There are many types of hot melt adhesives, and the commonly used hot melt adhesives mainly include PA PES, TPU, EVA, LDPE, HDPE, etc.

Hot melt adhesive is divided into two types: high temperature and low temperature, imported glue.

Hot melt adhesives are widely used in the field of clothing.

The hot melt adhesive has poor washing resistance and is an imported glue.

Hot melt adhesives are similar to EVA in terms of washability.

Hot melt adhesive is a high-temperature hot melt adhesive.

The hot melt adhesive has super adhesion when compounded with PU TPU material.

Hot Melt Adhesive Selection Criteria.

First, the color requirements of the glue should be different. If there is no special requirement for the color of the substrate itself, then the color of the glue itself will not have much effect, and the common hot melt adhesive colors are yellow, coffee, dark coffee, white, and transparent.

Second, the surface treatment of the substrate. The surface treatment of the hot melt adhesive is not as strict as that of other adhesives, but the dust and oil on the surface of the substrate should also be properly treated to make the hot melt adhesive better exert its adhesive effect.

3. Operation time. Fast work is a major feature of hot melt adhesives. The operation time of hot melt adhesive is generally about 15 seconds, with the wide application of modern production methods - assembly line, the operation time requirements for hot melt adhesive are getting shorter and shorter, such as book binding and speaker manufacturing for hot melt adhesive operation time requirements of about 5 seconds.

Fourth, temperature resistance. Hot melt adhesives are sensitive to temperature. When the temperature reaches a certain level, the hot melt adhesive begins to soften, and below a certain temperature, the hot melt adhesive will become brittle, so the selection of hot melt adhesive must fully take into account the temperature changes of the environment in which the product is located.

Fifth, stickiness. The adhesion of hot melt adhesives is divided into early adhesion and late adhesion. Only if the early tack and the later tack are consistent can the hot melt adhesive be stable with the substrate.

In the production process of hot melt adhesive, it should be guaranteed to have antioxidation, halogen, acid and alkali resistance and plasticity. Depending on the material of the substrate, the viscosity of the hot melt adhesive is also different, so different hot melt adhesives should be selected according to different materials.

1. The types of hot-melt adhesives are divided according to the form, mainly as follows: hot-melt adhesive particles, hot-melt adhesive blocks, hot-melt adhesive powder, hot-melt adhesive sticks, hot-melt adhesive strips, hot-melt adhesive films, hot-melt mesh films;

2. Hot melt adhesives are divided according to the material, mainly the following types: PA, PES, EVA, TPU, EAA and other material types.

3. The model division is not suitable, because the model is divided by each manufacturer itself, not the unified industry standard, so no.

1) Determine which type of hot melt adhesive is used in the bonding process of the material;

2) Determine the temperature resistance of the material.

3) Determine the temperature, pressure and other settings of the composite equipment.

There are three types of high-temperature hot melt adhesives: EVA type, PA type, and modified reaction type high-temperature hot melt. These three types of high-temperature hot melt adhesives have different principles:

The high-temperature hot melt adhesive only undergoes physical changes at temperature, so the phenomenon of melting and solidification is reversible. By increasing the temperature of its heating and melting, it can achieve the effect of high temperature resistance, for example, through a special formula to make it melt at 180, then its temperature resistance will naturally increase, but this improvement is limited, the melting point is increased to 180, the glue may begin to soften at 120 degrees Celsius, and the bonding performance will be greatly reduced.

The principle of high-temperature hot melt adhesive is the same as that of EVA, because the material itself has better high-temperature resistance, so it is easier to improve its melting point.

3.The principle of modified reactive high-temperature hot-melt adhesive is that after the glue is cooled and solidified, it comes into contact with air and undergoes a mild chemical reaction without shrinkage and non-volatile, so as to obtain a flexible and high-strength polyurethane colloidal polymer. By improving the quality of this polyurethane polymer, the performance of the glue can be improved in various aspects.

For example, in the case of ENIENT EG2806, polyurethane polymers improved by chemical crosslinking technology can withstand temperatures of up to 130 degrees Celsius, achieving high temperature resistance and aging resistance. The polymer colloids after this reaction not only have much greater adhesion than EVA and PA glues, but also have irreversible sensitivity to temperature, that is, the cured colloids are no longer susceptible to high temperatures, making them more reliable.

There are many well-known hot melt adhesive companies.

There are three kinds of hot melt adhesives: glue blocks, rubber particles, and glue sticks, which are not only different in terms of form and adaptation equipment, but also in terms of performance. Comparing hot melt adhesive blocks and hot melt adhesive particles, which one has better tensile strength and low temperature resistance?

Tensile force is related to cohesion, low temperature resistance is related to temperature tolerance performance and stability of molecular structure, which are the key parameters of hot melt adhesive production, with different industries to compare these data, itself is not comparable, but if you want to compare, the tensile force and low temperature resistance of the rubber block is better than that of rubber particles.

So why is the tensile strength and low temperature resistance of hot melt adhesive blocks better than those of rubber pellets? This is due to the fact that rubber is added as a raw material in the production process. Rubber can make the block more cohesive and stable in molecular structure.

Under different formulas, the differences between hot melt adhesive blocks and hot melt adhesive particles in various performance parameters are different, and some parameter rubber particles will be better than rubber blocks, which is very normal. Always, choose the right glue, in order to use good glue.

Hot melt glue blocks and hot melt glue particles, I think the effect of glue blocks will be better.

Because some of the rubber particles may be made of some small residual things, and the quality of the rubber blocks is generally better.

Let me ask the question, which is better, hot melt adhesive block or hot melt adhesive particle? I think it's better to use the rubber pellets, because they are all of the same kind, and they are all about the same.

It is better to have hot melt adhesive blocks and hot melt adhesive granules because it is easier to store.
