfire。Because different plastics, different products and different conditions of use have different requirements for raw materials, different choices must be made to achieve the desired effect。
