The classification of hot melt adhesive film products includes a significant section dedicated to PO hot melt adhesive film as one of the major categories. The term polyolefins can also be abbreviated as PO, which is an abbreviation for the longer term polyolefins. The film that is made of PO hot melt adhesive can also be referred to as polyolefin hot melt adhesive film. Then, what exactly is a polyolefin? Polyolefin is an umbrella term for a group of high-molecular-weight polymers. It most commonly refers to ethylene, propylene, 1-butene, 1-pentene, 1-hexene, 1-octene, and 4-methyl-1-pentene. Polyolefins are a type of thermoplastic resin that are produced by polymerizing or copolymerizing olefins and certain cyclic olefins. Polyethylene (abbreviated as PE) and polypropylene (abbreviated as PP) are the two types of polyolefins that are utilized the most frequently in the production of hot melt adhesive films. These two types of hot melt adhesive films are referred to as PE hot melt adhesive films and PP hot melt adhesive films, respectively. Melt film.

The production of PO hot melt adhesive film typically involves either the casting method or the coating method, depending on the properties of the particular formula material that is being used. The PO hot-melt adhesive film has a high resistance to washing, and depending on the material, it either has a high resistance to low temperatures or a high resistance to high temperatures, and it can withstand temperatures up to about 100 degrees Celsius.

In traditional applications of hot-melt adhesive film, the use of polyurethane adhesive film is not nearly as common as it is in other types of applications. For instance, the garment manufacturing and shoemaking industries do not use PO hot-melt tpu hot melt adhesive film in significant quantities in their production processes. This is not because the bond strength of these materials is an issue for PO hot melt adhesive film, and even PO hot melt adhesive film has better bond strength. PO hot melt adhesive film has a poor feel and typically requires a relatively high temperature to use, which raises the enterprise's overall energy cost. Due to these factors, it is not used in these fields, and the reason for this is that these fields already have high energy costs.

The ability of PO hot melt adhesive film to create a strong bond with a variety of substrates, including metal, plastic, and wood, is one of the film's primary benefits

- In addition to having a powerful adhesive force, it also possesses strong resistance to boiling at high temperatures and resistance to the elements

- Because of this, PO hot melt adhesive films have the potential to be utilized in the realm of building materials, which frequently must fulfill stringent requirements regarding their resistance to the elements

- The production of aluminum-plastic panels, which are used to bond aluminum skins and plastic panels, is the relatively mature application of PO hot melt adhesive film, and it is currently the largest application of this type of adhesive film

- In addition to that, the production of aluminum honeycomb panels generates a certain amount of demand for these types of hot-melt adhesive films

In a nutshell, the PO hot melt adhesive film is a type of hot melt tpu hot melt adhesive film product that possesses excellent performance and possesses good application effect for certain specific materials and specific fields. I have faith that in the not-too-distant future, an increasing number of people who create new materials will comprehend and utilize it.

Why PO and EVA hot melt adhesive films are appropriate for use with PP honeycomb panelsIn accordance with the similarity and compatibility principle, PO hot melt  and PP are both composed of polyolefin materials; consequently, they are more compatible with one another and are able to generate stronger adhesions. However, it is important to note that not all PO hot-melt adhesive films have a good bonding effect on PP plastics. This is something that should be kept in mind. When the bonding strength reaches a certain index, it is necessary to modify the hot-melt  itself in order to maintain the bonding strength. take care of. The composition of tpu hot melt adhesive film is vinyl acetate copolymer, which has a good viscosity to polypropylene. On the other hand, the composition of PP material is polypropylene, and its main composition is similar to polypropylene, so it will have better compatibility. Both of these materials are thermoplastics.

PP honeycomb panel equipped with hot melt adhesive film's desirable characteristicsThe PO hot-melt adhesive film for PP honeycomb panels that can be purchased from cn-hma. com has a melting point of 110 degrees Celsius, is non-elastic, and has a high resistance to washing. Elasticity and poor resistance to washing are characteristics of the EVA hot-melt adhesive film used for PP honeycomb panels. It is utilized in the production of PP honeycomb panels. The low melting point, combined with an operating temperature of 110 degrees Celsius, is one of the reasons for this. Both of these adhesives are kind to the environment, and they are also capable of satisfying the environmental performance requirements of PP honeycomb panels. In general, PP honeycomb panels can fulfill all requirements if they are bonded with PO and EVA hot-melt adhesive films. This is the recommended method., which not only has good bonding performance but also has a bonding effect that lasts for a long time, thereby increasing the service life of PP honeycomb panels and meeting the requirements of environmental protection, can be considered to be an effective solution to the problem of bonding PP honeycomb panels.
