Innovative structure

The innovative reactor structure design increases the polymerization reaction area and improves the flowability of the PET melt, resulting in shorter reaction times.

Intelligent control

With our new intelligent control system, operation and real-time monitoring is easier than ever, allowing for predictive maintenance and increased production efficiency.

High energy efficiency

Frequency conversion equipment is used to automatically adjust the operating frequency. The multi-stage temperature control system minimizes the required heating energy consumption and reduces the operating costs of the entire system.

LSP excellent IV improvement effect

With our good homogenization characteristics, the reactor can mix different raw materials into a homogeneous melt.

LSP enables higher throughput

Through the buffer of our reactor, the whole production system is more controllable, and the output is increased to avoid wasting time in the process of filter replacement.

Working principle of LSP

LSP is an extremely effective alternative to solid state polymerization (SSP) because it does not require energy to cool the polymer and then heat it. In addition, the reaction time of the melt phase is much faster than that of the solid phase, which also helps to improve LSPLINE ™ Economy of the system.

Homogenization

Due to the complex source of recycled materials, it is difficult to ensure the composition, which shows the fluctuation of the melt in the production process. In order to stabilize IV, the reactor runs at a certain speed to fully mix the internal melt.

Remove impurities

Since PET is re polymerized under high vacuum, low molecular substances contained in raw materials and additives will be vaporized under high temperature.

Molecular chain growth

There are still a large number of hydroxyl and carboxyl molecules in the raw materials, and the catalytic system is still effective. Polymerization will still occur under certain temperature and vacuum conditions, and the molecular chain and IV will increase.

LSP MULTIPLE FILTER SYSTEM

AFTER EXTRUSION

The first melt filter after the extrusion can filter the inorganic impurities, and facilitate the further reaction.

DURING REACTION

Under high vacuum conditions, the oligomers and decomposed gases are separated from the melt and removed into the vacuum system.

AFTER REACTION

High-viscosity melt passes through the last melt filter and the inorganic impurities that still remain in the melt will be filtered.

LSP HIGH QUALITY PRODUCTS

HIGH PURITY

After multiple filtration and homogenization, the recycled polyester melt has higher purity and IV, and color of the end product are more uniform.

HIGH STRENGTH

Under the high temperature and vacuum polymerization reaction, the molecular chains and IV are continuously increased, and the strength of the produced polyester product is also better.

LSP REACTOR INNOVATION

NON-SHAFT DESIGN

The unique shaftless design makes the melt filming reaction smoother, avoiding the risk of material accumulation.

LARGER REACTION AREA

The larger reaction area has better decontamination efficiency, better IV-increase effect, and achieve higher purity after reaction.

SHORTER REACTION TIME

Innovative mesh design allows smoother melt flow, which makes the liquid level control more stable and can be controlled at a very low level, allowing the melt reaction time to be shortened and the end product color to be better.
