Static Dissipative Acetal Copolymer ESd

Static dissipative acetal is a non-carbon-filled, permanently static dissipative material. It is non-migratory and non-humidity dependent. With enhanced lubricity, static dissipative acetal provides superior wear resistance and ease of machining. Its extremely low outgassing values and non-sloughing characteristics make it ideal for applications where particulate generation cannot be tolerated. Enhanced lubricity, chemically resistant, and dimensionally stable. 

They do not rely on atmospheric phenomena to activate, nor are surface treatments used to achieve dissipation. Static electricity is dissipated through these products as readily as it is dissipated along the surface. All of these products dissipate 5 KV in less than 2 seconds per Mil-B-81705C. Acetal SD (ESd) is ideal for fixturing used in the manufacturing of hard disk drives or for handling in-process silicon wafers.

Static dissipative acetal contains no carbon fibers or powders and is generally accepted for clean room use in medical applications. It has a surface resistivity of 109 to 1011 ohm/square and excellent bearing and wear characteristics.
