High-Performance Thermoplastic Elastomer (SEBS+EVA) Compounding & Pelletizing Line

This project is designed to address the challenges of dispersion and plasticization during the blending of SEBS (Styrenic Thermoplastic Elastomer) and EVA (Ethylene Vinyl Acetate).

The production line utilizes our advanced SAT65 Series Co-rotating Parallel Twin Screw Extruder, integrated with a high-efficiency Water Ring Pelletizing System.

Specifically engineered for high-viscosity and heat-sensitive elastomer materials, this solution ensures uniform particle performance and excellent pellet appearance, achieving stable mass production of high-quality modified elastomers.

1. Equipment Model

   SAT65-48 Twin Screw Water Ring Pelletizing Line

2. Core Power

   AC 160KW high-torque drive motor, providing powerful shear force to accommodate the conveying of high-viscosity elastomer melts.

3. Screw Speed

   600 rpm high-speed operation, significantly enhancing mixing efficiency and production throughput.

4. L/D Ratio

   48:1 large length-to-diameter ratio. The extended processing section provides ample residence time and reaction space for the complex SEBS+EVA system, ensuring full microscopic fusion of the two polymer phases and greatly improving mechanical properties.

5. Pelletizing Method

   Water Ring Pelletizing. Addressing the sticky nature and difficult cooling characteristics of elastomers, the water ring system offers a gentle and efficient cooling path. This effectively eliminates die-face sticking and agglomeration issues, ensuring round and uniform final pellets.

The modified materials produced by this line are primarily used in:

1. High-end Foaming Shoe Materials

   Leveraging the high resilience of SEBS and the lightweight properties of EVA.

2. Soft-Touch Overmolding

   Widely used in tool handles, protective cases for electronics, etc.

3. Impact Modifiers

   Serving as toughening agents for engineering plastics.
