Car clothingTPU base film processing technology
TPU film is made on the basis of TPU granules through special processes such as calendering, casting, film blowing, and coating. formed film. Because TPU film has the characteristics of high moisture permeability, air permeability, cold resistance, heat resistance, wear resistance, high tension, high pulling force, and high load support, its application is very wide, and TPU film can be found in all aspects of daily life. For example, TPU films are used in packaging materials, plastic tents, water bladders, luggage composite fabrics, etc.
At present, TPU film is used in the automotive field, and the most popular one is TPU invisible car clothing.
Structurally speaking, TPU invisible car clothing is mainly composed of functional coating, TPU base film and adhesive layer. Among them, the TPU base film is the soul of invisible car clothing, and its quality is very important, and its performance requirements are extremely high.

The processing technology of TPU base film for car clothing is analyzed, and the process points such as dehumidification and drying, process temperature, filtration, melt pump, screw, and die are analyzed. Each step is critical to the production of car clothing.
TPU raw materials are currently widely used in the market. Today we will take a look at the uses of various TPU molded products currently on the market:

Various gears; seals (mainly wear-resistant and oil-resistant); anti-vibration parts; mold needles; bushings; bearings
Covers; connectors; rubber screens; printing glue Rollers, etc.
TPU is thermoplastic polyurethane, which is divided into polyester type and polyether type. It has a wide hardness range (60A-85D), is wear-resistant, oil-resistant, transparent, and has good elasticity. It is widely used in daily necessities and sporting goods. , toys, decorative materials and other fields are widely used. Halogen-free flame-retardant TPU can also replace soft PVC to meet the environmental protection requirements of more and more fields. There are many TPU brands and grades, and the quality varies. When choosing TPU, it is best to go through detailed evaluation and demonstration, otherwise you will not get the best cost-effective result.
