TPU hot melt adhesive films and EVA hot melt adhesive films are two of the most used hot melt adhesive film products in the hot melt adhesive film industry. They are used extensively in textile laminating and many industries for material development applications. So what is the difference between TPU hot melt adhesive film and EVA hot melt adhesive film? Here's a brief explanation.
First of all, the raw materials of TPU and EVA hot melt adhesive films are different. TPU hot melt adhesive films are made of thermoplastic polyurethane, while EVA hot melt adhesive films are made of ethylene-vinyl acetate polymer. These are two completely different chemical materials.
Secondly, TPU hot melt adhesive film and EVA hot melt adhesive film are suitable for bonding materials are different. EVA hot melt adhesive film has a wide range of material adaptability, for most materials can form a certain bonding strength. In contrast, TPU hot melt adhesive film is less adaptable than EVA hot melt adhesive film. But for specific materials, the bonding may be much stronger than EVA hot melt adhesive film.
TPU hot melt adhesive film generally has better elasticity than EVA hot melt adhesive film. Therefore, in some elastic materials bonding, TPU hot melt adhesive film will be more advantageous if applied. In addition, TPU hot melt adhesive film has better waterproof performance than EVA hot melt adhesive film. Therefore, for some products that need to be washed, especially in the garment field, TPU hot melt adhesive film will be used more often.
