PEEK, PFA, PTFE, HDPE which is the most wearable?
Q: PEEK, PFA, PTFE, HDPE which is the most wearable?
A: certainly PEEK is the most wearable. PTFE and PEEK are self-lubricating and have abrasion resistance. But the PTFE is soft, creep resistance is poor. PEEK has good wear resistance, mechanical properties and solvent resistance is also very good, only concentrated sulfuric acid can dissolve. HDPE is the weakest.
