Semitron® Teflon ESd 500HR (PTFE+Mica)
Brand: 
- Permanently antistatic
- Static charge dissipation (5 kV) in less than 2 seconds
- Metal- and graphite/coal dust-free
Interested in this product?
Reinforced with synthetic patented MICA, this material offers an excellent combination of properties, including low friction, good dimensional stability, and electrostatic dissipation.
Where virgin PTFE causes electric discharge issues, this formulation is designed for controlled electrostatic charge release, although it has some typical features of PTFE.
