Silicone Masterbatch is ultra-high molecular weight polysiloxane dispersed in polyethylene. Due to its particle form, it is easy to be added in the production process with better dispersion. are usually added directly to the polymeric raw materials during the processing of thermoplastics.

The role of silicone masterbatch can be different according to the different amount of addition; they can be used as flow accelerator, synergistic flame retardant, processing aid, hydrophobic agent, release agent, etc…
