Sunkaier - Reactive Extrusion Process Plant
Reactive extrusion is a special process in extrusion technology in which individual components are bonded by a chemical reaction. Extrusion systems from XNEADER are particularly suitable for the reactive extrusion process due to the excellent product handling and mixing properties.
Plastic compounding is a process of melt blending plastics with other additives. Many additives can be used during the extrusion process to enhance processing characteristics of the polymer or to alter product properties. Such additives include lubricants, thermal stabilizers, antioxidants, radiopacifying agents, and colorants. The final product is called a compound or composite. During the compounding process heat is important as well the mixing capabilities, for this reason co-extruders or Twin-Screw Extruders are the most suitable in plastic compounding. Compounding is also used in the recycling process using scrap feedstock material that can be added into the process of compounding for compounding and regranulation purposes of recovered plastic materials.
Plastics compounding involves an intricate process with multiple stages. These may include determining additives ratio, high-speed mixing via a Bausano twin-screw extruder, melt mixing, and cooling, all before final pellet cutting and packaging. Generally, a range of different materials can be used, especially with XNEADER Extruders. Most common materials include:
- Polypropylene
- Polyvinyl chloride
- Polystyrene
- Expanded polystyrene
- Polyethylene terephthalate
- Polyurethane
- Acrylonitrile butadiene styrene (ABS)
- Nylon
Our dies are designed, engineered and built in house so we can provide a solution to any customer requirement in terms of product shape
A High-Quality product from any raw materialThanks to our ability to customize the extruder’s modular screw configuration along with our technicians’ experience, we can adapt the line characteristics based on the raw materials selected and thus provide a high-quality product.
Durability and ease of maintenance
Our in-depth knowledge of the processes (use of multi-blade cutters) and use of top-quality construction materials (dies made of high tensile steel) allow us to guarantee a long life and operability of the processing lines.
