Nylon Hot Melt Adhesive Film Heat Resistance
Jul 04, 2025
The temperature resistance of Nylon Hot Melt Adhesive Film is a key indicator to measure its quality and scope of application, which is restricted by many factors.
Basic temperature resistance range: Nylon hot melt adhesive film usually has good initial temperature resistance and can generally maintain relatively stable physical properties in the range of -20℃ to 120℃. In low temperature environments, such as close to -20℃, the flexibility of the film will decrease, but as long as it is not lower than its brittle temperature, it can still maintain a certain degree of viscosity and structural stability, and will not easily crack and affect its use.
Effect of high temperature: When the temperature exceeds 120℃, the molecular chain activity of nylon hot melt adhesive film intensifies. In the range of 120℃ - 150℃, slight softening may occur and the viscosity begins to fluctuate, which may lead to a decrease in the adhesion between it and the adherend. If the temperature continues to rise to above 150℃, the film will soften significantly or even melt, and the molecular structure will gradually be destroyed. At this time, the adhesive performance of the film will decline significantly and cannot function normally.
Influencing factors: The heat resistance is also closely related to the formulation of the film. After special modification and the addition of high temperature resistant additives, the upper temperature limit of the nylon hot melt film can be improved to a certain extent, and the performance can be kept stable in a higher temperature environment. In addition, if it is in a high temperature environment for a long time, even if it does not reach its melting point, the film will gradually deteriorate due to heat aging, and the performance will continue to decline.
Therefore, in practical applications, it is necessary to reasonably select and use nylon hot melt adhesive film according to the specific temperature environment to ensure that it can meet the use requirements under different temperature conditions.
