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 transparency, luster, dispersion, brightness and sense of touch of the end products
