TPU hot melt adhesive film production process

TPU hot melt adhesive film production process
TPU film is a sustainable modified material that uses TPU to make new hot-melt adhesive products, hot-melt adhesive films,

and has gradually begun to start and develop. Compared with the current main EVA hot melt adhesives and synthetic rubber hot melt adhesives,

TPU hot melt adhesive films can meet customer requirements for high viscosity,

and the physical properties of TPU (such as elasticity, high mechanical strength, etc.) are also very good.

TPU hot melt adhesive film can be applied in many areas where ordinary hot melt adhesive film cannot be used.For example,

the TPU film shoe upper material usually consists of a surface PU layer, which is used to color the shoe surface and print patterns.

The middle layer is a TPU film, and the main part of the fabric determines the main performance characteristics of the shoe; the bottom is a TPU hot melt adhesive film,

which is mainly an adhesive, which plays the role of realizing the adhesion between the TPU upper material and the shoe body.
The TPU film upper material can be directly combined with the shoe body through the excellent adhesion performance of the bottom TPU hot melt adhesive film,

and it does not need the sewing process, so it is also called TPU seamless shoe upper.

The advantages of TPU hot melt adhesive film are washing resistance, bending resistance, cold resistance, good adhesion, hydrolysis resistance, easy processing, and stable quality; it has a wide range of applications.
