Hot melt adhesive classification Daquan


1. according to the chemical composition of classification:
1. Polyolefin Hot Melt Adhesive
Polyolefin hot melt adhesives include polyethylene hot melt adhesives and polypropylene hot melt adhesives. Polyethylene hot melt adhesive is mainly used in cartons, carton packaging, food packaging container sealing, non-woven production, carpets, automotive carpet backing, clothing lining bonding.
 
2. Ethylene and its Copolymer Hot Melt Adhesive
In the ethylene copolymer hot melt adhesive, ethylene-vinyl acetate copolymer hot melt adhesive is the most widely used, the amount of the largest one. Widely used in bookbinding, wood processing, plywood production, packaging, shoe automation, paper products processing, construction industry, electrical components, vehicle components, etc.
 
3. polyester hot melt adhesive
Polyester hot melt adhesive has excellent electrical insulation and good bonding strength, impact resistance, water resistance, cold resistance, medium resistance and elasticity are better, metal, ceramic, glass, fabric, wood, plastic rubber have more satisfactory adhesion, widely used in clothing, electrical appliances, shoes, construction and other industries.
 
4. polyamide hot melt adhesive
Polyamide hot melt adhesive has excellent heat resistance, cold resistance, electrical properties, oil resistance, chemical resistance and medium resistance, with good strength and toughness, widely used in leather, fabric, plastic, metal and other materials bonding, suitable for footwear, automotive, civil construction and furniture industries.
 
5. polyurethane hot melt adhesive
Polyurethane hot melt adhesive is often used to bond materials such as fabric, metal and glass, and is used in construction, automobile, mechanical and electrical, packaging and other fields, especially suitable for automatic bonding production lines such as automobile and construction.
 
Classification of 2. by use:
1. hot melt adhesive for building
In the construction industry, hot melt adhesives are mainly used for structure and decoration, such as cork plywood, laminated wood, plastic flooring, wallpaper and other insulation, isolation, decorative panels and non-stressed components. The use of hot melt adhesives in buildings can not only provide building quality, increase beauty and comfort, but also improve the construction process. At present, the largest hot melt adhesives for construction mainly include polyvinyl acetate esters, polyacrylic resins and polyvinyl alcohols.
 
2. Hot melt adhesive for packaging
As the coat of goods, packaging and printing has become an important factor affecting the competitiveness of goods, people have higher and higher requirements, not only low cost, durable, but also beautiful and generous, can stimulate and attract consumers, but also requires anti-counterfeiting function. Packaging with hot melt adhesive to EVA, polyester, polyamide, polyamide, polyamide, styrene block copolymer hot melt adhesive as the main varieties, including the largest amount of EVA hot melt adhesive, in addition to the use of hot melt pressure sensitive adhesive.
 
 
3. Hot-melt adhesive for shoemaking
The hot melt adhesive has been applied to the shoe industry for 40 years, the technology is mature, the use is wide, and its quantity and variety are increasing. The basic requirements of hot melt adhesive for shoes are: high initial adhesion strength and durability, short curing time, good colloid flexibility, bending resistance, heat resistance, oil resistance, water resistance, cold resistance and chemical resistance. Shoemaking hot melt adhesives are mainly ethylene-vinyl acetate copolymers, polyesters, polyamides, polyethylene and polyurethane and other hot melt adhesives, of which the first three are used more.
 
4. hot melt adhesive for textile
Adhesives are an important part of textile auxiliaries, and the purpose of using adhesives in the textile industry is to improve the appearance quality and performance. At present, the hot melt adhesives commonly used in textile printing and dyeing are ethylene-vinyl acetate copolymers, polyamides, polyurethanes, etc., as well as polyester, polyethylene, polypropylene and other types of hot melt adhesives. Mainly used for garment bonding (including: lining paste, collar, cuffs, skirt or pants waist, inner core and fabric, zipper, decorative pattern, etc.), carpet back glue, fabric flocking, non-woven fabric manufacturing.
 
5. Hot melt adhesive for electronic and electrical appliances
The rapid development of the electronic industry for bonding technology put forward many new issues to be solved, the electrical insulation of the adhesive, temperature resistance, corrosion resistance, resistance to moisture and heat aging and other aspects of the increasingly high requirements. Hot melt adhesive for electronic industry has the characteristics of high softening point, narrow melting range, high bonding strength, moderate viscosity, excellent electrical properties, good toughness and flame retardant. Hot melt adhesives for electronic industry are mainly hot melt adhesives such as polyester and polyamide.
 
6. Hot melt adhesive for automobile
As an adhesive for automobiles, its performance must not only meet the requirements of automobile use and life, but also be suitable for the manufacturability of mass flow production. It must have suitable physical and chemical properties and good construction performance. Including storage stability and transportation safety, hot melt adhesives have certain advantages on the one hand. It is mainly used for the bonding of automobile roof, the bonding of automobile interior and exterior decoration, etc. It is mainly used for polyester and polyamide hot melt adhesive.
 
7. hot melt adhesive for medical use
The hot melt adhesive used in medical treatment is mainly hot melt pressure sensitive adhesive, which is used for wound coverage, detector fixation, drug delivery carrier and surgical zipper and skin adhesion. This hot melt adhesive must have good adhesion to all kinds of skin. The adhesive is easy to remove, there will be no residue, will not harm the skin, and will not cause skin allergies.
