The volume resistivity of the unfilled PEEK material is 1016 ，It is an insulating plastic material.This characteristic causes the material surface to accumulate charges easily when used in fields such as electronics, semiconductors, medicine, aerospace, etc. that are sensitive to static electricity. Due to the high insulation property of PEEK material, the accumulated charges cannot be promptly dissipated.
In the semiconductor field, electrostatic discharge can cause breakdown of electronic components.
In an environment prone to fire and explosion, the generation of static electricity may cause a fire or an explosion.
PEEK material possesses outstanding comprehensive properties, including excellent high-temperature resistance, excellent mechanical strength, corrosion resistance, and radiation resistance.
The outstanding high-temperature resistance of PEEK enables it to be used for a long time at a temperature of 260°C, and even for a short period at 300°C. The mechanical properties of PEEK will not show significant degradation under such high temperatures for a long time. Even when approaching the melting point, it can still maintain good mechanical properties.

The resistance value of the anti-static PEEK material is between 106 and 109.In PRES,we can custom the resistance value as you need.
PRES offers three forms of anti-static PEEK materials: one is anti-static PEEK particles, and the other is anti-static PEEK sheets and rods.
ESD PEEK pellets With different fluidity and melt strength is suitable for injection and extrusion.
We have full size ESD PEEK sheet and rods in stock and we can cut into the size as you need.
