Main Technical Parameter

Product Description

The Eco-friendly Grafting & Chain Extension Pelletizing Series is a specialized reactive extrusion system designed for complex chemical modifications of polymers. This series is engineered to facilitate high-precision grafting and chain extension reactions, making it an essential tool for the production of functionalized resins and high-viscosity bioplastics.

Precision Reactive Extrusion Technology: This line is highly effective for critical industrial applications, including PE grafting for the cable and pipeline industries, and the production of MAH-grafted PE, PP, EVA, and POE used as high-performance compatibilizers. Furthermore, it is optimized for the chain extension of PET, PLA, and PBAT, significantly enhancing melt viscosity for improved structural performance. The co-rotating twin-screw architecture provides the intensive shearing force necessary to ensure that monomers, initiators, and base resins are mixed with extreme uniformity, leading to higher grafting rates and more stable chemical distribution.

Advanced Process Control and Purity: Flexibility is a core feature of this series, allowing operators to precisely adjust material residence time through modular screw configurations, variable rotating speeds, and controlled feeding rates. This adaptability ensures that the equipment can be fine-tuned to meet the specific reaction kinetics of various grafting processes. To ensure the highest quality output, the unit is equipped with an integrated vacuum devolatilization system. This system efficiently extracts unreacted monomers, small molecular by-products, and other volatiles, directly resulting in superior product stability and exceptional finished purity.

Scalable High-Yield Production: Designed for continuous industrial duty, the series offers a range of models capable of reaching throughputs up to 1,500 kg/h. With robust technical specifications and a 56 L/D ratio for extended reaction zones, these machines provide a reliable platform for high-yield chemical modification. Priced from USD 75,000 to USD 180,000, the series represents a technologically advanced and cost-effective investment for manufacturers in the functional polymer and recycling sectors.
