Hot melt adhesive is a plastic adhesive that usually consists of a synthetic resin or polymer. Its degree of temperature resistance varies depending on the type of product and technical parameters. Most hot melt adhesives are temperature resistant in the range of 120°C to 180°C, and some special types of hot melt adhesives can withstand higher temperatures.
The temperature resistance of hot melt adhesives depends on their composition, production process and formulation design. In general, hot melt adhesives will gradually soften and lose their viscosity when heated, and will gradually solidify and regain their viscosity when the temperature is lowered. Therefore, hot melt adhesives need to be kept within the proper temperature range during processing and storage to ensure their stickiness and durability.
When choosing a hot melt adhesive, it is necessary to choose the appropriate temperature resistance range according to the specific application scenario and use environment. For example, for the bonding of products such as shoes, leather goods, and automotive parts, which need to withstand high temperatures, hot melt adhesives that can withstand higher temperatures are required. For products that need to withstand lower temperatures, such as food packaging and medical and hygiene products, hot melt adhesives that can maintain their stickiness at low temperatures are required.
In short, the temperature resistance range of hot melt adhesive depends on its composition, production process and formula design, and it is necessary to select the appropriate temperature resistance range according to the specific application scenario and use environment when choosing.
