The following are common thermoplastic materials with acid and alkali resistance, including their properties, operating temperature ranges, and typical application areas.
| Material Name | Abbreviation | Acid/Alkali Resistance | Operating Temperature Range(°C) | Characteristics | Common Applications |
| Polypropylene | PP | Excellent | 0 ~ 100 | Excellent resistance to most acids and alkalis, lightweight, low cost | Chemical drums, pipe fittings, filter cartridge housings |
| Polyethylene | PE | Excellent | -50 ~ 90 | Highly stable against acids, alkalis, and salts; easy to form | Piping, tanks, containers |
| High-Density Polyethylene | HDPE | Excellent | -50 ~ 110 | Good mechanical strength, resistant to various corrosive chemicals | Chemical drums, tanks, bases |
| Polyvinylidene Fluoride | PVDF | Excellent | -40 ~ 150 | Resistant to strong acids and alkalis, high heat resistance and mechanical strength | Chemical pumps, semiconductor cleaning systems |
| Polyethylene Tetrafluoroethylene | PTFE | Excellent | -200 ~ 260 | Virtually inert, resistant to all acids and alkalis, extremely low friction coefficient | Sealing gaskets, linings, valve seats |
| Ethylene–Tetrafluoroethylene Copolymer | ETFE | Excellent | -80 ~ 150 | Slightly lower chemical resistance than PTFE, but more rigid | Chemical tubing, film, fittings |
| Fluorinated Ethylene Propylene | FEP | Excellent | -200 ~ 200 | Superior chemical resistance, high transparency | Linings, wire coatings |
| Perfluoroalkoxy Resin | PFA | Excellent | -200 ~ 260 | Nearly absolute chemical inertness, exceptional temperature resistance and cleanliness | Semiconductor equipment, chemical fluid transfer |
| Polyphenylene Sulfide | PPS | Good | -40 ~ 220 | High chemical resistance, suitable for high-temperature conditions | Automotive components, electrical parts |
| Polyetheretherketone | PEEK | Good | -50 ~ 250 | Excellent high-temperature tolerance, resists most inorganic acids and alkalis | Medical devices, pump housings, valve components |
| Polyetherimide | PEI (Ultem) | Moderate | -50 ~ 170°C | Resistant to weak acids/alkalis and most solvents; not resistant to strong acids | Electronics, medical components |
