What is hot melt double-sided adhesive?

1. Customer background (industry background, company nature, regional characteristics)

The hot melt double-sided adhesive that everyone is familiar with is made of cotton paper as the base material, with hot melt adhesive coated on both sides, and released with white silicone-treated isolation paper. This hot melt double-sided adhesive is essentially the same as hot melt adhesive film. The common large roll of hot melt adhesive film is cut into small rolls by a machine to become hot melt double-sided adhesive, which is actually a "small version" of hot melt adhesive web film.

Types: What are the types of hot melt double-sided adhesive?

There are many types of double-sided adhesives. There are mainly two types of hot melt double-sided adhesives.

One is the hot melt adhesive film type.

The other is the same material as the hot melt web film, with a shape like silk thread interweaving, and no release paper.

Advantages: What are the advantages of hot melt double-sided adhesive in material composites?

Compared with the common general specification double-sided adhesive, hot melt double-sided adhesive has long-lasting adhesion and good water resistance, steam resistance, temperature resistance, UV resistance, good weather resistance, strong adhesion, double-sided bonding, easy to tear, clean use and other characteristics, suitable for many crafts or DIY items bonding.

Use: How to use hot melt double-sided adhesive?

Hot melt double-sided adhesive is melted by heating and then used for bonding. For example, when using hot melt double-sided adhesive for handicrafts or DIY, you can use an electric iron to heat it. If it is used in large quantities or factory types, there will be special supporting equipment or production lines.

Material: What is the current mainstream material of hot melt double-sided adhesive in the market?

There are four main materials for hot melt double-sided adhesive, namely PA based hot melt double-sided adhesive, PES based hot melt double-sided adhesive, TPU based hot melt double-sided adhesive, and EVA hot melt double-sided adhesive. Among them, PA material occupies the mainstream high-end market, mainly because the PA based hot melt double-sided adhesive has good comprehensive performance, and EVA occupies the vast majority of the market in low-end applications.

PA based Hot melt adhesive - Use of PA in this application of hot melt double side adhesive:

PA is relatively popular in the hot melt double-sided adhesive industry because its performance in all aspects is better than other materials and it is non-toxic. Therefore, PA hot melt adhesive is the first choice for adhesive tapes in many high-end applications. At the same time, in this application, customers use PA in two processes: direct hot melt to make tapes and solvent dissolution and then production. From the current information, the direct hot melt and film making method may cause some molecular chains to be damaged, the cohesion to decrease, and the strength of the film to decrease. It should be noted that there is no feedback in this regard after dissolution.
