Can a 46.4% ethylene glycol aqueous solution corrode fluoroplastics? If a pump is used for transportation, what type of flow-through components are used? Is a magnetic pump or a centrifugal pump better?
(1) Polytetrafluoroethylene (PTFE) exhibits good corrosion resistance under conditions of any concentration of ethylene glycol and temperatures ranging from 60 to 240°C; the degree of corrosion is mild or none； (2) Polyperfluoroethylenepropylene (FEP, F46) exhibits good corrosion resistance under conditions of any concentration of ethylene glycol and temperatures ranging from 60 to 200°C; corrosion is mild or absent ； (3) Polyvinylidene fluoride (PVDF2) exhibits good corrosion resistance under conditions of any concentration of ethylene glycol and temperatures ranging from 20 to 140°C, with mild corrosion or no corrosion at all ； (4) Polytrifluorochloroethylene (PCTFE) exhibits good corrosion resistance under conditions of any concentration of ethylene glycol and temperatures ranging from 25 to 175°C, with mild corrosion or no corrosion at all.
