Hot melt adhesive (English name: HotGlue) is a plasticity adhesive. Its physical state changes with temperature in a certain temperature range, and its chemical properties remain unchanged. It is non-toxic and tasteless and is an environmentally friendly chemical product. Because the product itself is solid, easy to package, transport, storage, solvent-free, non-polluting, non-toxic type; and the production process is simple, high value-added, high bonding strength, fast speed and other advantages are favored.
How to use hot melt adhesive
First: choose hot melt color
Due to the color of the adherend, the color requirements of the hot melt adhesive should be different. If the adhesive itself does not have special requirements for color, it is recommended to use yellow hot melt adhesive. Generally, yellow hot melt adhesive is better than white.
Second: surface treatment by bonding
The surface treatment of the adherend by the hot melt adhesive is not as strict as other adhesives, but the dust and oil on the surface of the adhesive should be properly treated to make the hot melt adhesive better.
Third: working time
Fast work is a major feature of hot melt adhesives. The working time of hot melt adhesives is generally about 15 seconds. With the wide application of modern production methods - assembly lines, the working time of hot melt adhesives is required to be shorter and shorter.
Fourth: Anti-warming
Hot melt adhesives are sensitive to temperature. When the temperature reaches a certain level, the hot melt adhesive begins to soften; below a certain temperature, the hot melt adhesive will become brittle, so the choice of hot melt adhesive must fully consider the ambient temperature change.
Is hot melt glue toxic?
Non-toxic. Hot melt adhesive is a plastic adhesive. Its physical state changes with temperature in a certain temperature range, and its chemical properties remain unchanged. It is non-toxic and is an environmentally friendly chemical product. It has a mild odor when melted, can be worn with a mask, and can be placed next to a small smoking machine. Although some hot melt adhesives are less toxic, they should be protected during melting to avoid inhaling steam and irritating the respiratory tract.
What can hot melt adhesive stick?
1. Hot melt adhesive for fabric:
Mainly used in the production of shoes, shoes and hats. The garment using the hot melt adhesive not only has a crisp, plump appearance quality, but also has a natural smoothness after washing and can be worn without ironing. The shoes and caps using the glue are light and breathable, and have good shape retention, especially for the shoe industry, and also have the advantages of comfortable wearing and reducing shoe odor.
2, packaging and bookbinding hot melt:
At present, packaging and sealing of food, beverages, instant noodles, cigarettes, beer, medicine, etc., mostly use hot melt through a sealing machine. The bookbinding industry has now abolished the old lines and nails, and switched to the hot melt bonding process, which not only improves the quality of binding, but also greatly speeds up the binding speed.
3, hot melt pressure sensitive adhesive:
Mainly used for women's sanitary napkins, children's diapers, sick mattresses, old age incontinence products. Especially the latter, with the aging of China's population structure. The demand for incontinence products in the future will increase rapidly.
