First of all, everyone needs to be thermo-adhesive film 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 bonding properties. Moreover, the application range of TPU hot melt adhesive film is very wide, which is mainly related to its multi-melting point range. Hot melt adhesive film is divided into TPU hot melt adhesive film, PA hot melt adhesive film, PES hot melt adhesive film, EVA hot melt adhesive film and PO hot melt adhesive film 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.
