EVA hot melt adhesive films are a prominent type within the category of hot melt adhesive films, renowned for their ability to compound a variety of materials. They are particularly crucial for materials that are not heat-resistant, such as EVA foam, PE materials, and seamless wall fabrics.
When working with EVA hot melt adhesive films, it's important to be aware that the melting point and the application temperature environment can differ.
The primary constituent of EVA hot melt adhesive films is ethylene-vinyl acetate (EVA), which has a melting point of around 80 degrees Celsius. This is considered relatively low among hot melt adhesive films, earning it the designation of a low-temperature hot melt adhesive film. The typical melting point range for EVA hot melt adhesive films is generally accepted to be between 70 to 80 degrees Celsius, and the storage requirements for temperature and environment are relatively low.
During application, the temperature usually needs to exceed the melting point by about 20 to 30 degrees to ensure the adhesive film melts sufficiently and exerts its bonding strength. As a result, the common application temperature for EVA hot melt adhesive films is around 90 to 120 degrees Celsius.
In high-temperature applications, EVA hot melt adhesive films exhibit double-sided adhesion properties, making them suitable for compounding with various types of materials. However, at room temperature, the EVA hot melt adhesive film is a stable solid and does not possess adhesive properties.
