POM-C SD (Static-Dissipative Copolymer Acetal) — Sheet & Rod

POM-C SD is a static-dissipative acetal copolymer engineered to safely dissipate electrostatic charges while maintaining the mechanical strength, dimensional stability, and machinability of standard POM-C (Acetal Copolymer). Unlike unfilled copolymer acetal, which is electrically insulative, POM-C SD incorporates a controlled conductive additive that enables predictable static dissipation — an essential requirement in ESD-sensitive manufacturing environments. Ready Plastics stocks POM-C SD sheet for semiconductor processing, electronics manufacturing, and cleanroom applications.

In environments where electrostatic discharge (ESD) poses a risk to sensitive components or processes, material selection is critical. POM-C SD provides a surface resistivity in the static-dissipative range, allowing accumulated static charges to bleed off at a controlled rate — fast enough to prevent harmful discharge events, slow enough to avoid being classified as conductive. This makes it suitable for wafer-handling equipment, PCB fixtures, electronic assembly tooling, and cleanroom material-handling components where both static control and precise mechanical performance are required.

Mechanical and dimensional performance. POM-C SD retains the core benefits of the POM-C base resin: low moisture absorption, dimensional stability, and excellent machinability. It machines cleanly on conventional CNC and manual equipment, allowing precise fabrication of complex components to tight tolerances.

Sister grades. For wear-focused applications without ESD requirements, POM-C Moly and POM-C PTFE provide internal lubrication for reduced friction and extended wear life. For impact resistance, see POM-C MT. For the highest mechanical strength in the acetal family, see POM-H (Acetal Homopolymer).
