Material Description

Semitron® ESd is a family of static dissipative products.  Semitron Grades are designed for use where electrical discharge in operation is a problem.  Semitron® ESd grades are commonly used for sensitive electronic components including integrated circuits, hard disk drives, and circuit boards.  Semitron® products are used for material handling applications and components in high speed electronic printing and reproducing equipment.  Semitron® ESd grades are inherently dissipative.  They do not rely on humidity to activate.  Static electricity is dissipated through these products as readily as it is dissipated along the surface.

Grades of Semitron

Semitron® ESd 225

Semitron® ESd 225 is a static dissipative acetal.  This material has the same general properties as unfilled acetal, but with static dissipative properties.  Its resistive range is 1010to 1012.  Semitron® ESd 225 can be used up to temperatures of 225°F without degradation, and it has broad chemical resistance and good wear resistance.

Semitron® ESd 410C

Semitron® ESd 410C is a static dissipative Polyetherimide (Ultem®).  This material has the same general properties as unfilled Ultem, but with static dissipative properties.  Its resistive range is 104 to 106.  Semitron® ESd 410C can be used up to temperatures of 410°F without degradation, and it has low stress for tighter tolerances during machining.

Semitron® ESd 420

Semitron® ESd 420 is a static dissipative Polyetherimide.  This material has the same general properties as PEI, but with static dissipative properties.  Its resistive range is 106 to 109.  Semitron® ESd 420 is thermally stable to temperatures of 420°F without degradation.

Semitron® ESd 500HR

Semitron® ESd 500HR is a static dissipative reinforced PTFE (PolyTetraFluoroEthylene).  This material has the same general properties as unfilled PTFE, but with static dissipative properties. Its resistive range is 1010 to 1012.  Semitron® ESd 500HR is thermally stable to temperatures of 500°F without degradation, and it has a high thermal insulation and a low coefficient of friction.

Semitron® ESd 520HR

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.  Its resistive range of 1010 to 1012.  Semitron® ESd 520HR is thermally stable to temperatures of 520°F without degradation, and it has high structural strength and stiffness combined with excellent dimensional stability.  Semitron® ESd 520HR is ideal for making nests, sockets, and contactors for test equipment and other electronic device handling components.  It maintains its dielectric performance at high voltages (>100V), while maintaining its mechanical properties.  Most other carbon-fiber-enhanced products become irreversibly more conductive when exposed to moderate voltage.
