SEMITRON ESd 225 (beige) (POM)
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.
Delivery Programme: rod 4.76 - 101.60 mm, plate 8 - 50 mm
SEMITRON ESd 410C (black) (PEI)
Having an excellent mechanical performance up to 210°C, SEMITRON ESd 410C provides ESd- 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.
Delivery Programme: rod 12.70 - 247.65 mm, plate 9.53 - 50.80 mm, tube 50.80 - 374.65 mm
SEMITRON ESd 500HR (white) (PTFE + mica)
Reinforced with a proprietary synthetic mica, SEMITRON ESd 500HR offers an excellent combination of low frictional properties, good dimensional stability and electrostatic dissipation. Whenever virgin PTFE causes electrical discharge problems, SEMITRON ESd 500HR will provide a controlled bleed-off of static charges while maintaining typical PTFE-properties such as broad chemical resistance, temperature resistance and low coefficient of friction.
Delivery Programme: plate 6.35 - 50.80 mm
SEMITRON ESd 520HR (khaki grey) (PAI)
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.
Delivery Programme: plate 9.53 - 38.10 mm
