What common chemicals does PET thermosensitive silver paper have corrosion resistance to?

PET thermosensitive silver paper has strong corrosion resistance to various common chemicals. The following is a specific analysis of its corrosion resistance:

Overview of corrosion resistance

PET thermosensitive silver paper is made of polyethylene terephthalate (PET) as the substrate, and after special treatment, the surface presents a silver like luster. Due to the stable chemical properties of PET material itself, PET thermosensitive silver paper also exhibits strong chemical corrosion resistance.

Specific corrosion-resistant chemicals

Acid substances: PET thermosensitive silver paper can resist the erosion of various acid substances, such as common inorganic acids (such as hydrochloric acid, sulfuric acid, etc.) and organic acids (such as acetic acid, citric acid, etc.). This allows it to maintain the clarity and integrity of the label even in acidic environments.

Alkaline substances: Similarly, PET thermosensitive silver paper also has strong corrosion resistance to alkaline substances. Whether it is strong alkali (such as sodium hydroxide, potassium hydroxide, etc.) or weak alkali (such as ammonia water, etc.), PET thermosensitive silver paper can resist its erosion to a certain extent.

Salt substances: Salt substances are usually less corrosive to label materials, but PET thermosensitive silver paper still exhibits good salt corrosion resistance. This allows it to remain stable in high salt environments such as marine environments and food processing.

Organic solvents: Some organic solvents may cause corrosion to label materials, but PET thermosensitive silver paper has strong corrosion resistance to common organic solvents such as alcohol, gasoline, diesel, acetone, isopropanol, etc. This allows it to maintain good performance in application scenarios that require contact with these solvents.

Application scenarios

Due to its corrosion resistance, PET thermosensitive silver paper is widely used in various fields such as labels, nameplates, and electronic device identification that require resistance to chemical erosion. For example, in industries such as chemical, pharmaceutical, and food processing, PET thermosensitive silver paper can ensure that labels remain clear and readable even in harsh chemical environments.

In summary, PET thermosensitive silver paper has strong corrosion resistance to various common chemicals, which makes it widely applicable in various scenarios that require resistance to chemical erosion.
