What is the difference between TPU hot melt adhesive film and traditional adhesive materials?
There are significant differences between TPU hot melt adhesive film and traditional adhesive materials in many aspects. The following is a detailed analysis of these differences:
1. Form and processing methods
TPU hot melt adhesive film:
Form: usually transparent film.
Processing method: The melting point is low, it is easy to bond after softening by heating, the processing temperature is relatively low, and the pressure requirements are also low.
Traditional bonding materials:
Form: Various, such as granules, liquid, paste, etc.
Processing method: Usually high temperature, high pressure or specific solvents are required for bonding, and the processing process is relatively complex.
2. Adhesion performance
TPU hot melt adhesive film:
It has high adhesion and can form intermolecular bonds with other materials, and the adhesion effect is strong.
Suitable for bonding a variety of materials, such as metal, plastic, textiles, etc.
Traditional bonding materials:
Adhesion varies by material, and some materials may require additional processing to achieve the desired bond.
The scope of application is relatively limited and may not be suitable for all types of materials.
3. Weather resistance and durability
TPU hot melt adhesive film:
It has good weather resistance, can withstand the erosion of ultraviolet rays and ozone, and is not easy to age.
It has excellent wear resistance and can withstand long-term use and friction without being easily worn.
Traditional bonding materials:
Weather resistance varies by material, and some materials may be susceptible to aging due to environmental factors.
The wear resistance may not be as good as TPU hot melt adhesive film and requires regular replacement or maintenance.
4. Environmental protection
TPU hot melt adhesive film:
Usually it has high environmental protection, does not contain harmful substances, and meets environmental protection standards.
There is no need to add solvents during use, which avoids the emission of harmful substances and reduces environmental pollution.
Traditional bonding materials:
Some traditional adhesive materials may contain harmful substances, such as formaldehyde, benzene, etc.
Solvents may be required during use, which may easily produce volatile organic contamination.
5. Application scenarios and flexibility
TPU hot melt adhesive film:
It has a wide range of application scenarios, such as electronics, automobiles, clothing, construction and other fields.
It has high flexibility and can be customized according to specific needs, such as adjusting thickness, color, adhesion, etc.
