What is the chemical stability of PET silver paper?

PET silver paper has good chemical stability. The following is a detailed analysis of its chemical stability:

Chemical stability

1. Chemical resistance:

PET silver paper has good resistance to most organic solvents, acids and bases, and other chemical substances. This is due to the molecular chain structure of PET plastic, which is tightly arranged and not easily penetrated by chemicals, thereby enhancing its chemical stability.

2. Hydrolysis resistance:

Although PET contains ester based structures, hydrolysis reactions are difficult to occur at room temperature and pressure. PET will only undergo hydrolysis reaction under high temperature, high pressure, acidic or alkaline environment, but in this case, the hydrolysis reaction is relatively slow and will not quickly lead to a decrease in material properties.

Precautions in practical applications

Although PET silver paper has good chemical stability, the following points still need to be noted in practical applications:

1. Avoid prolonged exposure to strong acids and bases:

Although PET silver paper has a certain resistance to acid and alkali, prolonged exposure to strong acids, alkalis, and other chemicals may still cause some damage to it.

2. Pay attention to the usage environment:

The chemical stability of PET silver paper may be affected in special environments such as high temperature and high pressure. Therefore, it is necessary to pay attention to factors such as environmental temperature and pressure when using.

In summary, PET silver paper has excellent chemical stability, can resist the erosion of various chemical substances, and maintain good hydrolysis performance at room temperature and pressure. However, in practical applications, it is still necessary to avoid prolonged exposure to strong acids, bases, and other chemical substances, and to pay attention to the environmental conditions of use.
