What industries are hot melt adhesives commonly used in? How to choose suitable hot melt adhesive pr

When it comes to hot melt adhesive, many netizens may not be very clear because it is not easy for us to come into contact with it in production, but it can be used in many fields of life. Hot melt adhesive is a type of adhesive with strong plasticity. And it will change its physical condition within a certain temperature range, but its chemical properties remain unchanged, and it is non-toxic and odorless, making it a relatively environmentally friendly chemical bonding material. Due to its convenient packaging and transportation, as well as low cost, it has been widely favored.

The cost of hot melt adhesive is relatively low and suitable for large-scale use in production. Its characteristics determine that it is a non-toxic and harmless environmentally friendly material. Therefore, when using hot melt adhesive, apart from a slight pungent smell that may occur during melting, the adhesive itself is completely harmless to the body.

Hot melt adhesive products have been applied to various aspects of people's lives, covering various fields such as eating, wearing, living, using, traveling, and playing. Hot melt adhesive is used in eating bowls and making instant noodles, drinking bottles of water, drinking glasses of wine, wearing clothes, shoes, hats, buildings, houses, cars, trains, airplanes, refrigerators, televisions, washing machines, toilet paper, toothpaste, soap, handicrafts, decorative paintings, craft flowers, children's toys, gifts, etc. that beautify living spaces. It can be said that the application of hot melt adhesive is ubiquitous in modern people's lives.

1、 Label industry: Hot melt adhesive is an important type of label adhesive. Within a certain temperature range, the physical state of hot melt adhesive changes with temperature, while its chemical properties remain unchanged. It has good initial adhesion and stable holding force. Due to its solid nature, it is easy to package, transport, store, and has a simple production process, high added value, high adhesive strength, fast speed, solvent-free, pollution-free, non-toxic, odorless, and environmentally friendly advantages, and is highly favored. Nowadays, hot melt adhesive has been widely used in the label industry, and conversely, it has also promoted the development of the label adhesive industry.

2、 Velcro: In recent years, Velcro has widely penetrated into human daily life, and its use in the market can be said to have blossomed in recent years. The most common application markets include packaging, such as the automotive industry, doors and windows (screens), clothing, shoes, luggage, household items, furniture, stationery, transportation vehicles, medical equipment, sports equipment, construction, etc. Adhesive tape can be easily sewn onto most fabrics by car. However, for materials such as metal, glass, concrete, wood, ceramics, and hard plastics that cannot be sewn together, an additional layer of pressure-sensitive adhesive needs to be applied for bonding. You can use Velcro hot melt adhesive to bond here.

3、 Express bag industry: Due to the rapid growth of logistics and express delivery volume, express bags are widely used as packaging consumables. To use express bags, they need to be sealed, and the best way to seal express bags is to apply quick sealing bag adhesive to make the bag seal less likely to pop open and achieve the best bonding effect. Express bag hot melt adhesive is a type of adhesive specifically designed for the express bag production industry. It has strong initial adhesion, good temperature resistance, and strong antioxidant capacity. Many packaging products used in the express industry today use this type of adhesive.

4、 The packaging industry has been developing rapidly, and at the same time, it is increasingly inseparable from hot melt adhesive. It is not just for some ordinary paper box sealing, but even for paper packaging industry specific hot melt adhesive, which is becoming more and more popular. Excellent heat resistance, excellent adhesion performance, and light odor. Hot melt adhesive is very suitable for the packaging industry, and it also meets the requirements of harmless and non-toxic development, such as energy utilization and environmental pollution. Hot melt adhesive is a completely solid shape that does not contain water or other solvents, and has no pollution to the environment or solvent toxicity issues. It is suitable for packaging applications such as carton sealing, gift box bonding, handbag bonding, and food and drug packaging.

5、 Automotive industry: Hot melt adhesive is a type of adhesive that is highly environmentally friendly and suitable for high-speed automatic assembly line operations today. The automotive industry is developing rapidly today, especially in China, which has become the world's largest producer and seller of automobiles. With the improvement of automation level in automobile production, the automobile industry requires a large amount of adhesive that can quickly bond and adapt to high-speed automation production while being environmentally friendly. Hot melt adhesive can just meet all the above requirements, so hot melt adhesive is increasingly widely used in the automobile industry, and its usage is also increasing year by year. It has become an irreplaceable adhesive in the automobile industry.

Hot melt adhesive is a solid form at room temperature and can turn into a liquid when heated to a certain temperature. The bonding of hot melt adhesive is to melt the hot melt adhesive through a hot melt adhesive machine. The melted glue turns into a liquid and is then sent to the surface of the object to be glued through the hot melt glue gun and the hot melt glue hose of the hot melt glue machine. After the hot melt adhesive cools down, the bonding is completed. In order to fully utilize the advantages of hot melt adhesive in bonding, it is necessary to match high-quality hot melt adhesive with corresponding quality and reliable performance hot melt adhesive machines.

3、 The tips for selecting hot melt adhesive are as follows:

1. Choose a color. Generally, hot melt adhesive comes in two colors: yellow and white. Generally speaking, yellow hot melt adhesive has better adhesion than white adhesive.

2. Temperature resistance: Generally speaking, the temperature resistance of hot melt adhesive is not very good. If the temperature is too high, softening may occur; If the temperature is too low, the hot melt adhesive will become brittle. So when choosing a hot melt solution, one should consider the temperature changes in the environment.

3. Viscosity, hot melt adhesive has two types of viscosity, namely early viscosity and late viscosity. Only when the early and later adhesiveness are consistent, is it a good hot melt adhesive that keeps the object being bonded stable.
