Is hot melt adhesive a dangerous chemical?

Hot melt adhesive formulations contain no hazardous chemicals. Although they are chemicals, they are not dangerous! According to the definition of hazardous chemicals, it refers to highly toxic chemicals with toxic, corrosive, explosive, flammable and combustion-supporting properties, which are harmful to human body, facilities and the environment. We analyzed hot melt adhesives from the above aspects to see if they are dangerous chemicals.

 

Hot melt adhesive is not a dangerous chemical, it is a green product.

 

poison

 

Hot melt adhesives do not release harmful fumes and odors at normal or high temperatures, not to mention the health hazards of toxic drugs. The carbide of the hot melt adhesive is environmentally friendly to the natural environment and does not pollute the environment even if it reaches a carbonized state. Once a hot melt adhesive is made, it does not degrade and there are no degradable hot melt adhesives on the market. However, this does not mean that throwing it in the landfill will pollute nature.

 

corrosion

 

Corrosion is very remote for hot melt adhesives, there are other materials that corrode hot melt adhesives, and there is no hot melt adhesive to corrode adherents. There are no materials in the composition of the hot melt adhesive that can corrode anything. Conversely, in harsh environments, the polymer material can be attacked by other harmful substances, causing its performance to gradually diminish. As for the plastic material, the deformation of the substrate is not caused by the corrosion of the hot melt adhesive of the substrate, but because the temperature of the glue is relatively high, the substrate cannot withstand such high temperature. deformation.

 

explode

 

Hot melt adhesive doesn't even burn, explosions are out of the question. The most common and most visible changes in hot melt adhesives are liquefaction and curing. Although the application of hot melt adhesive is unconventional, its performance can only be greatly reduced, resulting in poor bonding effect. The explosion also requires a substance that causes the explosion, and there is obviously no such substance in the composition of the hot melt adhesive, so it is impossible for the hot melt adhesive to explode on its own.

 

combustion

 

As long as the hot melt adhesive produced by conventional formulation does not burn, it will melt. Combustion only transfers temperature to the hot melt adhesive, and hot melt adhesives only reflect physical changes caused by temperature. If you burn yourself, it may be that the hot melt has gone bad, or there is too much other material on the surface. An open flame ignites these impurities and looks like hot glue burning. Otherwise, you can burn it for 24 hours and the hotmelt will still stubbornly stick to its molten state.

 

Flame Retardant

How can non-burnable hot melt glue help burn? In small or large amounts, even if gasoline is splashed on it, it will just burn itself, and the hot glue will melt when heated. When the gasoline burns out, it is impossible for the hot melt adhesive to continue to burn, regardless of the state. No one claims that hot melt adhesives will support combustion.

 

Hot melt adhesive is an environmentally friendly chemical, and although it cannot be eaten in the stomach, chewing it in the mouth does not pose a health hazard to the human body. It can be seen that hot melt adhesive is environmentally friendly enough.
