Hot melt adhesive is a plasticity adhesive products, hot melt adhesive in a certain temperature range its physical state changes with temperature changes, however the chemical properties is the same, hot melt adhesive particles non-toxic and tasteless, belongs to environmentally friendly glue products,can be used for various industries packaging aspects.
So how do we choose the right hot melt adhesive particles?
From the color, temperature, operations methods and many other aspects to consider. First we say gule color requirements should be different. Hot melt adhesive on the object appearance treatment not strict than other adhesive, but the objects appearance dust, oil should also be properly handled, in order to make hot melt adhesive particles better display bonding effect.
Fast operation is a major feature of hot melt adhesive. Hot melt adhesive work time is generally about 15 seconds, with the modern mode production – assembly line extensive use, for hot melt adhesive working time is require more and more shorter.
Another is the anti-temperature, hot melt adhesive is more sensitive to the temperature. When the temperature reaches a certain level hot melt adhesive begins to soften, below a certain temperature, hot melt adhesive will become brittle, so select hot melt adhesive must take full account product located temperature changes. If the temperature is too high, then you can choose high temperature hot melt adhesive.
Hot melt adhesives particles are generally used hot melt machine through the heat melting hot melt adhesive, after melting glue is becoming liquid. Through hot melt hose and hot-melt adhesive gun, delivered to the adhesive appearance,when hot melt adhesive is cooling down,that is, completed the bonding.
