Is PC (polycarbonate) material corrosion-resistant?

 

Answer: Yes, PC is corrosion-resistant. PC, or polycarbonate, has good chemical stability and can withstand the corrosion of most chemicals. It has good resistance to weak acids, including citric acid and acetic acid, but in high-concentration or strong acid environments, such as nitric acid and concentrated sulfuric acid, PC will corrode and dissolve. Similarly, PC exhibits good stability in neutral and weakly alkaline environments, such as weakly alkaline substances like ammonia, but in high-concentration strong alkaline solutions, such as concentrated sodium hydroxide solutions, PC will corrode to some extent. Nevertheless, PC is widely used in many applications due to its excellent corrosion resistance. To ensure the performance of PC under specific conditions, it is recommended to conduct chemical resistance testing before actual application. In addition, there are modified PC materials, such as reinforced PC and chemically stable PC, which have stronger acid and alkali resistance and can be used in a wider range of chemical environments.
