What is the difference between peek material and PTFE?
1. The difference in characteristics, PEEK is a thermoplastic material that can be processed by injection molding. PTFE is a thermosetting plastic that can only be formed by cold pressing and sintering, both of which can be processed from bar stock or sheet metal.
2. The temperature resistance is different. The temperature resistance of PEEK can reach 260°C, while the temperature of PTFE can only reach 220°C. After the temperature exceeds 150°C, PTFE softens and has no strength, but PEEK still maintains good mechanical strength.
3. The difference in corrosion resistance. The corrosion resistance of PTFE is better than that of PEEK, and the prices of the two are quite different.
5. The price difference, PEEK is much more expensive than PTFE.
4. Different uses, PEEK is widely used in aerospace, medical machinery, automobile industry, petroleum industry, etc. PTFE can be used as a lubricating material, and can also be used as an electrical insulator, capacitor dielectric, wire insulation, electrical instrument insulation, etc.
