Polyoxymethylene Copolymer (Electrically Conductive)
Brand: GEHR POM-ELS® — GEHR, Ms Viscom MSC — Ms Viscom, Sustarin® C ESD 60 PLUS — Röchling
Standards: ISO 9988, ASTM D4181
POM-C EL (Electrically Conductive) has a surface resistivity of ≤10⁴ Ω — it actively dissipates electrical charge to earth. Required for ATEX explosion protection zones (Zone 1 and 2), earthing strips, flanges and components in contact with flammable powders or gases. The conductivity is generated by a specially adjusted additive that does not migrate to the surface, ensuring stable and consistent conductivity throughout the product lifetime.
Key distinction from POM-C ESD (Antistatic):
• POM-C EL: ≤10⁴ Ω → ATEX, explosion protection, earthing
• POM-C ESD: 10⁶–10⁹ Ω → Electronics, cleanroom, semiconductor
