Semitron® Esd 225 (Static Dissipative Plastic)
The Semitron ESd family of static dissipative products was 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 and electrically stable unlike many other “dissipative” plastic shapes. 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 Semitron ESd products dissipate 5 KV in less than 2 seconds per Mil-B-81705C
Main properties of our range of Semitron ESD sheet, rod and tube are:
- Permanently static dissipative
- Dissipate static charges (5 kV) in less than 2 seconds per mil-B-81705 C
- No metals or graphite / carbon powder used

 Semitron ESd 225 | Semitron ESd 225 is an acetal based static dissipative material ideal for material handling applications. It avoids discharge problems for parts intended for human contact. Semitron ESd 225 is also an excellent choice for fixturing used for handling in-process silicon wafers or used in the manufacturing of sensitive electronic components including hard disk drives and circuit boards.
Surface resistivity: 1010 - 1012 ohms/sq
Available colours: Beige Available to buy in: sheet and rod |

| | Semitron ESd 410C | Having an excellent mechanical performance up to 210°C, Semitron ESd 410 provides static dissipative solutions at higher temperatures. Additionally, Semitron ESd 410C exhibits excellent dimensional stability (low coefficient of linear thermal expansion and small water absorption), ideal for handling equipment in the electrical/electronic or semiconductor industries.
Surface resistivity: 104 - 106 ohms/sq
Available colours: Black Available to buy in: sheet and rod |

| | Semitron ESd 500HR | Reinforced with a proprietary synthetic mica, Semitron ESd 500 offers an excellent combination of low frictional properties, good dimensional stability and electrostatic dissipation. Whenever virgin PTFE causes electrical discharge problems, Semitron ESd 500 will provide a controlled bleed-off of static charges while maintaining typical PTFE properties such as broad chemical resistance and low coefficient of friction.
Surface resistivity: 1010 - 1012 ohms/sq.
Available colours: White Available to buy in: sheet |

| | Semitron ESd 520HR | Semitron ESd 520HR has an industry first combination of electrostatic dissipation (ESd), high strength and heat resistance. This new ESd material is ideal for making nests, sockets and contactors for test equipment and other device handling components in the semiconductor industry. The key feature of Semitron ESd 520HR is its unique ability to resist dielectric breakdown at high voltages (>100V). Whereas e.g. typical carbon fiber enhanced products become irreversibly more conductive when exposed to even moderate voltages, Semitron ESd 520HR maintains its electrical performance throughout the voltage range 100 to 1000 V, while offering the mechanical performance needed to excel in demanding applications.
Surface resistivity: 1010 - 1012 ohms/sq.
Available colours: Khaki-grey Available to buy in: sheet |
