introduction and characteristics of tpu hot melt adhesive film ingredients

the main component of tpu hot melt adhesive film is tpu, which is called thermoplastic polyurethane elastomer rubber in china. this material has the characteristic of exhibiting good elasticity with increasing melting point temperature.

low-temperature tpu hot-melt adhesive film has no elasticity, while high-temperature tpu hot-melt adhesive film has good elasticity. tpu hot melt adhesive film has some common characteristics of polyurethane materials, such as soft material, cold resistance, and water resistance. compared with other materials, tpu hot melt adhesive film has a softer feel at the same thickness and is very suitable for composite bonding of textile fabrics in the clothing field.

tpu hot melt adhesive membrane has good tensile properties and resilience properties, and can be used for bonding various types of materials that require elasticity. it has good water-wash resistance and can be washed and machine-washed multiple times without delamination. its water-wash resistance is second only to pes hot-melt adhesive film. the melting point (melting range) of tpu hot-melt adhesive film is around 105-115℃, which is a medium-temperature hot-melt film. the recommended use temperature is around 125℃-150℃.
