Does fluoropolymer, which has excellent chemical resistance, dissolve in hydrochloric acid?
Fluororesin is a material that exhibits excellent chemical resistance to almost all chemicals. Hydrochloric acid is a strong acid that can dissolve many metals, but fluororesin does not dissolve in hydrochloric acid. Fluororesin is generally not affected by hydrochloric acid on its own; however, caution is necessary when used as linings or coatings intended to protect metals. Hydrochloric acid can penetrate fluororesin linings or coatings depending on its concentration and temperature. This penetration can lead to blistering, which impairs corrosion resistance. Additionally, thin fluororesin coatings may leave pinholes, allowing hydrochloric acid to infiltrate and directly corrode the substrate. If you want to protect metals from chemical solutions like hydrochloric acid, please consult us when considering measures involving fluororesin.
