Challenges & Solutions for Using PTFE Washers
1. Low Mechanical Strength
- Challenge: PTFE is softer than metal washers and may deform under high loads.
- Solution: Reinforced PTFE washers with glass or carbon fillers improve mechanical strength.
2. Susceptibility to Creep & Cold Flow
- Challenge: PTFE can deform over time under constant pressure.
- Solution: Use metal-backed PTFE washers or reinforced grades for high-load applications.
3. High Initial Cost
- Challenge: PTFE washers are more expensive than rubber or fiber washers.
- Solution: Their long lifespan and minimal maintenance make them a cost-effective investment.
4. Limited Surface Compatibility
- Challenge: PTFE requires smooth flange surfaces for optimal sealing.
- Solution: Proper surface preparation or thicker PTFE washers can improve sealing efficiency.
