ADDITIVE MASTERBATCH-Additive masterbatch is a specialized type of masterbatch that incorporates various additives into a polymer base to enhance or modify the properties of plastic products. Unlike color masterbatch, which is primarily used to add color, additive masterbatch focuses on improving functionality, performance, or processing characteristics.

Additive masterbatches may, for example, contain the following additives:

· UV stabiliser
· Antioxidants
· Lubricants and demoulding agents
· Foaming agents
· Antistatic agents
· Nucleating agents
· Anti -blocking agents
· Diffusers
· Laser-marking additives
· IR absorbers for laser welding of plastics
· Mattifying agents
· Metal and copper deactivators
