Hot melt adhesive study report from a new empolyee

2023-06-07

Today, as a new employee who has just come into contact with the hot melt adhesive industry, I learned the training knowledge related to hot melt adhesive shared by my colleagues and made a learning summary.

After these trainings and thinking, the questions that arise are believed to be the knowledge points that many customers are concerned about.

Hot melt adhesive is a kind of adhesive with many categories, so it is necessary to understand its specific classification. Different sources of information classify it differently, and we need to list products that are parallel to ours.

At present, iSuoChem mainly promotes PA hot melt adhesives (PA is an organic binder), what is the difference compared with other products? Q1


What are the direct-use products that compete with us in these various categories? Q2

What are the advantages and disadvantages of other products? Q3

What are the advantages and disadvantages of our products? Q4

What are the acceptable products on the market for this use? Q5

(We have summarized the specific answers, and you can consult relevant businesses at any time to obtain industry standard answers.)


When I searched on Google, I found that there are many hot-melt adhesive films for different products (adhesive film, adhesive web, and adhesive powder are also the three main application products promoted by iSuoChem). Is this the downstream market of hot-melt adhesives? Q6

There are also some manufacturers who make hot-melt adhesives in square shapes. According to different uses, most sellers can recommend different hot-melt adhesives, but they do not indicate the specific types of hot-melt adhesives. Has iSuoChem marked the specific type of hot melt adhesive? Q7 (The answer is yes.)


For the learning summary of our PA hot melt adhesive, first of all, the raw material we use is cotton hemp catalpa oil. In the manufacturing process, similar to polyamide resin, oleic acid is extracted, catalyst is added, polymerization reaction, acidification reaction, monoacid, dimer acid + ammonia are distilled, polycondensation, and then heat is produced through underwater granulation Melt glue. As a green hands, is this understanding correct? Do you have a different opinion? Q8


The products we currently have can be divided into many grades according to the content on the catalogue. Why use the following grades? Q9
