Master Batch


Master Batch Introduction

Masterbatch are pelletized raw materials that provides a convenient way of combing critical EVA and rubber ingredients, such as additives, dispersants, vulcanizers and foaming agents.
Buwon’s masterbatch is used to manufacture midsoles, unitsoles and outsoles.


For Phylon midsole: EVA
For Rubber Outsole: Rubber



Reinforcing agent: ZnO,TiO2,CaCO3
Accelerator: M, DM, TS
Blowing agent
Other agent

Master batch(PBPD)
(Pellet type)


Buwon Master Batch

Buwon produces Master Batch products with various functions for EVA, rubber, and is able to develop Master Batch according to customer requirement properties.

Buwon Master Batch production capacity and advantages

Vietnam factory
– 1,850 MT per month

Indonesia factory capacity

– 450MT per month
– 3 Phases of gradual increase in total (Maximum 1,050MT per month)

* Buwon’s masterbatch offers advantages as the materials are pre- blended and pre-dispersed, leading to a higher quality production with less defects compared to using powders and liquids.

* Masterbatch offers safer handling and dust reduction for workers as well as easier storage.
