Hot melt adhesive films are divided into different materials, such as TPU, TPE, PA, PO hot melt adhesive films, etc., and also have medium, high and low temperatures. The difference between medium, high and low temperature hot melt adhesive films is mainly based on the melting point of the hot melt adhesive film. Different materials have different melting points. Next, Alster will explain the uses and types of low-temperature hot melt adhesive films. Let’s take a look together:
Types of low-temperature hot melt adhesive films
The types of low-temperature hot melt adhesive films mainly include low-temperature TPU hot melt adhesive films and EVA hot melt adhesive films. The melting point of low-temperature TPU hot melt adhesive films is mainly around 70 degrees Celsius. There will be certain differences between different models. The lowest is the PE-DJU90 model, and the melting point can be as low as 40 to 50 degrees. The melting point of EVA hot melt adhesive film is 70 degrees Celsius, which is also a relatively low temperature.
Characteristics of low-temperature hot melt adhesive film
Whether it is low-temperature hot melt adhesive film or medium-high temperature hot melt adhesive film, they all have the basic characteristics of hot melt adhesive film, including good bonding performance, non-toxic, formaldehyde-free and harmless environmental protection and safety performance. Low-temperature TPU hot melt adhesive film is not elastic.
TPU material is a relatively special material. The elasticity will increase with the increase of melting point, and low-temperature TPU has the worst elasticity. Low-temperature TPU hot melt adhesive film has good water washing resistance. In contrast to low-temperature TPU hot melt adhesive film, EVA hot melt adhesive film has elasticity, but poor water washing resistance. Because of the different characteristics of the two, their applications are also different.
Uses of low-temperature hot melt adhesive film
Low-temperature hot melt adhesive film has a wide range of applications, and its flexibility and characteristics make it popular in many industries.
- First of all, low-temperature TPU hot melt adhesive film is often used in the clothing industry, especially in the bonding of sportswear and casual wear, because of its good water washing resistance. The low melting point of this material makes it difficult to damage the material structure when processing ordinary fabrics and leathers, ensuring the durability and comfort of the finished product.
- On the other hand, EVA hot melt adhesive film is widely used in footwear manufacturing due to its excellent elasticity. It can effectively bond the materials of the sole and the upper, providing long-lasting adhesion while maintaining the comfort of the shoes. In addition, EVA is also used in the processing of sponge and foam products, such as mattresses, cushions and toys, because of its good flexibility, it can meet consumers’ needs for product comfort and support.
- In the packaging industry, low-temperature hot melt adhesive film has also found its unique position. Since many packaging materials need to be processed in a low-temperature environment, the use of low-temperature hot melt adhesive film can ensure fast and effective bonding without damaging the product.
The above is a brief introduction to the uses and types of low-temperature hot melt adhesive films. I hope it will be helpful for you to understand hot melt adhesive films.
