Cleanroom products are specialized materials designed to maintain contamination control in controlled environments. Static control and ESD (Electrostatic Discharge) protection products prevent damage from static electricity, while cleanroom treatments, cleaners, and wipes ensure particulate and microbial contamination removal. These products are critical in semiconductor manufacturing, pharmaceuticals, aerospace, and biotechnology industries where nanoscale precision and sterility are required.
| Type | Functionality | Applications |
|---|---|---|
| ESD Mats | Dissipate static charges from personnel/equipment | Electronics assembly lines |
| Ionizers | Neutralize static charges in non-conductive materials | Photolithography processes |
| Conductive Wipes | Remove particles while preventing static buildup | Optical component cleaning |
| pH-Neutral Cleaners | Remove organic/inorganic contaminants without surface damage | Medical device manufacturing |
Cleanroom wipes typically use nonwoven synthetic fibers (e.g., polyester, nylon) with edge-binding technology to prevent fiber shedding. Cleaners contain deionized water, surfactants, and chelating agents. ESD products incorporate conductive polymers or carbon additives. Surface treatments often use perfluoropolyether (PFPE) coatings for low particle adhesion.

Consider chemical compatibility with target surfaces, required cleanliness class (ISO 14644-1), ESD protection level (IEC 61340-5-1), and regulatory certifications (FDA, REACH). For critical processes, perform particle extraction testing using scanning electron microscopy.
Key developments include: - Nanoparticle-enhanced cleaning formulations - Self-diagnostics ESD materials with embedded sensors - Biodegradable wipes using polylactic acid (PLA) - AI-powered contamination monitoring systems integration
Case Study: In a 5nm semiconductor fab, implementation of PFPE-coated wipes reduced particle defects by 47% while maintaining surface resistivity below 10^8 /sq.
