Semitron® ESd 420 PEI


Semitron® ESd 420 PEI electrostatic dissipative shapes exhibit high strength and stiffness, and excellent resistivity in the 10E5 to 10E8 ohms per square range. Semitron® ESd 420 PEI does not rely on atmospheric phenomena (humidity) to activate, nor are surface treatments used to achieve dissipation. This grade in particular excels in high temperature environments, making it ideal for extreme structural applications in semiconductor and electronics markets.
