| Material name | Feature | Application | Application classification | |
| Advantage | Disadvantage | |||
Polycarbonate (PC) | 1. High impact strength and good creep resistance 2. Good heat resistance, low embrittlement temperature (-130 °C) can resist the effects of sunlight, rain and temperature changes 3. Good chemical properties and high transparency 4. Good dielectric properties 5. Good dimensional stability | 1. Poor solvent resistance 2. Stress cracking 3. Long-term immersion in boiling water is easy to hydrolyze 4. Poor fatigue strength | General structural parts | Wide range of instrumentation enclosures, parts for aircraft, automotive, electronics, textile coiled tubes, vaporizers, timer components, helmets, impact resistant aerospace glass, etc. Also commonly used in daily necessities |
| Polyphenylene ether (PPO) | 1. Excellent overall performance, excellent water vapor resistance and dimensional stability and excellent electrical insulation properties 2. Hardness is higher than nylon, polycarbonate, polyoxymethylene, and creep is small 3. Hardly affects acid and alkali | 1. Molding fluidity is poor 2. High price | For wet, loaded, and electrically insulated applications | Electronic instruments, automobiles, mechanical equipment parts |
