?A: PC material is corrosion resistant. ?

PC material, that is, polycarbonate, has good chemical stability and can withstand the corrosion of most chemicals. It has 

good corrosion resistance to weak acids, including citric acid, acetic acid, etc., but in high concentrations or strong acid 

environments, such as nitric acid and concentrated sulfuric acid, PC material will corrode and dissolve. Similarly, PC material 

shows good stability in neutral and weakly alkaline environments, such as weakly alkaline substances such as ammonia, 

but in strong alkali solutions with higher concentrations, such as sodium hydroxide concentrated solutions, it will cause 

certain corrosion to PC materials. Nevertheless, PC materials are widely used in many applications because of their excellent 

corrosion resistance. In order to ensure the performance of PC materials under specific conditions, it is recommended to 

test chemical resistance before practical application. In addition, there are also modified PC materials, such as enhanced 

PC and chemically improved PC, which have greater acid and alkali resistance and can be used in a wider range of chemical 

environments ?
