High-Temperature Label Testing Report
Sticker labels play a crucial role in various industries, providing important information and enhancing product branding. However, in certain applications, such as those exposed to high temperatures, the performance of sticker labels can be compromised. In this report, we present the findings of our high-temperature label testing, focusing on the durability and legibility of labels under extreme heat conditions.
Testing Methodology
To evaluate the performance of sticker labels under high-temperature conditions, we conducted a series of tests using a controlled environment chamber. The labels were subjected to temperatures ranging from 70°C to 200°C, simulating extreme conditions encountered in industries like automotive, aerospace, and manufacturing.
We selected a variety of sticker labels commonly used in these industries, including polyester, polyimide, and vinyl labels. The labels were applied to different surfaces, such as metal, plastic, and glass, to assess their adhesion and durability.
Results
After subjecting the sticker labels to high temperatures, we observed the following:
1. Adhesion: The adhesion of the labels varied depending on the material and surface. Polyester labels exhibited excellent adhesion on metal surfaces, even at temperatures exceeding 150°C. Polyimide labels showed good adhesion on plastic surfaces, but their performance deteriorated at temperatures above 180°C. Vinyl labels, on the other hand, had limited adhesion on glass surfaces, especially at temperatures above 120°C.
2. Durability: The durability of the labels was assessed by measuring their resistance to heat-induced deformation, fading, and peeling. Polyester labels demonstrated superior durability, maintaining their shape and legibility even at temperatures as high as 200°C. Polyimide labels showed moderate durability, with slight deformation and fading observed at temperatures above 160°C. Vinyl labels exhibited poor durability, with significant deformation and fading occurring at temperatures exceeding 100°C.
Discussion
Based on our testing, it is evident that the choice of sticker label material is crucial when considering high-temperature applications. Polyester labels prove to be the most reliable option, offering excellent adhesion and durability across a wide temperature range. However, in specific cases where plastic surfaces are involved, polyimide labels may be a suitable alternative.
It is important to note that the performance of sticker labels under high temperatures can also be influenced by factors such as exposure duration, humidity, and chemical exposure. Further research and testing are recommended to assess these additional variables and ensure optimal label performance in real-world conditions.
Conclusion
Our high-temperature label testing report highlights the importance of selecting the right sticker label for applications exposed to extreme heat. Polyester labels emerge as the top choice, demonstrating excellent adhesion and durability at temperatures up to 200°C. Polyimide labels offer a viable option for specific applications involving plastic surfaces. These findings enable industries to make informed decisions when choosing sticker labels for high-temperature environments, ensuring product integrity and legibility.
