1, masterbatch stored for a period of time after will absorb moisture, especially PET, ABS, PA, PC, and other, so to according to the true nature of grain in the same process of drying and reach the requirement for the moisture content.

2, with the desired Color Masterbatch color must be very careful, changes often occur and light color.

3, color and other additives will have a reaction, use caution.

4, the dilution ratio of 1: General masterbatch (20-100). The use of high dilution ratio, the production cost is low, but limited by the processing equipment, the general piston type of accommodation for 1:10, screw type injection molding machine for 1:20. Extrusion in the process of dilution ratio L / D and relevant, high L / D optional high dilution ratio, when the L/D=16:1, choose more than 1:20, for mixed refining excellent screw, even up to 1:100 dilution.
