Applications : Ideal for the manufacture of bottles, containers and other hollow parts requiring flexibility and strength.
Extrusion
Extrusion involves forcing molten TPU through a die to create continuous shapes such as tubes, sheets, and profiles.
Applications : Suitable for manufacturing large quantities of uniform products including pipes, films and profiles.
Drying requirements : Ensure that the residual moisture content is ≤ 0.02% before processing.
Other treatment methods
Compounding : TPU can be compounded to create tough plastic moldings or processed using organic solvents to form laminated textiles, protective coatings, or functional adhesives.
3D Printing : TPU filaments are compatible with 3D printing techniques such as FDM (Fused Deposition Modeling) and SLS (Selective Laser Sintering), which allows the production of flexible parts with complex geometries.
TPU Changes
TPU can be modified to improve its properties and suitability for first dataset specific applications. These modifications include blending with other materials, adding various additives, and using different processing techniques.
TPU Blend with Polyether and Polyester : Combining TPU with polyether and polyester can enhance its properties for specific applications. Polyether-based TPU is known for its low-temperature flexibility and resistance to hydrolysis, making it suitable for moisture-rich environments. Polyester-based TPU offers superior resistance to oils and hydrocarbons, making it ideal for applications requiring chemical resistance.
Polycarbonate Diols (PCD) : PCDs produce TPUs with superior performance characteristics including extreme durability, higher chemical resistance, improved hydrolytic stability, greater thermal resistance, improved abrasion resistance, and superior mechanical properties.
Additives
Reinforced TPU : When blended with glass or mineral fillers/fibers, TPU becomes a structural engineering polymer with improved abrasion resistance, high impact strength, good fuel resistance and high flow characteristics.
UV Stabilizers and Antioxidants : These additives protect TPU from degradation due to UV exposure and oxidation, extending the life of products used outdoors or in high temperature environments.
Flame Retardants : The addition of flame retardants to TPU improves its fire resistance, making it suitable for cable jackets and other applications where flame resistance is crucial.

TPU Part Design for SLS Manufacturing
Selective laser sintering (SLS) is an additive manufacturing process in which a powdered material (such as TPU powder) is fused layer by layer using a laser. It can produce complex geometries without support structures, making it suitable for various industrial applications.
