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
If you want to increase the viscosity of recycled PET without cooling and reheating the material, a liquid-state polymerization installation raises the molecular weight directly in the molten phase. The process takes low-viscosity PET (flakes, sheet, fiber, or low-IV pellets) and delivers high-quality material for fiber, packaging strapping, pellets, and…
If you want to increase the viscosity of recycled PET without cooling and reheating the material, a liquid-state polymerization installation raises the molecular weight directly in the molten phase. The process takes low-viscosity PET (flakes, sheet, fiber, or low-IV pellets) and delivers high-quality material for fiber, packaging strapping, pellets, and sheet, much faster than the solid-state option. Unlike SSP, liquid-state polymerization works with the polymer already molten, so it completely eliminates the cooling step and the reheating step. The reaction in the molten phase is considerably faster than in the solid phase, which translates into lower energy consumption and a…
