GENERAL PROPERTIES
click to resize photo Semitron® ESd 520HR is a static dissipative reinforced PolyAmide-Imide (Torlon ®). This material has the same general properties as Torlon ® 5530, but with static dissipative properties throughout -- resistivity in the range of 1010 to 1012. It is thermally stable to temperatures of 520°F (270°C) without degradation. Semitron ® ESd 520HR offers high structural strength and stiffness combined with excellent dimensional stability. This material is available in sheets and rods and is  GREEN-BLACK  in color.

Semitron® ESd 520HR is ideal for making nests, sockets and contactors for test equipment and other electronic device handling components. While typical carbon-fiber-enhanced products become irreversibly more conductive when exposed to moderate voltage, only Semitron® ESd 520HR maintains its dielectric performance at high voltages (>100V), while maintaining its mechanical properties.

SEMITRON® ESd DESCRIPTION
Semitron® ESd is a family of static dissipative products designed for use where electrical discharge in operation is a problem. They are commonly used for sensitive electronic components including integrated circuits, hard disk drives, and circuit boards. Semitron® products are also an excellent choice for material handling applications, and components in high speed electronic printing and reproducing equipment.

Semitron® ESd products are inherently dissipative. They do not rely on atmospheric phenomena (humidity) to activate, nor are surface treatments used to achieve dissipation. Static electicity is dissipated through these products as readily as it is dissipated along the surface.
