• Color Masterbatch And Compounding for Thermoplastic Elastomers (TPE)

  Thermoplastic elastomers (TPEs) are naturally colorless and can be colored using pigments or dyes through pre-coloring or in-process coloring methods. In-process coloring, often performed with twin-screw extruders, allows pigments to disperse evenly during melting without adding extra thermal stress. The most common approach is using color masterbatch, which combines pigments with compatible carrier resins such as PP, PE, PS, or EVA to ensure uniform color and good material performance. Proper carrier selection, dilution ratio, and process optimization help achieve consistent, high-quality colored TPE pellets for various molding and extrusion applications.

• Differences And Similarities in Equipment for TPE, TPR, Silicone, TPU, And TPV Pelletizing

  This article compares extrusion and pelletizing equipment used for TPE, TPR, TPU, TPV, and silicone rubber materials. While all elastomer pelletizing lines share core components—such as twin-screw or single-screw extruders, cooling systems, and pelletizers—each material has specific equipment needs. TPU requires precise temperature and moisture control, TPV demands high-torque twin-screw extruders for dynamic vulcanization, and silicone uses specialized extruders with vacuum degassing and curing systems. Overall, process optimization and tailored screw configurations are key to achieving high-quality pellets and efficient production.
