Is hot melt rubber flammable?

Are hot melt particles flammableAlthough hot melt colloidal particles are chemical products, but even if the open flame burns, it will only carbonize in the end, it will not burn itself, so hot melt colloidal particles are not flammable.General hot melt adhesive particles, we all know that it is synthesized by matrix resin, viscosifier, plasticizer, antioxidant, fillers and other conventional raw materials, just look at some of the raw materials are combustible, but after mutual chemical reaction can make their synthesis become non-flammable. Hot melt particles are sensitive to temperature. Indeed, they only accept changes in temperature. When the hot melt adhesive meets an open flame, the flame continuously transfers the temperature to the hot melt adhesive, and the former constantly changes with the temperature and becomes thinner from melting. If you keep raising the temperature, the glue will change from being black and hard to coke. In the whole process, the hot melt particles changed from solid to liquid and from liquid to solid, although their properties changed constantly, they showed no flammability.Pollutants on the surface of the hot melt particles burn up, giving the illusion that the particles themselves are non-combustible. Some users are more careless, the unused hot melt particles have been exposed to the production shop particles with more pollutants, the surface of the particles stuck to the pollutants is difficult to clean up. During production, pollutants are carried into the rubber furnace together. The temperature in the rubber furnace is constantly rising. While the hot melt particles are melting, the pollutants are also burning continuously. Users who do not know the situation still think that the hot melt glue is burning.Hot melt glue to get living space in so many industries, the raw material formula to its performance adjustment ability control ability is very strong, do not rule out in some industries used in the hot melt particles are flammable, but in the conventional, mature industry, is temporarily not encountered with combustible hot melt particles.
