General Info

Semitron ® ESd 480 is a static dissipative reinforced PolyEtherEtherKetone (PEEK). This material has similar general properties as Semitron ® ESd 520HR, but with the more chemically resistant properties of PEEK base material. Semitron ® ESd 480 has static dissipative properties throughout -- resistivity in the range of 10^5 to 10^8 ohm/square. It is thermally stable to temperatures of 475°F (248°C) without degradation and offers high structural strength and stiffness combined with excellent dimensional stability. In addition, Semitron ® ESd 480 exhibits the excellent chemical resistance properties of standard PEEK, including resistance to weak acids, all alkalies, aliphatic and aromatic hydrocarbons, ketones, esters, chlorinated solvents, alcohols, and inorganic salt solutions (all at 73°F). Semitron ® ESd 480 is not resistant to concentrated acids.

Key Properties

Surface resistivity 10^5 – 10^8 Ohm/Square (Static Dissipative Range)
Thermal performance to 480°F (248°C) Continuous Use
Excellent Chemical Resistance
Excellent Dimensional Stability
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 electricity is dissipated through these products as readily as it is dissipated along the surface.

Limitations

Poor Chemical Resistance to Halogens and Their Acids Including Bromine, Chlorine, Fluorine, HBr and HF

Applications

Burn in Test Sockets, Contactors & Nests
Critical Test Fixture Applications
Electronic Device Handling Equipment
High Temp Fixtures That Require Static Control
Structural Applications in Wet Process Tools
Wafer Handling Components

Manufacturer Trade Names

Semitron® Esd 480

Boedeker Plastics, Inc. stocks & supplies plastic sheet, rod, tube, film and custom profiles and machine parts from these shapes that are produced from plastic resin. In many cases the manufacturer of the shape has their own product trade name. If your specification calls for a specific resin grade or manufacturer trade name, we can supply a shape made from that resin to meet your specification or suggest an equal. If you require a specific resin or brand it must be specified at the time of order.
