The difference between pei and PTFE

1. The most important thing is the intensity. This is judged from the appearance.

2, temperature resistance, pei temperature resistance can reach 260 ℃, but PTFE machiningcan only reach 220 ℃, and when the temperature exceeds 150 ℃, PTFE softens, without any strength, but pei still maintains good mechanical strength

3. In the molding process, PTFE can only be made into rods or plates by…
