Does the widely used hot melt adhesive formula contain dangerous chemicals? Perhaps most people who do not understand these 1 industries will have doubts in this regard. Although hot melt adhesive is a chemical product, it is not dangerous! It is the 1 kind of environmentally friendly green adhesive. The definition of dangerous chemicals refers to toxic, explosive combustion and with corrosion, combustion of flammable and explosive toxic chemicals. Not only harmful to the environment but also to human health! So hot melt adhesive in these areas have one or two points? Can be said to be dangerous chemicals? 1. Poisonous pollution? In fact, hot melt adhesive no matter at room temperature or high temperature will not produce harmful smoke gas, it is not highly toxic to human health can not be said to be harmful. Although hot melt adhesive cannot be degraded, it will not cause pollution to the environment. It is environmentally friendly and green and has passed international environmental protection certification. Even if it is carbonized or incinerated, it will not pollute the environment. (2) Corrosive? Hot melt adhesives are completely non-corrosive in this respect, because they do not have any corrosive raw materials. Some substrate deformation caused by hot melt adhesive when bonding the substrate is not caused by corrosion, but the temperature of the heated glue solution is high, and the substrate itself cannot withstand the deformation caused by this temperature. Hot melt adhesive, a high molecular polymer material, is easily eroded by other harmful substances if it is in a bad environment, resulting in reduced performance! 3 Will it explode? Hot melt adhesive belongs to thermoplastic bonding chemical products, explosion? For hot melt adhesive is completely impossible! The only change you can see is liquefaction and solidification! Heating that is melted into a liquid, cooling that is solidified. Even if we don't use it in the right way, it will only reduce the performance of the adhesive! If the product wants to have an explosive effect, it must contain flammable and explosive raw materials, and the hot melt adhesive is obviously completely absent. 4 Burning? For hot melt adhesive, combustion will only bring it to the heating temperature and melt it into liquid state. As long as it is a normal and conventional formula, the hot melt adhesive will only melt without burning. If spontaneous combustion occurs, it may be the deterioration of the hot melt adhesive or the presence of other substances on the surface, which may cause the open flame to ignite these impurities. 5, there is a possibility of combustion? Hot melt adhesive that cannot be burned is definitely impossible to have combustion-supporting effect. Even if flammable substances are directly poured on hot melt adhesive, only flammable substances will burn. However, hot melt adhesive melts into glue liquid after being heated, and hot melt adhesive will not continue to melt after flammable substances burn out. Therefore, hot melt adhesive cannot support combustion.
