SEMITRON® ESD 410C (static dissipative PolyEtherImide / Ultem ®)

Material Information

Semitron® ESD 410C PEI is a static dissipative PolyEtherImide (Ultem®) that has the same general properties of unfilled Ultem® but with additional static dissipative properties. It has a surface resistivity of 10^4 – 10^6 Because of its dissipative properties, Semitron® ESD is ideal for use in applications that give off electrical discharge. Semitron® ESD’s dissipative properties do not rely on humidity to activate, nor are surface treatments necessary. The Semitron® ESD 410C PEI grade in particular may be used in temperatures up to 410º F without degradation and offers low stress for tighter tolerances during machining, a low coefficient of linear thermal expansion, and low water absorption. It is available in a black color in the forms of sheet and rod.
