The heat resistance of polyester, polyimide (Kapton), ceramics, and metal foils makes them common materials to use.

Chemical Resistance: Chemicals and solvents often found in industrial environments must be able to withstand high temperature labels. Thus, they remain intact when exposed to oils, solvents, acids, and alkalis and resist chemical degradation. Chemical environments will not affect the legibility and adherence of the labels.

UV Resistance: UV resistance is another feature of some high temperature labels, which protect them against the damaging effects of ultraviolet (UV) radiation. As a result of prolonged exposure to sunlight, UV-resistant labels prevent labels from fading, discoloring, and deteriorating.

Abrasion Resistance: When labels are handled, transported, and used at high temperatures, they are often subjected to mechanical abrasion. Thus, they are designed to withstand abrasion, maintain legibility, and adhere to surfaces even under the most extreme conditions. In addition to preserving critical information, this property also helps ensure that the label will remain readable for many years to come.

Adhesive Properties: Despite extreme heat conditions, high temperature labels require strong adhesives to ensure secure bonding. Specifically formulated adhesives protect labels from peeling, lifting, or falling off over time even at elevated temperatures. These adhesives can also take into account environmental conditions, chemicals, and moisture that may compromise adhesion.

Durability: The durable and long-lasting nature of high temperature labels allows them to withstand harsh environmental conditions and maintain performance for a long period of time. For as long as the labeled item or component exists, critical information will remain intact and legible thanks to their resistance to tearing, puncturing, and other forms of damage.

Printability: The labels designed for high temperatures are often printed with thermal transfer or other methods that are compatible with materials that are heat-resistant. It enables variable data to be printed directly on labels, such as serial numbers and barcodes. For high temperature labels to be readable and durable, the print quality and durability of the information must be considered.
