Is used for hot melt adhesive industry is divided into many, more commonly used mainly has the following categories:
Fabric with hot glue
Mainly used for production, such as shape, shoes, hats. Use the hot melt adhesive clothing not only has a crisp, full of appearance quality, and the nature of the ground after washing, without pressing can wear characteristics. Use the rubber shoes, caps lightsome breathe freely, keep good type, especially for shoemaking industry, also has comfortable, reduce the advantages of shoe smelly. The purpose of hot-melt adhesive technical indicators are as follows: appearance: white or light yellow granular or powder. Melting point: 105-115 ℃, melt index: 18 to 22 g10min (160 ℃); Apparent density: 0.48 to 0.52 g/cm3. Rest Angle: 30-35 degrees; Bonding strength: acuity 1.5-2.0 kg / 25 mm; Wash resistance: 5 or more times.
Can be divided into such hot-melt adhesive polyamide (PA), polyester (PES), polyethylene (LOPE and HDPE) and polyester amide (PEA) and so on, this kind of adhesive has passed five achievements appraisal, complete national ">" research, "five-year" research project in hebei province, won the national invention, tianjin, hebei science and technology achievement award a three, won the national invention patent.
Packaging and book binding with hot glue

　　At present, food, drinks, instant noodles, cigarettes, beer, medicine and other packaging sealing, mostly use hot sol by sealing machine to complete. Book binding industry have been swept away the old line, binding, use hot glue stick process, not only improve the quality of bookbinding, more important is greatly speed up the binding, which use hot sol technical indicators are as follows: packing books in appearance White granular Buff flake melting point (70-84 ℃), 65-78 viscosity hardness, 2500-3500, 5500-2500, 78-82, 65-78
The curing speed 3-5 0 to 20
Hot-melt pressure sensitive adhesive
Mainly used for women's sanitary napkin, diaper, bed pad, senile incontinence supplies such as shame. Especially the latter, along with our country aging of population structure. The next older incontinence supplies will increase rapidly. The use hot sol of technical indicators are as follows: type: white or light yellow block viscoelastic, solid; Melting point: 80-90 ℃; Bonding strength: 2.0 to 2.51 g / 25 mm;
Health requirements: tasteless, non-toxic, do not stimulate the skin.
Multi-purpose solvent thermal sol
In many products, such as thermal transfer printing, sealing liquid crystal materials, wallpaper anti-counterfeiting grade, calligraphy and painting paper, computer printing, food, wire and cable production date type code is the performance of the application of hot-melt adhesive, but cannot use the existing granule or powder form, not in a suitable solvent is made under the existence of liquid, the coating on a substrate, thin and uniform film, may be used in process after the production. Due to the different kinds of solute (hot glue), multiple applications can be made of the solvent thermal sol.
Furniture edge banding hot sol
Are countries with a deficiency of timber in our country, in addition to a small amount of high-grade furniture use real wood, furniture mostly usually use fiber board, wood shavings or sawdust plate production, and furniture plate edge parts must use hot sol to adhesive sealing side materials, increase the aesthetic feeling, like solid wood furniture. It USES the technical index of the hot-melt adhesive is as follows: appearance: white is slightly yellow granular or stick. Melting point: 70-84 ℃; Viscosity: 45000-75000 (180 ℃).
The relative hardness: 70-80%; Curing speed: 8 to 12 seconds.
Thermoplastic powder coatings
Main polyethylene (CDPE) and polyvinyl chloride (PVC) of two kinds of powder coatings. Used in the cages with fish, the road guardrail, basked themselves, rack, refrigerator insulation, fan cover, etc. According to the need to make all sorts of color, coating on the surface of metal products protection and decoration effect. Performance: LOPE coating PVC coating color: according to the purpose in accordance with the selected use selected size: 80-120 mesh, 80-120 mesh metal adhesion: good
Generic model: the OSD - 150, 5015, 1116
Hot melt adhesive film
Hot melt adhesive film is mainly divided into two major categories of thermoplastic and thermosetting, mainly used for electronic product nameplate, plastics, hardware, mobile phone window frames and front
