Although EVA hot melt adhesive is an excellent solution for many industrial applications, it requires careful control of the high temperature during the process to avoid smoke problems. When hot melt adhesives are heated, they inevitably release some smoke. That is the odor detected while working near the hot melt nozzle. Although some smoke is normal, excessive smoke indicates a problem with your process and requires attention.
Our team has seen examples of hot melt adhesive smoking and provided some tips on how to make adjustments to reduce the amount of smoke.

To prevent hot melt adhesive from smoking, please check your various hot melt adhesive process parameters:
Temperature:The temperature of the hot melt gun or glue coating equipment is crucial. When it is too low, the adhesive cannot melt and flow properly. Too hot, the adhesive will become too thin and release unpleasant and irritating smoke. In some cases, burnt adhesive can cause the final glue to change color and may also lead to carbonization. Adjust the temperature settings based on the manufacturer’s specifications for the hot melt equipment and the temperature recommendations for the specific adhesive you are using.
Coating equipmentCleanliness of work area:Adhesive residues near coating equipment, coating heads, and work areas can cause adhesive problems and smoke.. Burning and dried adhesives are more prone to smoking than fresh, unmelted hot melt adhesives. The accumulation of used dry adhesive on the application equipment is a common source of smoke.

People have always been confused about the softening point and temperature resistance of hot melt adhesive. Some customers even asked what the melting point of hot melt adhesive is? Now Sunlife hot melt adhesive will answer from a professional perspective, with a detailed understanding of the differences in melting point, softening point, and temperature resistance. […]
In book binding with copperplate paper as the inner page, due to the thin film covering the surface of copperplate paper, there is a high demand for the adhesive used. It is difficult for people to bind books and periodicals with white glue in order to make them more firmly attached to copperplate paper. After […]
Conclusion: Complianthot melt adhesiveParticles are basically non-toxic at room temperature, and the risks mainly lie in “high-temperature melting” and “ingestion” Conventional EVA and APAO based hot melt adhesive particles are 100% solid content, solvent-free bulk adhesives that are stable at room temperature, non-volatile, and safe for daily contact and storage. What really needs to be […]
On bound bookshot melt adhesiveTo remove it, the correct approach isFirst, control the temperature to soften, then mechanically separate, and finally clean the residual glueUsing a mild heat source of 60-80 ℃ to soften the adhesive layer and peel it off as a whole is more secure than any forced tearing or chemical pesticides. Unfortunately, […]
