Solid-State Polycondensation (SSP) Unit

Batch Solid-State Polycondensation (SSP) Unit
Designed for Efficient Viscosity Enhancement of Diverse Polymer Chips
Suitable for PET (Virgin/Recycled), PA6, PA66, PTT, PBT, PPS, PLA, PP, PE, and other polymer chips
Key Advantages
- Flexible Configuration
- Single-vessel integrated process (crystallization + reaction), reducing initial investment and footprint with quick material switching.
- Optional external pre-crystallization system shortens cycle time, boosting capacity by over 20%.
- Energy Efficiency & Eco-Friendliness
- Nitrogen-free operation throughout SSP process, lowering operational costs.
- Zero chemical additives/solvents, aligning with green manufacturing standards.
- Intelligent Control
- PLC/DCS automation for precise parameter management.
