Hot melt adhesive film in TPU material is a hot melt adhesive film product made of thermoplastic polyurethane as the main raw material. Thermoplastic polyurethanes (TPU) is a polymer with many repeating urethane (-OOCNH-) groups on the main chain of the molecule. Polyurethane is a non-toxic polyurethane made by polyisocyanate and polymer polyol. , Odorless, compared with other types of hot melt adhesives, the biggest feature is good elasticity, excellent mechanical properties, very suitable for high-speed bonding automatic production, will not pollute the environment, often used for bonding fabric, leather, plastic, metal, glass and other materials.
