Chemical Resistance

ECTFE has excellent resistance to strong acids such as sulfuric, nitric, hydrochloric and hydrofluoric over a wide temperature range. ECTFE can also easily handle powder bleaching agents such as sodium hydroxide and potassium hydroxide that would stress crack PVDF. ECTFE 901 can handle strong polar solvents that would dissolve PVDF such as n-Methyl pyrrolidone and dimethyl formamide.
