    • PEEK: Approximately 500-1000 yuan/kg (general grade)

      • Cost difference: The raw material cost of PEEK is about 5-8 times that of PTFE.

      Processing Cost

      PTFE:

    • Processing method: Compression molding + sintering, long cycle (several hours to tens of hours)
    • Difficult to process, hard to recycle
    • Processing cost: Medium

      • PEEK:

    • Processing method: Injection molding, extrusion, short cycle (several minutes to tens of minutes)
    • Recyclable, high processing efficiency
    • Processing cost: Low (in mass production)

      • Life Cycle Cost

      Although PEEK has high raw material costs, it offers:

    • Longer service life (wear-resistant, fatigue-resistant)
    • Greater design freedom (complex shapes can be injection molded)
    • Lower maintenance costs
    • Better performance reliability

      • In specific applications, PEEK’s total life cycle cost may actually be lower.

      5. Selection Recommendations

      When to Choose PTFE

      ✅ Prioritize PTFE when:
      1. Extremely low coefficient of friction and self-lubricating properties are needed

      3. Working temperature ranges from -200°C to +260°C
      4. Excellent electrical insulation properties are required
      5. Budget is limited and mechanical property requirements are not high
      6. Application environment is static or low-stress

      When to Choose PEEK

      ✅ Prioritize PEEK when:
      1. High mechanical properties (high strength, high modulus) are needed
      2. Withstanding high loads, high stresses, or dynamic loads
      3. Excellent wear resistance and fatigue resistance are required
      4. Precise dimensional stability and low creep are needed
