Masterbatch is usually used along with the manufacturing process of  plastic products, such as injection moulding, blow moulding and extrusion. Masterbatch virtually serves three complementary functions:

1. Reduce the cost of making the end product by partially filling the gap of some expensive raw materials.

2. Add an desire feature or properity, such as fragrance and fire-retardance to enchance the end product performance.

3.  Improve the tranparency, luster, dipsersion, brightness and sense of touch of the end products
