Like EVA hot melt adhesive film, TPU hot melt adhesive film is one of the most common types of environmentally friendly hot melt adhesive film. TPU hot melt adhesive film is a hot melt adhesive film product made of TPU as the main raw material. TPU (Thermoplastic polyurethanes ) The chemical name is thermoplastic polyurethane, which belongs to the polyurethane system. TPU hot melt adhesive film is usually colorless, transparent or foggy.

1. Advantages of TPU hot melt adhesive film‍‍‍‍

Compared with other types of hot melt adhesive films, TPU hot melt adhesive films have better elasticity and can be used in occasions that have certain requirements for elasticity. Moreover, the TPU hot melt adhesive film can maintain its original material properties in a lower temperature environment, and has better cold resistance. In addition, TPU hot-melt adhesive film has a better hand feeling because of its soft material, and it has better washing resistance with TPU hot-melt adhesive film. It is better understood that it has been widely used in the field of clothing.

2. Special types of TPU hot melt adhesive film

TPU hot melt adhesive film has some special types due to different occasions of use. If it is used in occasions that require higher elasticity, a high-elastic TPU hot-melt adhesive film will be used. In the application of clothing field, there is also high temperature washable TPU hot melt adhesive film. When bonding some transparent materials, it is often required that the TPU hot melt adhesive film has good aging resistance. At this time, the anti-yellowing TPU hot melt adhesive film is required. TPU hot melt adhesive film usually has two forms with paper and without paper, and TPU hot melt adhesive film with paper is produced by coating method. Substrate-free hot-melt adhesive films without paper are produced using casting methods.

3. Application fields of TPU hot melt adhesive film

TPU hot-melt adhesive film uses a pressing machine or a roller laminating machine to compound materials. Currently, the most used TPU hot-melt adhesive film for clothing and TPU hot-melt adhesive film for shoe materials. Of course, in some other fields, there are also applications of TPU hot-melt adhesive films. For example, for the bonding of handicrafts and certain plastics, TPU hot-melt adhesive films often have very good results.

4. In-depth inventory of the advantages and disadvantages of tpu hot melt adhesive film

TPU hot melt adhesive film is one of the main types of hot melt adhesive film, and the attention of many hot melt adhesive films TPU hot melt adhesive film has always been very high. It has excellent bonding properties, and it can be used in a wide range of industry types and material types. Many people wonder why tpu hot melt adhesive film is so popular? In this article, let's briefly discuss the advantages and disadvantages of tpu hot melt adhesive film.

Advantages of tpu hot melt adhesive film:

The conventional expression about the characteristics of TPU hot melt adhesive film: it has good high temperature resistance, low temperature resistance, high bonding strength, water resistance, environmental protection, good tensile properties, etc. The above descriptions of the advantages of the tpu hot melt adhesive film are all correct. High temperature tpu hot melt adhesive film has good elasticity and ductility, and high transparency. However, the elasticity of the low-temperature TPU hot melt adhesive film is relatively poor.

The softness of Tpu hot melt adhesive film is also very good, which is very suitable for the use of clothing materials. In addition to softness, its washability is also very good. After lamination, the product can be washed repeatedly without glue opening.

Disadvantages of tpu hot melt adhesive film:

The bonding performance of Tpu hot melt wear is good, but it also has many shortcomings. There are some materials that are not suitable for bonding with tpu hot melt adhesive film. This is mainly related to the compatibility of the material with the hot melt adhesive film.
