PEP wire is made of Polyether ether ketone (PEEK), and PTEP wire is made of blending of polytetrafluoroethylene (PTFE) and Polyether ether ketone (PEEK). This blend combines the advantages of PTFE and PEEK, such as high temperature resistance, chemical corrosion resistance, high insulation, and low friction coefficient.

2. Heat resistance:

The continuous use temperature range of PEP wire is generally  50 ℃ to+200 ℃,

The high temperature resistance of PTEP wire depends on the blending ratio of polytetrafluoroethylene (PTFE) and Polyether ether ketone (PEEK), but its maximum operating temperature is usually about 250 ℃.

3. Chemical corrosion resistance:

Both PEP and PTFE wires have excellent chemical corrosion resistance and can resist the erosion of various chemical media such as acids, alkalis, and salts.

4. Mechanical strength:

The mechanical strength of PTFE is slightly better than that of PEP,

Overall, both PEP wire and PTEP wire are wires made of high performance engineering plastics, which have characteristics such as high temperature resistance, chemical corrosion resistance, high insulation, and low friction coefficient. They have interchangeability in certain application scenarios, but their specific selection needs to be based on actual needs and environmental conditions.
