Silicone Masterbatch – High Performance Processing Aid for Plastic Manufacturing

2026 08/11

Silicone masterbatch is a functional concentrate made by dispersing ultra-high molecular weight polydimethylsiloxane into a carrier resin at concentrations ranging from 20% to 70%. It is designed to improve processing efficiency and surface properties of plastic products. This masterbatch provides excellent internal lubrication, reduces friction between polymer chains, and enhances melt flow during extrusion and injection molding.

Key Benefits

  • Reduces coefficient of friction on finished surfaces

  • Improves mold release and reduces ejection force

  • Enhances scratch resistance and surface smoothness

  • Prevents melt fracture and reduces die drool

  • Non-migrating and non-blooming – no surface residue

Material Compatibility
Our silicone masterbatch is available in various carrier resins to match different base polymers, including PE, PP, ABS, PA, PC, PVC, PET, and more. The carrier is selected to ensure good compatibility and even dispersion, minimizing any negative impact on mechanical properties or appearance.

Applications

  • Film and sheet extrusion

  • Injection molded parts

  • Blow molding

  • Wire and cable insulation

  • Pipe and profile extrusion

  • Artificial turf yarn and synthetic fibers

Processing Advantages
Adding silicone masterbatch during processing reduces extruder torque, lowers melt temperature, and increases output rates. It also helps eliminate melt fracture and reduces die buildup, leading to longer production runs and less downtime for cleaning.

Customization Options
We offer customization of carrier resin type, silicone content (20%–70%), processing method suitability, and special performance requirements such as food contact grade or medical grade. Tell us your base resin and target performance, and we will tailor the formulation accordingly.
