(1) The color masterbatch will absorb moisture after being stored for a period of time, especially PET, ABS, PA, PC, etc., so it must be dried according to the same process as the natural color pellet and meet the moisture content requirement.

(2) Use masterbatch to match colors to achieve the desired color and luster must be very cautious, color difference and shade changes often occur.

(3) There will be reactions between the masterbatch and other additives, so be careful when using it.

(4) Attention should be paid to the selection of the dilution ratio of masterbatch. If a high dilution ratio is selected, the production cost is lower, but it is also limited by processing equipment.
