How to classify TPU hot melt adhesive film

    TPU hot melt adhesive film is an environmentally friendly hot melt adhesive film with excellent performance and is widely used in packaging, shoemaking, textiles, electronics, automobiles and other fields. Due to its unique properties and wide range of applications, the classification methods of TPU hot melt adhesive films are also relatively diverse. This article will classify TPU hot melt adhesive films from different perspectives to better understand their characteristics and uses.

    1. Classification by ingredients

    1. Polyester TPU hot melt adhesive film

    Polyester TPU hot melt adhesive film is a hot melt adhesive film based on polyester. It has high heat resistance and water resistance and is mainly used in shoemaking, textiles, automobiles and other fields.

    2. Polyether TPU hot melt adhesive film

    Polyether TPU hot melt adhesive film is a hot melt adhesive film based on polyether. It has good flexibility and low temperature resistance and is mainly used in packaging, electronics and other fields.

    3. Classification by processing technology

    1. Extruded TPU hot melt adhesive film

    Extruded TPU hot melt adhesive film is produced through an extruder and has good production efficiency and product quality. Its characteristics are diverse shapes, high production efficiency, and stable product quality.

    2. Calendered TPU hot melt adhesive film

    Calendered TPU hot melt adhesive film is produced through a calendering machine and has good thickness control and surface smoothness. Its characteristics are uniform thickness, smooth surface, and good bonding effect.

    3. Coated TPU hot melt adhesive film

    Coated TPU hot melt adhesive film is produced through a coating machine and has good coating quality and bonding effect. Its characteristics are uniform coating, good bonding effect, and high production efficiency.

    4. Classification according to performance characteristics

    1. High temperature resistant TPU hot melt adhesive film

    High temperature resistant TPU hot melt adhesive film can maintain good performance at high temperatures and is suitable for bonding and fixing in high temperature environments. Its characteristics are high temperature resistance, aging resistance and good stability.

    2. Flexible TPU hot melt adhesive film

    Flexible TPU hot melt adhesive film has good flexibility and is suitable for bonding situations that require bending and deformation. Its characteristics are good flexibility, not easy to crack, and wide application range.
