Main Applications of TPU Reaction Extrusion Granulation Lines

TPU (Thermoplastic Polyurethane) is widely used in various industries due to its excellent physical properties, chemical stability, and processability. The TPU Reaction Extrusion Granulation Line utilizes a one-step continuous reaction and extrusion granulation process to efficiently produce TPU granules with varying hardness and performance to meet diverse market demands. Key applications include:

Shoe Industry

Athletic shoes͏, outsoles, midsoles, air cushions͏, and heel components widely utilize TPU granules as they offer wear resistance and excellent elasticity including providing excellent anti-slip properties.

Cables an͏d Wires

They are used as high performance cable jackets, optical fiber jackets and industrial wires as they offer wear resistance, oil resistance, flam͏e retardancy including excellent flexibility.

Automotive Industry

Good for car seals, dash parts, inside trim, and noise stoppers they get a lot of use because they fight bad weather, oil, and shocks very well.

Medical Devices

TPU pellets find their application in catheters, medical films, breathable membranes, and surgical instrument components. It has a biocompatibility performance which is very good and safe.

Films and Sheets

Packaging films, sports equipment protective film, waterproof breathable film, decorative film-transparency, flexibility plus abrasion resistance-consume the variety.

Industrial Products

Hoses, conveyor belts, seals plus mechanical components-consume excellent wear plus oil as well as tear resistance-extend service life.

Advantages of the TPU Reactive Extrusion Pelletizing Line

Efficient and continuous production

Smooth and unbroken creation brings together raw stuff measuring, reacting, pushing out, and making into small pieces, cutting down on middle steps and boosting how fast things get made.

Steady product quality

On-the-spot reaction control plus exact heat and force management bring about even and steady TPU granules in toughness, clearness, and ability to withstand weather.

Formulations that can be freely changed

Toughness range (60A–85D), color, clearness, and function (ability to resist burning, fighting static, blocking UV rays) can be set based on what the buyer wants.

Low energy consumption and environmental friendliness

The reaction and pelletizing occur at the same time, thus saving energy and also avoiding carbon emissions which emanate from several heating steps in the traditional process.

High Degree of Automation

This uses a PLC control system with automatic feeding online monitoring and data acquisition making labor less intensive and adding more stability.

Wide adaptability

It may not just bring out general purpose TPU pellets but can be further widened up to the production of medical grade, food grade, and functional TPU products to fulfill varying market demands.
