In recent years, the influence of the Asian sales market in the world has gradually increased, and under the natural environment of the slowdown of the overall growth trend of the world economic development, hot melt adhesive has become a shining point in the global adhesive sales market. Hot melt adhesive is a kind of moldable adhesive, in the corresponding temperature range its physical situation changes with the change of ambient temperature, and the chemical characteristics will not change, its non-toxic and odorless, is an environmentally friendly chemical product. This is because hot melt adhesives do not include solvents and are non-volatile. Compared with solvent-based, oily, water-based adhesives, etc., hot melt adhesives are very environmentally friendly.
Features of hot melt adhesives:
1. The hot melt adhesive solid content is 100%, convenient storage, energy saving, environmental protection and health, non-toxic and harmless, and will not bring secondary pollution to the natural environment.
2. Fast curing speed, can be used for modern high-speed assembly line production operations.
3. Convenient construction, hot melt adhesive can choose many gluing methods, such as spraying, roller coating, scraping, etc.
4. Can be used for bonding of many materials.
There are more and more varieties of hot melt adhesives, and they are more and more widely used, which can bond leather, glass, metal, wood, luggage plastic, medical, textiles, etc., but are mainly used in labels, express bags, automobiles, packaging (corrugated and thick cartons), wireless binding of books, and woodworking welt.
Hot melt adhesive under different applications is different, we can not treat different glue with the original cognition, that is like people, some people will be afraid of cold, some people will be less afraid of cold, which is related to people's physique. The characteristics of each hot melt adhesive are like human physique, facing the same ambient temperature will have different reactions, which has long been determined in its research and development stage.
