PI Film is widely used in many fields for its excellent performance, and its resistance to chemicals is also one of the focuses of people's attention.
PI Film has excellent chemical corrosion resistance and can resist the erosion of a variety of chemicals. First of all, it shows strong tolerance to most organic solvents. Common organic solvents such as acetone, ethanol, toluene, etc., are generally difficult to cause obvious damage to PI Film. This allows PI Film to maintain stable performance in environments where it needs to contact organic solvents, such as chemical production, laboratories, etc.
PI Film also has a certain resistance to acids and alkalis. Strong acids such as sulfuric acid, hydrochloric acid and strong alkalis such as sodium hydroxide within a certain concentration range are difficult to cause serious corrosion to the film in a short time. However, long-term contact with high concentrations of strong acids and alkalis may gradually affect its performance.
In addition, PI Film also has good resistance to oxidants. Oxidants such as hydrogen peroxide are not easy to cause obvious chemical changes in the film under normal use conditions.
In practical applications, PI Film in the electronics industry can resist various chemicals that may be exposed to electronic components during production and use, such as flux, cleaning agents, etc. In the aerospace field, it can withstand chemical corrosion in extreme environments, such as chemical changes that may be caused by ozone in the sky and cosmic radiation.
However, although PI Film is resistant to many chemicals, it is not completely invincible. In some special chemical environments, such as long-term and high-concentration effects of highly corrosive chemicals, the film may degrade or even be damaged.
In short, PI Film can resist corrosion from most organic solvents, certain concentrations of acids and alkalis, and oxidants. However, in specific applications, the chemical corrosion resistance of the film needs to be comprehensively considered according to the actual chemical environment and usage requirements to ensure that it can function stably and long-term.
