To hot melt adhesive film compare the difference between hot melt adhesive and pressure sensitive adhesive, another adhesive needs to be added-hot melt pressure sensitive adhesive. Hot-melt adhesives, hot-melt pressure-sensitive adhesives and pressure-sensitive adhesives should be said to be the more common types of adhesives on the market, and they are also the types of adhesives that are developing relatively quickly. But their names are relatively similar, and it is indeed easier to confuse them. Although the names are similar, they are still quite different in nature. Let's start with hot melt adhesives. Hot melt adhesive is a kind of hot adhesive.

 

 

 

There are many types of its products, such as hot melt glue stick, hot melt adhesive block, hot melt adhesive pellets, hot melt adhesive powder, hot melt adhesive film, hot melt omentum, Hot melt film, etc. At the same time, it can be divided again according to the relevant materials, melting point temperature and other dimensions. In essence, hot melt adhesive refers to an adhesive that changes when the temperature is changed while the chemical properties are unchanged. Because of its fixed form at room temperature, it is very convenient for packaging, transportation and storage, and the application industry span is relatively large, such as.

 

Hot melt adhesives can be used in automobile manufacturing, shoe material processing, clothing production, metal material processing, luggage, home textiles, leather and other fields. Pressure-sensitive adhesives are mainly used in the market for polypropylene sealing, masking paper, pvc electrical tape and other applications. Pressure-sensitive adhesives are actually an independent branch in the field of adhesives. They are dry and sticky. Sometimes pressure-sensitive adhesives are also used.

 

Called non-dry hot-melt pressure-sensitive adhesive, it has the feeling of integrating both hot-melt adhesive and pressure-sensitive adhesive. Of course, this statement is not very accurate. Hot-melt pressure-sensitive adhesives have some of the characteristics of hot-melt adhesives and pressure-sensitive adhesives. The advantages of hot-melt pressure-sensitive adhesives are that their production costs are relatively low, and they can be bonded with a little pressure on use. The disadvantage is that they are sticky. The contact force will change with the temperature.
