Antistatic Ceramics
Antistatic ceramics integrate conductive phases into the ceramic body to achieve controlled surface resistance and stable electrostatic dissipation. Unlike surface coatings, the antistatic function remains effective even after machining, cleaning, or long-term use. This makes them ideal for semiconductor equipment, medical devices, and cleanroom automation.
⚡ Antistatic Ceramics
Anti-Static Coating
Anti-static coatings, such as ESD-DLC (Electrostatic Dissipative Diamond-Like Carbon) films, provide uniform surface resistance, excellent wear resistance, and high-temperature durability. These coatings are applied to precision fixtures, nozzles, wafer handling tools, and other electronic components to prevent static charge buildup and extend service life.
