The editor of underwear dispenser manufacturers tells you the difference between underwear hot melt adhesive and pur hot melt adhesive:
Hot-melt adhesive film is what we often say hot-melt adhesive film, and hot-melt adhesive omentum is the new darling of the composite industry in recent years, but also a new member of the hot-melt adhesive family. Both the hot-melt adhesive film and the hot-melt adhesive omentum are functionally used to solve the compound bonding problem of products, and can be regarded as a substitute for each other to a large extent. Since it is possible to replace each other, is it still necessary to develop new products such as hot melt adhesive omentum?
If you only look at the functions of hot-melt adhesive film and hot-melt adhesive omentum, it seems that there is really no need to develop new products. Let us take a look at the difference between the two:
1. Technological difficulty:
The production process of hot-melt adhesive film and hot-melt adhesive omentum is completely different. A friend who has been to the hot-melt adhesive film and hot-melt adhesive omentum production workshop will understand at a glance that the processing of hot-melt adhesive omentum is a workshop The requirements of the production environment are higher, more complex, and the process is more exquisite. The requirements for hot melt adhesive film on the production environment are relatively low. To give a simple example: the production workshop of hot melt adhesive omentum needs to be "sealed". The production workshop of hot melt adhesive film can be said to be an "open" workshop .
2. Differences in physical form:
The physical form of hot-melt adhesive film and hot-melt adhesive omentum have been introduced in detail. Both are stable and solid at room temperature. The difference between them is that the former is like a layer of plastic film and the latter is more like A thin layer of silk fabric.
