TPU extrusion is the process of heating thermoplastic polyurethane material until it softens, then shaping it using an extruder, and finally cooling it to form the desired product.
Extrusion TPU granules are typically supplied in cylindrical or lentil-shaped forms.
Main Feature of TPU Extrusion
TPU has excellent elasticity, wear resistance, tear resistance and compression resistance, can withstand high-intensity mechanical loads, and is suitable for applications that require high durability and high-strength materials.
TPU has excellent tolerance to a variety of chemicals such as oils, greases, solvents, etc., and can maintain its performance in harsh chemical environments.
TPU is a thermoplastic material that softens and is easy to shape when heated, and maintains its shape after cooling. This makes TPU have good processability and can be used to manufacture various products through different molding methods (such as extrusion, injection molding, blow molding, etc.).
TPU can be made into transparent or various colors to meet the appearance requirements of different products. It is widely used in consumer products and industrial fields.
TPU has good high temperature resistance and can maintain its physical properties within a certain temperature range. It is suitable for applications in high temperature environments.
TPU has a certain UV resistance, so it can maintain stability for a long time in the outdoor environment and in the environment exposed to the sun.

-Hose material: Air tube, hose, fire hose, cable & wire.
-Sheet Material: Film, sheet, conveyor belt.
Storage
1.Avoid inhaling thermal processing fumes and vapors
2.Dust can be generated by mechanical handling equipment.
Avoid inhaling dust.
3.Use suitable grounding measures to avoid electrostatic charges when handling.
4.Pellets on the floor may be cause slips and falls.
5.Store in a cool and dry area.
6.Keep in tightly sealed.
7.It is required to totally dry before molding, especially during extrusion molding, blow molding, and film blowing molding.
8.Requirements for moisture content strictly, especially in humid seasons and high humidity places.
