what are the main components of tpu hot melt adhesive film?

anyone who has a certain understanding of cast hot melt adhesive film will have a certain interest in tpu hot melt adhesive film. tpu hot melt adhesive film is a special hot melt adhesive film made of a variety of materials. it's easy to get people's attention. first of all, we should know that tpu hot melt adhesive film is a kind of glue. this is an environmentally friendly adhesive. like all hot melt adhesive films, it has good adhesive and connection properties. moreover, tpu hot melt adhesive film has a wide range of applications, which is mainly related to its multiple 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 tpu hot melt adhesive film is tpu, which is called thermoplastic polyurethane elastomer rubber in china. this material has the characteristic of exhibiting good elasticity with increasing melting point temperature. therefore, tpu hot melt adhesive film also has this characteristic.

low-temperature tpu hot-melt adhesive film has no elasticity, while 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 has a softer feel at the same thickness and is very suitable for composite bonding of textile fabrics in the clothing field.

the fabric bonded with tpu hot melt adhesive film is very comfortable to wear on the human body and has no plastic or foreign body feel. all this is due to the properties of its main component, polyurethane. the above is an introduction to the main ingredients and raw materials of tpu hot melt adhesive film. due to the characteristics of the material, tpu hot melt adhesive film shows good washing resistance, flexibility and good elasticity. suitable for textiles, leather, tpu films and sponges. this material has good adhesion and is widely used in many fields such as clothing, home building materials, and shoe materials.
