TPU hot melt adhesive film, like EVA hot melt adhesive film, is one of the most common types of environmentally friendly hot melt adhesive films. TPU hot melt adhesive film is a hot melt adhesive film product made of TPU as the main raw material. The chemical name of TPU is thermoplastic polyurethane, which belongs to the polyurethane system. TPU hot melt adhesive films are usually colorless, transparent or foggy.
1. Advantages of TPU hot melt adhesive film
TPU hot melt adhesive film has better elasticity than other types of hot melt adhesive film, and can be used where elasticity is required. Furthermore, TPU hot melt adhesive film can maintain its original material characteristics in a lower temperature environment and has good cold resistance. Furthermore, since the material is soft, TPU hot melt adhesive film will have a better feel. Combined with TPU hot melt adhesive film, it has better washing resistance, so it is easy to understand that it is widely used in the field of clothing.
2. Special types of TPU hot melt adhesive film
There are some special types of TPU hot melt adhesive films depending on where they are used. If used in places where elasticity is required, a highly elastic TPU hot melt adhesive film will be used. In applications in the field of clothing, there is also high temperature resistant water-washable TPU hot melt adhesive film. When bonding some transparent materials, TPU hot melt adhesive film is often required to have good aging resistance. At this time, anti-yellowing TPU hot melt adhesive film is needed. TPU hot melt adhesive film usually has two forms with paper and without paper. TPU hot melt adhesive film with paper is produced using a coating method. Substrate-free hot melt adhesive films without paper are produced using the casting method.
III. Application areas of TPU hot melt adhesive film
TPU hot melt adhesive film uses a pressing machine or roller laminating machine to composite materials. Currently, the most commonly used are hot melt adhesive film for TPU clothing and hot melt adhesive film for TPU shoe materials. Of course, in some other fields, TPU hot melt adhesive film is also used. For example, for the bonding of handicrafts and certain plastics, TPU hot melt adhesive film often has good effects.
