Generally,the application areas for PVDF, Polypropylene,and Polyethylene heat exchangers willbe the same as those for SYGEF-PVDF,Polypropylene, and Polyethylene pipingsystems. The following guidelines are usedwhen selecting the appropriate heat exchangerfor a specific application: 1) For steam heatingof inorganic and organic acids commonly usedin plating (chrome, phosphoric, nickel, sulfuric,hydrochloric, nitric, hydrofluoric etc.) usePVDF. 2) For aqueous salt solutions and alkalisolutions, use Polypropylene, or Polyethylene.3) For any heating application utilizing steam asthe heating medium, PVDF must be used. PVDFcan be used up to 281°F (35 PSIG saturatedsteam). 4) For cooling sulfuric acid solutions,Polypropylene or Polyethylene should be usedas it is most economical.MECHANICAL STRENGTHPVDFPPPEMax.
