High-performance plastics are advanced materials which are designed to meet the demands of extreme environments and critical applications.These materials could provide high-temperature/chemical resistance,high mechanical and low water absorption properties.
Here is the comparasion table for different high performance thermalplastic material:
| Material | Operating Temperature Range (°C) | Chemical Resistance | Water Absorption (%) | Wear Resistance | Electrical Insulation | Flame Retardancy | Typical Applications |
| PPS | -40 to 230 | Excellent, resistant to most acids, bases, organic solvents, and fuels | < 0.02 | Good, but less effective under high loads compared to PEEK | Excellent, good dielectric properties | Good, meets UL 94-V0 standard | Automotive components, electrical parts, industrial pumps, and valves |
| PPA | -40 to 230 | Good, slightly inferior to PPS and PEEK in high-concentration acids/bases | 0.2-0.5 | Good, suitable for moderate friction conditions | Good electrical insulation | Moderate, can be flame-retardant with additives | Automotive (cooling system, fuel system), electrical connectors |
| PEEK | -50 to 260 | Excellent, resistant to nearly all chemicals, including high-temperature acids and bases | < 0.1 | Excellent, ideal for high-load, high-friction applications | Excellent, used for electrical insulators | Excellent, meets UL 94-V0 standard | Aerospace, medical devices, high-performance automotive parts, gears, bearings |
| PTFE | -200 to 260 | Exceptional, resistant to virtually all chemicals, including aggressive acids and bases | < 0.01 | Excellent, very low friction | Excellent, used as electrical insulation | Excellent, self-extinguishing | Chemical processing, seals, gaskets, electrical insulation, food processing |

| Tensile Modulus | MPa | ISO 527 | 15,000 |
| Flexural Strength | MPa | ISO 178 | 280 |
| Flexural Modulus | GPa | ISO 178 | 14 |
| Charpy Impact Strength (Unnotched) | kJ/m² | ISO 179 | 60 |
| Charpy Impact Strength (Notched) | kJ/m² | ISO 179 | 11 |
| Melting Point | °C | ISO 11357 | 280 |
| Heat Deflection Temperature (1.8 MPa) | °C | ISO 75 | 265 |
| Flame Rating | – | UL-94 | V-0 |
The design of parts bonding rubber and high-performance plastic products can achieve sealing and high strength of the parts.
Rubber material need to be selected according to the working enviroment, such as fuel,ATF oil, gas.
