The ingredients that go into making hot melt adhesive that is used at high temperaturesDue to the fact that polyamide resin is used as the primary matrix in the production of high temperature resistant hot melt adhesive, this type of adhesive is also known as polyamide hot melt adhesive. Polyamide resin is a linear thermoplastic resin that possesses a large number of amide groups that are repeated along the main chain of the molecule. When compared to other thermoplastic resins, this one is distinguished by the fact that, regardless of whether it is heated or cooled, the melting and curing processes of the resin both take place within the same limited temperature range. Because of this property, the polyamide hot-melt adhesive is able to rapidly solidify hot melt adhesive film after being heated, melted, and coated following its application during the construction process. Additionally, it is able to have good bonding properties at temperatures that are close to the point at which it begins to soften.

It is possible for the hydrogen on the amide group of the polyamide resin to combine with the electron-donating carbonyl group on another amide group segment to form a strong hydrogen bond. Because this raises the melting point of the resin, the polyamide has excellent flexibility, oil resistance, and bonding properties. These characteristics improve as the molecular weight of the resin moves in the opposite direction. Polyamide hot melt adhesives have a higher softening point and consequently better heat resistance than ethylene-vinyl acetate copolymer hot melt adhesives. This is because polyamide has a higher molecular weight.

In order to make high-temperature hot-melt adhesive, polyamide resin must first be directly copolymerized by dibasic acid and diamine, after which it must be modified and pulverized. And other processes, therefore simplifying the production process and equipment requirements of high-temperature hot-melt adhesive, the production of high-temperature hot-melt adhesive sticks has the advantages of easy control of raw material cost, production process, convenient and accurate control, thus ensuring the stability of product quality. ,,,,,,,,,,,,,,,,,,,,,,,,This hot melt adhesive can withstand high temperatures without losing its excellent bonding performance, and it also has a high softening point, is easy to store, can be promoted and applied quickly, and has a convenient storage option.

Which types of businesses can benefit from using hot melt adhesives?

Which types of businesses can benefit from using hot melt adhesives?.

1. Thermosol for fabrics, which is primarily utilized in the manufacturing of forms, footwear, and headwear. Not only does clothing made with the glue have the appearance of being crisp and full, but it also retains its natural flatness even after being washed and doesn't require any ironing before it can be worn. Shoes and caps that make use of the glue are lightweight and breathable, they have good shape retention, they are especially used in the shoemaking industry, and they have the advantages of comfortable wearing and reduced shoe odor.

2. The use of hot sol for bookbinding and the packaging of goods At the present time, the majority of the packaging and sealing of goods such as food, beverages, instant noodles, cigarettes, beer, and medicine are completed by using hot sol in conjunction with a sealing machine. The bookbinding industry has recently moved away from the traditional thread and staple binding method and adopted the hot-melt bonding process, which not only improves the overall quality of the binding but also significantly increases the rate at which books can be bound.

3. Heat-soluble pressure-sensitive adhesive: This type of adhesive is most commonly used for sanitary napkins for women, diapers for children, hospital mattresses, incontinence products for the elderly, etc. Particularly the latter, as the average age of people living in my country is steadily increasing over time. In the not too distant future, there will be a significant uptick in the demand for elderly incontinence products.

4. Multi-purpose solvent-based hot sol: used in the manufacturing of a wide variety of products, including but not limited to: hot melt transfer printing; sealing liquid crystal material; anti-counterfeiting wallpaper; calligraphy and painting pasting; computer printing; food production date typing; wire and cable agent coding; and so on. The performance of hot sol, but the use of the granular or powder formulations that are already available is not possible. Before it can be utilized in the production of the subsequent process, it is not necessary to first transform it into a liquid in the presence of an appropriate solvent and then coat it on a specific substrate in order to obtain a film that is thin and uniform. Because there are many distinct kinds of solutes, it is possible to prepare a wide variety of solvent-based thermal sols.

5. The use of hot sol for the edge sealing of furniture in my country, which is otherwise devoid of wood. The majority of furniture, with the exception of some high-end pieces that are crafted from solid wood, is typically constructed out of fiberboard, shavings, or sawdust board. Additionally, the edge of the furniture board must be sealed with hot sol in order to protect the edge material. Combined in such a way as to enhance their beauty, just like solid wood furniture would be.

6. Thermoplastic powder coatings Polyethylene (CDPE) and polyvinyl chloride (PVC) powder coatings are the two most common types of powder coatings. Utilized for a variety of things including fish pens, road guardrails, bicycle baskets, racks, refrigerator shelves, and fan covers, among other things. It is possible to make it in a variety of colors depending on the requirements, and it is possible to paint it on the surface of metal products in order to protect and decorate them.

7. Hot melt adhesive film Hot melt adhesive film can www.cn-hma.com be broadly classified into two categories: thermoplastic and thermosetting. It is typically utilized for the bonding of electronic product nameplates, plastics, hardware, mobile phone window frames, and front covers; it can even be used on uneven surfaces.
