There are two types: organic dispersant and inorganic dispersant.
The high-grade black masterbatch uses organic dispersant, which is mainly used for plastic products with high environmental requirements, such as drip irrigation products.
Low-grade black masterbatch uses inorganic dispersant, commonly calcium carbonate. The use of inorganic dispersants can greatly reduce the cost of black masterbatch, but the fatal thing is that calcium carbonate can accelerate the aging of plastic products.
