Characteristics: The charge dissipates extremely fast, which may cause rapid discharge of electrostatic sensitive components (CDM damage). It is often used in situations where grounding is required and charges need to be discharged quickly, such as anti-static floors and table MATS.
2)Static Dissipation Material (Static Dissipative) : Surface Resistivity: 1 x 10⁴ Ω ka se 1 x 101 Ω Volume Resistivity: 1 x 101 Ω·cm ka se 1 x 101 Ω·cm ma: Nin ye anti{9}}static silicone foam board ye!
