1. Introduction to TPU hot melt adhesive film.
TPU hot melt adhesive film is a kind of hot melt adhesive film made of polyurethane (TPU) material, which has excellent weather resistance, abrasion resistance, water resistance, oil resistance and chemical corrosion resistance. It is widely used in the bonding and lamination of various materials, such as plastic, metal, glass, paper, fabric, etc.
2. The recommended thickness of TPU hot melt adhesive film.
The thickness of the TPU hot melt adhesive film can be determined according to the specific application needs. In general, thinner TPU hot melt adhesive films can provide better flexibility and abrasion resistance, while thicker TPU hot melt adhesive films can provide stronger adhesion and weather resistance.
When choosing the thickness of TPU hot melt adhesive film, the following factors need to be considered:
1.Application scenarios: Different application scenarios have different requirements for the thickness of TPU hot melt adhesive film. For example, for the bonding of automotive interior materials, it is necessary to choose a thicker TPU hot melt adhesive film to ensure good weather resistance and abrasion resistance.
2.Material properties: The properties of the materials to be bonded will also affect the thickness selection of TPU hot melt adhesive films. For example, for harder materials, a thicker TPU hot melt film needs to be chosen to ensure a good bonding effect.
3.Process requirements: Different production processes also have different requirements for the thickness of TPU hot melt adhesive film. For example, in the thermoforming process, a thicker TPU hot-melt adhesive film needs to be selected to ensure good molding results.
In summary, the recommended thickness of TPU hot melt adhesive film needs to be determined according to the specific application scenario, material properties and process requirements. Generally speaking, thinner TPU hot melt adhesive films are suitable for applications with high requirements for flexibility and abrasion resistance, while thicker TPU hot melt adhesive films are suitable for applications with high requirements for adhesion and weather resistance.
3. Precautions for use.
When using TPU hot melt adhesive film, you need to pay attention to the following points:
1.Keep it clean: Before use, the dust and dirt on the surface of the TPU hot melt adhesive film should be removed to ensure a good adhesive effect.
2.Control the temperature: The temperature should be controlled during use to avoid damage to the TPU hot melt adhesive film caused by too high or too low temperature.
3.Pay attention to safety: Pay attention to safety during use and avoid contact with ** or inhalation of harmful substances such as steam.
Fourth, summary. In conclusion, choosing the right TPU hot melt film thickness is essential to ensure good bonding and service life. Attention should be paid to keeping clean, controlling temperature and paying attention to safety during use.
