Introduction to hot melt adhesive
Hot melt adhesive is short for hot melt adhesive, is an important category of adhesive industry, with 100% solid content, no solvent, environmental protection, non-toxic, fast curing characteristics, usually refers to the solid state at room temperature, when heated to a certain temperature will melt into viscous liquid, coating, wetting the adhesive, after pressing, cooling to room temperature, The adhesive completes the bonding in a few seconds. Therefore, it is widely used in medical protective supplies, household hygiene products, automatic packaging, tape labels, electronic appliances, automotive interior decoration and other industries.
Hot melt adhesive application case
1. Gluing of nose bridge strip of mask:
There are many types of masks, but they all have nasal bridge strips to fix the mask on the bridge of the nose, effectively isolating the virus and ensuring smooth exhalation. The bridge of the nose is mostly thin aluminum strips, which have some strength, but are also easy to bend, making it easy to wear masks. The fixing of the bridge of the nose, most of them are glued with hot melt adhesive, hot melt adhesive first composite on the bridge of the nose, and then hot press paste on the production line. Cheng Ming M-638E is used in the adhesion of nose bridge because of its environmental protection, non-toxic, white and transparent, low odor, strong adhesion, fast curing and high production efficiency.
2. disposable protective clothing material composite:
Hot melt adhesive used in PE breathable film and water-resistant non-woven fabric composite, the bonding strength to achieve both sides of the broken wood effect, hot melt adhesive is usually used SBC structural adhesive, coated gram weight 1.8-4.0g/m2; Some of the more demanding medical protective clothing will use PUR hot melt adhesive. Hot melt adhesive products because of environmental protection, non-toxic, fast bonding, strong bonding, and used in this kind of material composite.
3, disposable protective mattress material composite:
Protective mattress compound and protective clothing are similar, hot melt adhesive used in PE breathable film and water-repellent non-woven fabric compound, requires bonding strength to achieve both sides of the broken wood effect, hot melt adhesive is usually used SBC structural adhesive, coated gram weight 1.8-4.4g /m2; Chengming's CM929TA5 and other hot melt adhesive products are used in this kind of material composite because of their environmental protection, non-toxic, fast bonding and strong adhesion.
