    LSPLINE® PET IV-increase Solution

    LSPLINE® improve the quality of PET recycling material (fibre, bottle flake, film, Low IV polymer) , To produce high grade PET fibre, PET packaging strip, PET pellet, PET film, Recycle bottle to bottle, fibre to fibre, improve the recycling utilization and quality of resources.

    LSPLINE benifits

    • Innovation structure

    The innovative structural design of the reactor, increases the reaction area of  polymerization, improves the fluidity of PET melt, makes the reaction time shorter.

    • Smart Control

    With our new smart control system, operations and real-time monitoring is more convenient than ever before, to predict maintenance and improve production efficiency.

    • High Energy Efficiency

    Frequency conversion equipment is used to automatically adjust operation frequency. The multiple level temperature control system minimizes the required heating energy consumption and reduces the operation cost of the whole system.

    LSPLINE® Excellent IV improvement effect

    With our good homogenization feature, the reactor could mix different raw materials into homogeneous melt.

    LSPLINE materials

    LSPLINE® Achieve Higher Throughput

    Through the buffer of our reactor, the whole production system is more controllable, increase output and avoid time lost during the process of replacing filters.

    LSPLINE higher thoughput

    LSPLINE® Working Principle

    LSPLINE® is an extremely efficient alternative to a Solid State Polymerization (SSP) as there is no energy needed to cool the polymer down and then reheat it. Further, the reaction time in the melt phase is considerably faster than in the solid phase, which also contributes to the better economics of the LSPLINE™ system.

    LSPLINE process

    • Homogenization

    Because the source of recycled material is complex, the components are difficult to guarantee, which shows that the fluctuations of melt in production process. In order to stabilize the IV, the reactor runs at a certain speed, so that the internal melt is fully mixed.

    • Remove Impurity

    Because PET re-polymerization is carried out in a high vacuum state, the low molecular material contained in the raw material and the auxiliaries will be vaporized in 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. the polymerization still occur under certain temperature and vacuum state, The molecular chain and IV will increase.

    LSPLINE® Multiple Filter System

    LSPLINE multiple filter

    1. After Extrusion

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

    1. During Reaction

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

    1. After Reaction

    High-viscosity melt passes through the last melt filter and the inorganic impurities

    that still remain in the melt will be filtered.

    LSPLINE® High Quality Products

    LSPLINE high quality output

    • 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.

    LSPLINE® Reactor Innovation

    LSPLINE 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.
