Electrostatic dissipative (ESD) plastics
By adding conductive microfibres, hydrophilic polymers or other inherently conductive materials, permanent static dissipative properties (ESD) can be generated which represent a significantly lower risk of contamination. These additives are also much more resistant to abrasion and are therefore preferred for applications in the electrical industry or semiconductor production. POLYTRON has a series of high-performance plastics which are modified accordingly and are therefore particularly suitable for use in the examination or testing of semiconductors and other electronic components.
- Semitron® ESD 410 – polyetherimide (PEI) electrostatically conductive
- Semitron® ESD 480 – polyetheretherketone (PEEK) electrostatically conductive
- Semitron® ESD 500 – polytetrafluorethylene (PTFE) electrostatically dissipative
- Semitron® ESD 520 – polyamide imide (PAI) electrostatically conductive
The materials Semitron® ESD 500 and 520 are also characterised by a particularly stable dielectric strength even at high voltages. While plastics that are dissipative mainly due to carbon quickly achieve higher conductivity when higher voltages (up to 1000 V) are applied, the surface resistance of the so-called "high resistivity" materials Semitron® ESD 500 and 520 remains more or less constant.
