how can the performance of tpu film be improved?

tpu filmit is a polymer material with excellent elasticity and wear resistance, and is often used to make highly durable products such as shoes and hydration bags. however,TPUthe film also has some shortcomings, such as low-temperature embrittlement, aging and other problems. these problems may cause the performance of the tpu film to decrease, thereby reducing the service life and quality of the product. therefore, improving the performance of tpu films is of great significance to increasing its application value. this articletpu film manufacturershow to improve the performance of tpu film will be discussed from the following aspects.

1. improve material formula

during the preparation process of tpu film materials, a variety of additives need to be added, such as plasticizers, stabilizers, light stabilizers, etc. these additives can enhance the heat resistance, weather resistance and other properties of the film material. therefore, by improving the type and ratio of additives, the performance of tpu films can be improved. for example, adding fillers such as alumina can improve the mechanical properties and burst strength of the tpu film; adding additives such as orthosulfonic anhydride can improve the aging resistance of the tpu film.

2. optimize process parameters

during the preparation process of tpu films, the setting of process parameters also has a great impact on the performance of the film material. by optimizing process parameters, the physical and mechanical properties of tpu films can be improved. for example, increasing the tensile deformation speed can improve the tensile strength and elastic modulus of the tpu film; adjusting the oven temperature and time can improve the heat resistance and heat shrinkage of the tpu film.

3. adopt composite technology

tpu filmthe performance can also be improved by using composite processes. composite is a new type of film material made by processing two or more film materials with different properties. through compounding, various physical properties can be combined to form a thin film material with multiple properties. for example, combining tpu film with pet film can improve the tensile strength and wear resistance of the film material.

4. improve subsequent processing technology

tpu films can be made into various products, such as shoes, water bags, etc., after certain processing. improving subsequent processing techniques can also improve the performance of tpu films. for example, in the production process of footwear, the cushioning and comfort of shoes can be improved by adding new materials such as air cushions; in the production process of water bags, the durability of water bags can be improved by optimizing the joint method and strengthening the material thickness. and sealing.

5. strengthen testing and detection

the performance improvement of tpu films requires the support of testing and inspection. only through continuous testing and inspection can problems with the film be discovered. therefore, strengthening testing and inspection is also an important means to improve the performance of tpu films. for example, advanced testing instruments such as thermogravimetric analyzers and infrared spectrometers can be used to comprehensively test and analyze the physical and chemical properties of the tpu film to identify existing problems and provide technical support for further improving the performance of the tpu film.

in summary, the performance of tpu films can be improved by improving material formulas, optimizing process parameters, adopting composite processes, improving subsequent processing techniques, and strengthening testing and testing. of course, the performance improvement of tpu films still needs to be continuously explored and summarized in practice to provide more technical support for its application.
