Â| Lining material | Main Performance | Applications |
| Teflon | 1.The most steady material in plastics which is resistibal to boiling hydrochloric acid,vitriolandqua fortis as well as strong alkali and organic impregnates.        2.Not be perfect in abrasion resistance. |
Strong corrosive mediums such as strong acid and alkali |
| PFA | Having the same abrasion resistance with PTFE. Having strong ability of load pressure resistance. |
Applicable in state of load pressure |
| F46 | 1.Have the same abrasion resistance with PTFE. 2.Resistable for low abrasion. 3.Having strong resistance to load pressure. |
  1.The same as PTFE.2.Applicable in mediums of low abrasion. |
|  Neoprene |  1.Be of good elasticity,retractility and abrasion resistance. 2.Be resistant to low aicd,alkali and salt but not for oxidation mediums. |
Water,sewage and slurry,mineral serosity of low abrasion. |
| Polyurethane | 1.Be of good abrasion resistibility. 2.Not be perfect in acid/alkali resisitance. 3.Can't be used for water mixed with organic impregnants. |
Applicable in mineral serosity,slurry and coal slurry of high abrasion. |
| Electrode material | Applications |
| Stainless steel SUS316 | Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol, chemistry,carbamide,etc |
| Stainless steel covered with tungsten carbide |
Applicable in mediums of no corrosive and low abrasion. |
|   Hastelloy B(HB) | Having strong resistance to hydrochloric acid of any consistance which is below bioling piont. Also resistable against vitriol,phosphate,hydrofluoricacid,organic acid etc which are oxidable acid,alkali and non-oxidable salt. |
| Hastelloy C(HC) | Be resistant to oxidable acid such as nitric acid,mixed acid as well as oxidable salt such as  Fe+++,Cu++and sea water |
| Titanium | Applicable in seawater,and kinds of chloride,hypochlorite salt,oxidable acid(including fuming nitric acid),organic acid,alkali etc.Not resistant to a pure reducing acid(such as sulphuric acid,hydrochloric acid)corrosion.But if acid contains antioxidant(such as Fe+++,Cu++)is greatly reduce corrosion. |
| Da | In addition to hydrofluoric acid, fuming sulfuric acid, alkali remaining outside chemicals, including boiling hydrochloric acid |
| Platinum-iridium | Almost be applicable in all chemical mediums except for aqua fortis,ammonium salt. |
