SUNKAIER products used in the biodegradable polyester rubber project

SUNKAIER provides specialized chemical process equipment and technology used in the production and compounding of biodegradable polymers. In the context of biodegradable polyester and rubber projects, their products are primarily utilized for reactive polymerization and high-viscosity mixing. Key SUNKAIER products used in these processes include: Extruding Kneaders (SK3000S-REX Series): These are used for materials requiring chemical reactions during the extrusion process. They are specifically suitable for reactive polymerization of polymers like TPU and Spandex, which share processing characteristics with biodegradable polyester rubbers. Reactive Extrusion Process Plants: These modular systems are designed to bond individual components via chemical reactions, offering superior product handling and mixing properties for the synthesis of advanced polymers. High-Viscosity Kneaders (SK3000E-Eblades): Featuring an E-impeller design, these units optimize the mixing of high-viscosity materials. They provide the enhanced shear and dispersion necessary for processing biodegradable resins and rubber compounds where uniform thermal control is critical. Chemical Reactors and Modular Units: SUNKAIER designs and manufactures specialized chemical reactors and modular process units that facilitate the development and transfer of process technologies for biodegradable specialties.

Key Features for Polymerization & Devolatilization

• E-Impeller Blade Design: Optimizes the mixing and kneading of high-viscosity materials by providing enhanced shear and dispersion, critical for uniform polymer chains.
• Large Free Vapor Volume: Facilitates the efficient release and removal of volatiles, gases, and residual solvents during the devolatilization phase.
• High Surface Renewal Efficiency: Promotes frequent renewal of the material's surface area, which accelerates chemical reactions and enhances heat transfer for faster processing.
• Effective Self-Cleaning: Minimizes dead zones and product accumulation, preventing material degradation—essential for maintaining the integrity of biodegradable polyesters.
• Advanced Thermal Control: Features large heat transfer areas for precise temperature management, ensuring uniform heating or cooling of sticky, viscous products. 

Benefits for Biodegradable Polyester Rubber Projects

• Improved Product Homogenization: Superior kneading capabilities ensure a consistent blend, which is vital for the mechanical properties of biodegradable rubber.
• Process Intensification: Combines multiple steps—such as chemical synthesis, evaporation, and devolatilization—into a single continuous or batch process.
• Post-Polymerization Utility: Specifically used for polymer gel crushing and washing to break down large gel pieces and remove impurities.
• Scalability and Reliability: Offers reliable process scale-up from pilot to industrial units, ensuring large production capacities with high process yields per unit volume.
• Economic Efficiency: Designed for a short return on investment through reduced energy consumption and high monomer yields.
