What Is the Best O-Ring Material for Cleanroom Tools? If you’re specifying seals for cleanroom equipment, material choice matters more than almost any other design decision. The wrong elastomer can become a source of contamination — outgassing volatile compounds, shedding particles, or reacting with process chemicals in ways that compromise the entire environment. The right […]
Why Semiconductor Applications Require a Different Approach to Material Selection O-rings create the seal for vacuum environments, prevent toxic gas leaks, and contain corrosive chemicals. They are necessary for protecting highly sensitive wafers from particulate contamination and process defects. Material selection is also a key factor in reducing stickiness and adhesion issues for wafer transfer. Therefore, selecting the right sealing […]
