Everyone who has a certain understanding of casting hot fusible film will have a certain interest in TPU hot melt adhesive film. TPU hot melt adhesive film is a special kind of hot melt adhesive film of all materials. It is easy to attract everyone’s attention. First of all, everyone needs to be clear that TPU hot melt adhesive film is a kind of glue. It is an environmentally friendly adhesive. Like all hot melt adhesive films, it has good adhesion.接 performance. Moreover, the application range of TPU hot melt adhesive film is very wide, which is mainly related to its multi-melting point range.

 

As we all know, hot melt adhesive films are divided into TPU hot melt adhesive films, PA hot melt adhesive films, PES hot melt adhesive films, EVA hot melt adhesive films and PO hot melt adhesive films according to different raw materials. The main component of the raw material of TPU hot melt adhesive film is TPU, which is called thermoplastic polyurethane elastomer rubber in Chinese. This material has the property of showing good elasticity as the melting point temperature rises. Therefore, the TPU hot melt adhesive film also has this performance.

 

The low temperature TPU hot melt adhesive film has no elasticity, and the high temperature TPU hot melt adhesive film has good elasticity. TPU hot melt adhesive film has some common characteristics of polyurethane materials, such as soft material, cold resistance and water resistance. Compared with other materials, TPU hot melt adhesive film feels softer under the same thickness, so it is very suitable for the composite and bonding of textile fabrics in the clothing field.

 

The fabric bonded by TPU hot melt adhesive film will be very comfortable to wear on the human body, without plastic or foreign body sensation. These are all thanks to its main ingredient, the characteristics of polyurethane. The above is the introduction of the main components of the raw materials of TPU hot melt adhesive film. Because of the characteristics of the material, TPU hot melt adhesive film exhibits good washing resistance, softness and good elasticity. It is good for textiles, leather, TPU films and sponges. Such materials have good adhesion and are widely used in many fields such as clothing, home building materials, and shoe materials.
