Under normal temp., PVF2 has a fine corrosion resistance to many organic solvents like halogen, halogenated hydrocarbon, strong oxidant, boiling acid and alkali; UHMWPE has a fine corrosion resistance to inoxidable acid (dilute sulfuric acid, nitric acid and large concen-tration hydrochloric acid, phosphorus acid, hydrofluoric acid, formic acid and acetic acid), ammonia, amine and various alkali and salty solutions. Both materials can't resist the corrosion of strong oxidable acid.

在常温下，PVF2对卤素、卤代烃、强氧化剂、沸酸、碱等多种有机溶剂都有良好耐蚀性；UHMWPE对非氧化性酸(稀硫酸、硝酸及浓度较大的盐酸、磷酸、氢氟酸、甲酸、乙酸)、氨和胺及各种碱、盐溶液都有良好的耐蚀性，两种材料都不耐强氧化性酸的腐蚀。
