PO hot melt film is often produced by the flow method, can also be produced by the coating method, need to see the characteristics of the specific formula material.
PO hot melt film has good water-washing resistance. According to the different materials, it also has good low-temperature resistance or high-temperature resistance.
The highest temperature resistance is about 100℃. The advantage of PO hot melt film is that it has a very good bonding effect on metal, plastic, wood and other materials, not only strong bonding, but also high temperature boiling resistance, weather resistance.
PO hot melt film has the opportunity to be used in the field of building materials which often have high requirements for weather resistance.
The most mature, and currently the largest amount of PO hot melt film application is the manufacture of aluminum-plastic plate, used for bonding aluminum skin and plastic plate.
In addition, the manufacture of aluminum honeycomb panels also has some demand for this kind of hot melt film.
Plus, it is also can be used for refrigerators, to bond aluminum tube onto the evaporator plate
