How much is the use of hot melt adhesives?
1.1Definition of hot melt adhesive

Hot melt adhesive is an abbreviation of hot melt adhesive. It is an important category of adhesive. It has the characteristics of 100% solid content, no solvent, environmental protection, non-toxic, and fast curing. It usually means that it is solid at room temperature. When heated to a certain temperature It melts into a viscous liquid. After coating and wetting the adherend, it is pressed and cooled to room temperature, and the adhesive is bonded in a few seconds.

It is widely used in industries such as automated packaging, sanitary products, label tape, medical and pharmaceutical, automotive interiors, building waterproofing, furniture furniture, printing and binding, shoemaking, clothing and other industries.

1.2Classification of hot melt adhesive

Divided by the main material: can be divided into polyethylene-vinyl acetate (EVA) hot melt adhesive, polyamide (PA) hot melt adhesive, polyurethane (PU) hot melt adhesive, polyolefin (PO) hot melt adhesive , Block copolymer (SBC) hot melt adhesives, etc .;

Divided by shape: it can be divided into hot melt adhesive particles, hot melt adhesive sticks, hot melt adhesive blocks, hot melt adhesive films, hot melt adhesive powder, etc .;

Divided by application: It can be divided into filter hot-melt adhesive, automatic packaging hot-melt adhesive, automotive interior hot-melt adhesive, label hot-melt adhesive, tape hot-melt adhesive, plaster hot-melt adhesive and so on.

Other classifications: response, color, natural, pressure sensitive, etc.

1.3Application fields of hot melt adhesive

Hot melt adhesive products have been applied to all aspects of people's life, covering all areas of people's eating, wearing, living, using, walking, playing, eating bowls of instant noodles, drinking bottles of water, drinking glasses of wine, wearing clothes, shoes, hats , Halls, houses, cars, trains, airplanes, refrigerators, color TVs, washing machines, toilet paper, toothpaste, soap, handicrafts, decorative paintings, craft flowers, children's toys, gifts, etc. that beautify the living space There are hot melt adhesive applications. It can be said that the application of hot melt adhesives is ubiquitous in modern people's lives.

1.4Characteristics of hot melt adhesive

Technical characteristics:
Fast curing speed, curing in a few seconds, has the characteristics of heating and melting, cooling and sticking, which is convenient for continuous and automated high-speed operation, which improves production efficiency and reduces costs;

100% solid content, no solvent, environmental protection, non-toxic, energy saving, no secondary pollution to the environment;

Non-reactive hot-melt adhesive can be repeatedly melted and bonded, especially suitable for bonding of components required by special processes, such as the repair of some cultural relics;

It can be used for a wide range of objects, both bonded and sealed, and has a wide range of applications. It has good adhesion to paper, plastic, metal, ceramics, etc .;

Convenient construction, small equipment footprint, labor saving, spraying, roller coating, scraping coating, spot coating, line coating, etc.

Market characteristics:

Hot melt adhesive is applied to customer's products. Relative to the total value of the product, its own value is very small, but the impact on the customer's product is very large, often because of the poor adhesion of the hot melt adhesive, the overall value of the customer's product is lost.
