LSP Liquid-State Polymerization System
Rapidly increases PET viscosity directly in the melt phase without a cooling and reheating cycle.
LSP Liquid-State Polymerization System

Technical specifications
Sustainability impact
Equipment engineered for long-lasting operation and built from recyclable materials, in line with the principles of the circular economy.
Key features
Fast melt-phase reaction
The process is considerably faster than solid-state polymerization.
No cooling and reheating
The material remains molten, reducing energy consumption and total processing time.
Axless cage reactor
The large reaction surface and axless design reduce buildup and simplify maintenance.
Product description
The liquid-state polymerization system increases PET molecular weight and viscosity directly in the melt phase. Removing the cooling and reheating cycle reduces energy consumption and shortens reaction time compared with solid-state polymerization. The axless cage-type LSP reactor provides a large film-forming surface, prevents material buildup and simplifies maintenance. The system…
The liquid-state polymerization system increases PET molecular weight and viscosity directly in the melt phase. Removing the cooling and reheating cycle reduces energy consumption and shortens reaction time compared with solid-state polymerization. The axless cage-type LSP reactor provides a large film-forming surface, prevents material buildup and simplifies maintenance. The system can process flakes, sheet, fiber, textiles, waste yarn and low-IV PET pellets.
