What is hot melt adhesive?

Hot melt adhesive is a modern synthetic resin and a pure solid adhesive. Hot melt adhesive is a thermoplastic material composed of stabilizer, additive, pigment and polymer, which is sold in the form of solid, cylindrical rod or particle. The rod is melted and coated with a hot melt spray gun or sprayer. Hot melt adhesives come in many forms. It can be seen from the substances contained in hot melt adhesive that it is solvent-free, non-toxic and pollution-free, so it has great development potential.

1: What is a hot melt adhesive film?

Simply understood, it is adhesive. Adhesives for composite bonding of products. It takes a certain temperature to produce viscosity.

2. What material can the hot melt adhesive film stick to?

What material can hot melt adhesive stick to? Let's first distinguish the material of hot melt adhesive film. According to different materials, we are looking for hot melt adhesive films to adhere to those materials. According to experience, Bian Xiao summarized the main features of various hot melt adhesive films as follows:

(1)eva hot melt adhesive: It has low use temperature, low cost, and a wide range of bonding materials, but it has poor water resistance, high temperature resistance and low bonding strength. Mainly bonding eva foam, leather, wall covering, non-woven fabric, metal, wood and so on;

(2)tpu hot melt adhesive: It has a good effect on cloth and leather glue, and is widely used in clothing and shoe materials. Good washing resistance, relatively good high temperature resistance, soft feel, but high cost. Most products are prone to yellowing.

(3)pes hot melt adhesive: it has the characteristics of washing resistance and dry cleaning resistance, and has high bonding strength; Suitable for bonding metal, conductive cloth, wood, foam, textiles, etc.

(4)pa hot melt adhesive: water and solvent resistant, good weather resistance, and good bonding effect on fabric materials. Widely used in automobile interiors, shoes, bags, home textiles and so on.

(5)po hot melt adhesive: It has good water resistance, weather resistance and solvent resistance, and some products have good temperature resistance, and the bonding temperature is generally high. Suitable for metal bonding;
