Is the heat-resistant temperature of hot melt adhesive pellets the use temperature?

The use temperature of hot melt particles is often mistaken as the upper limit of the temperature that can be tolerated, but as long as the parameter data is seen, there is only one parameter value for high temperature resistance, and the temperature range is the value. That is to say, hot-melt rubber particles can usually exert their properties in a corresponding temperature range, and high temperature resistance refers to the highest temperature value that the rubber particles can withstand at high temperatures to maintain a solid state.

The temperature value of the high temperature resistance of each hot melt adhesive is not the same, and it is not necessarily within the range of its use temperature. There is no direct relationship between them. Some colloidal particles begin to melt shortly after heating, but higher temperatures must be reached to exhibit superior performance, which is determined by the performance characteristics required for their production. However, there are some hot melt adhesives that are particularly affected by heat. Physical states change very quickly. Once the solid is heated, it quickly reaches a molten state and the glue is ready to use. The high temperature of the pellets is very close to the working temperature. When the hot melt adhesive is heated up rapidly, people cannot feel the softening process of the colloidal particles, which makes them change and cannot be used.

The temperature resistance of the product after gluing refers to the highest temperature that the bonding part can withstand in addition to aging. The state change of the hot melt adhesive cannot be separated from the temperature. There are several concepts derived from the temperature in different states, confusing the concept , may lead to the occurrence of rubber operation problems, after all, as long as the properties of the rubber granules do not strictly follow the big season, the hot rubber will not choose the corresponding properties in the official wrong use.
