Application Of Extrusion Grade TPU Granules
Sport Footwear Components
TPU is tough and can withstand high impacts. TPU might be used for the sole or toe box of sport shoes. TPU toe caps protect the toes from injury in sports. TPU can also be used in shock-absorbing midsoles and ergonomic shoe soles.
Electronic Device Cases
TPU extrusion can produce cases for smartphones, tablets, and MP3 players. The cases are lightweight, transparent, and impact-resistant. TPU material can also provide protective covers for cameras.
Automotive Interior Parts
TPU can make door strips, dashboard materials, and other interior parts. Extrusion die can create three-dimensional parts for the auto interior. Such parts have high transparency and a good light guide effect.
Medical Device Covers
TPU extrusion can produce covers for medical devices like pumps and ventilators. The covers protect the devices from dust and moisture. They are transparent so that operators can monitor the device's function.
Flexible LED Light Strips
TPU can produce flexible light strips for home use or auto decoration. The light strip is waterproof and can bend in any shape. Users can use it to decorate furniture or the interior of a car.
Protective Sleeves And Cable Management Solutions
TPU extrusion can produce cable sleeves and guards. The cables are safe from abrasion and chemical damage. They are flexible enough to allow easy routing and organization.
TPU Sheets
TPU-based films offer unequalled performance for a great variety of end products. Among the most common applicable fields for Thermoplastic Polyurethane films are: inflatables, textile coatings, garment, adhesiveand barrier films.
TPU Extrusion Process
Material Preparation
Drying: TPU pellets are usually supplied in pellet form and must be dried to remove any moisture, as this can affect material properties.
Material Feeding: Dried pellets are fed into the hopper of the extruder and then transported to the feeder barrel where they are melted and mixed.
Extrusion Process
Melting: Inside the extruder barrel, the pellets are heated and compacted, transforming into a molten state.
Shaping: The molten TPU is then forced through a die, which shapes it into the desired profile.
Cooling and Solidification: The extruded material is cooled and solidified to form the final product. Effective cooling is crucial, especially for TPU with low melt strength.
Key Considerations for TPU Extrusion
Temperature Control: The temperature in each area of the extrusion production line must be precisely controlled to ensure proper plasticization and melting of the material, while also preventing material degradation caused by overheating.
Extrusion Speed: The extrusion speed influences the degree of plasticization and the shape of the product. It needs to be adjusted based on the material properties and mold design.
Mold Selection: The choice of mold directly affects the shape, size, and performance of the product. It is crucial to select the appropriate mold according to product requirements.
Cooling Time: The product must have sufficient time in the cooling section to solidify, maintain its shape, and reduce temperature, thereby preventing deformation and cracking.
Processing Environment: The extrusion production line must be kept clean to prevent impurities and dust from entering, which could negatively impact the quality and performance of the products.
