The SEMITRON ESd family of static dissipative plastics is
designed for applications where electrical discharge in
operation is a problem. They provide a controlled bleed-off of
static charges.
Main characteristics:
permanently static dissipative
dissipate static charges (5 kV) in less than 2 seconds
no metals or graphite / car-bon powder used
There are three SEMITRON® ESd-grades, servicing static
dissipative needs over a broad range of temperatures and
mechanical loading conditions:
SEMITRON®ESd 225 (POM)
(beige)
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 inclu-ding hard disk drives and
circuit boards.
SEMITRON® ESd 410C (PEI)
(black)
Having an excellent mechanical performance up to 210°C,
SEMITRON® ESd 410 provides ESd-solutions at higher temperatures.
Additionally, SEMITRON® ESd 410 exhibits excellent dimen-sional
stability (low coefficient of linear thermal expansion and small
water absorption), ideal for handling equipment in the
electrical/electronic or semiconductor industries.
SEMITRON® ESd 500HR (PTFE + mica)
(white)
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, temperature resistance and low coefficient
of friction.
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. The key features of 520HR are its unique
ability to resist dielectric breakdown at high voltages (>100V).
The graph below demonstrates the electrical performance of
plastic materials commonly used in automated test handlers.
Typical carbon fiber enhanced products become irreversibly more
conductive when exposed to even moderate voltage.
Only SEMITRON® ESd 520HR maintains its performance throughout
the voltage range, while offering the mechanical performance
needed to excel in demanding applications.
SEMITRON® is a registered trade mark of Quadrant Engineering
Plastics Products.
