TPU film and TPU hot melt adhesive film: performance differences and cross-border application analysis
1. Core definition and material properties
TPU film (thermoplastic polyurethane film) is a polymer elastomer based on polyurethane. It has the dual characteristics of rubber and plastic. It has the advantages of high elasticity, cold resistance (still soft when it remains -30℃ to -40℃), wear resistance, waterproofness and other advantages.
Its hardness range is wide (80A±3A), and it can be flexibly applied to clothing, automotive interiors, medical devices and other fields. The TPU hot melt adhesive film is a adhesive film made of adding adhesive components to the TPU substrate, and seamless bonding between materials is achieved through heating and melting. Its melting point range is usually 55℃ to 125℃, and the processing temperature is recommended to be 110℃-170℃, with high bonding strength and environmentally friendly and solvent-free. Compared with traditional adhesives, TPU hot melt adhesive film does not require curing time and supports high-efficiency processes such as high-frequency welding and hot pressing composite.
2. Performance comparison and differentiation advantages
Physical properties
Elasticity and flexibility: The elongation of the TPU film is as high as 300%, suitable for dynamic stretching scenarios (such as sports uppers); while maintaining elasticity, the TPU hot melt adhesive film focuses more on bonding performance, especially suitable for the composite of heterogeneous materials (such as fabrics and plastics).
Temperature resistance: The TPU film has outstanding low temperature resistance (not brittle if -40℃), while the TPU hot melt adhesive film can achieve high temperature resistance through modification (some models withstand above 110℃), meeting the strict needs of automotive interiors and electronic components.
Environmental protection and safety are both RoHS standards and are non-toxic and odorless, but the TPU hot melt adhesive film does not require solvent coating, and the production process is lower in carbon
In the medical field, TPU hot melt adhesive film can directly contact the skin (such as medical dressings), while TPU membrane is used in structural components such as airbags and catheters.
