Aluminum bonding applications : Hot melt adhesive film

Aluminum as a metal material, its light weight and high strength characteristics, so that it is used in many industries, especially the building materials industry. Such as aluminum composite panels, aluminum doors and windows, etc. 

Hot melt adhesive film has been used in many fields besides textile. Aluminum is a more application of hot melt adhesive film bonding material, and hot melt adhesive film is especially unique in dealing with aluminum bonding.

1.Aluminum foil

Aluminum foil is also a kind of material that is pressed into a thin film suit of metallic aluminum, which is widely used. When aluminum foil is used as a finishing material, hot melt adhesive film is often considered for bonding. However, hot melt adhesive film requires special machine and process considerations when bonding aluminum foil, otherwise, when bonding thinner aluminum foil, wrinkling will occur, resulting in defective products.

It is worth mentioning that a lot of aluminum foil is laminated with PET film, and sometimes it is bonded with PET and not with aluminum foil surface when bonding, which requires a lot of material users to pay attention to.

2. Aluminum honeycomb panel

The traditional method of bonding aluminum honeycomb panels is to use the polyurethane system adhesive, which has low efficiency of bonding. The use of hot melt adhesive film instead of traditional polyurethane adhesive bonding can increase the efficiency of bonding and increase the cost of environmental specifications.

3. Aluminum plastic plate

Aluminum plastic plate bonding is the use of hot melt adhesive film more mature industry, aluminum plastic plate production is the use of PET composite aluminum film and PE plastic between the composite together, the middle of the use of hot melt adhesive film to composite. This kind of hot melt adhesive film lamination often uses continuous lamination production method, the production efficiency is very high, the amount of adhesive film demand is also quite high.

4. condensing evaporator

Condensation evaporator is a small part of the refrigerator, often involving aluminum tube and aluminum plate bonding between, this part of the bonding is also widely used hot melt adhesive film bonding this solution. As it is the aluminum tube is a circular cross-section, the actual bonding surface is also a line, the bonding surface is small, so the adhesion force of the hot melt adhesive film is still relatively high.

The main applications of hot melt adhesive film involving aluminum bonding are about the above, of course, there must be many kinds of aluminum bonding applications that we have not yet covered, if you have the needs of this area, you can always contact us.
