TPU hot melt adhesive film advantages: soft material, good cold resistance, washable!
So, what are the specific advantages of TPU hot melt adhesive film, so that it has obtained such a wide range of applications? Let's understand together.
The main component of TPU hot melt adhesive film is thermoplastic polyurethane, so it is also called thermoplastic polyurethane polyurethane hot melt adhesive film. TPU hot melt adhesive film has some common characteristics of polyurethane materials, such as soft material, cold resistance, and water resistance.
Advantage 1: soft material
Compared with other materials, TPU hot melt adhesive film has a softer feel at the same thickness, so it is very suitable for compounding and bonding textile fabrics in the field of clothing. The cloth bonded by TPU hot-melt adhesive film will be very comfortable to wear on the human body, and will not have a plastic or foreign body feeling.
Advantage 2: Good cold resistance
In addition, when hot-melt adhesive film is used in practice, cold resistance is very important. For example, the cold-resistant performance of PA hot-melt adhesive film is lacking. If it is not modified, it will become very hard and brittle in winter, affecting the final bonding effect. The TPU hot melt adhesive film does not have such a problem, and it can maintain good softness even at minus 30-40 ° C.
Advantage 3: Washable
Another advantage of TPU hot melt adhesive film is that it is very resistant to washing. We know that TPU hot melt adhesive film is often used for cloth bonding in the field of clothing. The clothing needs to be cleaned during use. The water-washing resistance of TPU hot melt adhesive film makes our clothing more durable.
Now, do you understand the advantages of TPU hot melt adhesive film? The three advantages of softness, cold resistance, and washing resistance are the core advantages of TPU hot melt adhesive film, which makes it widely used in the textile field.
