Cleanroom Safe ESD Polyester Wipers, available in three standard weights: 160 grams per square meter (gsm), 180 gsm, and 200 gsm. Engineered for critical environments, these wipers provide superior cleaning performance while protecting sensitive components from electrostatic discharge (ESD) and particulate contamination.
Technical Parameter Requirements:
Our ESD Polyester Wipers are manufactured to precise specifications to ensure consistency and reliability.
• Material: 100% continuous filament polyester. The material is inherently low-linting and highly durable.
• Surface Resistivity: Typically in the ESD-safe range of 10^6 to 10^9 Ω/sq (per ANSI/ESD S20.20), effectively dissipating
static charges to prevent damage to sensitive components.
• Weight/Variants: Available in three densities to suit different cleaning needs:
◦ 160 g/sqm: A lighter, more pliable wiper for light-duty cleaning and delicate surfaces.
◦ 180 g/sqm: A versatile, medium-weight wiper offering an excellent balance of absorbency, durability, and softness.
◦ 200 g/sqm: A heavier, highly durable wiper for aggressive cleaning, scrubbing, and absorbing larger volumes of solvents and chemicals.
• Cleanroom Classification: Validated for use in ISO Class 3 (Class 1) and better cleanrooms. The wipers are packaged in class-compliant, particle-free packaging.
• Extractables & Linting: Extremely low levels of extractable ions and non-volatile residues (NVR). The continuous filament structure ensures minimal fiber release (low linting).
• Compatibility: Excellent chemical compatibility with a wide range of solvents, acids, and alkalis used in manufacturing processes.
• Packaging: Individually packaged or in clean, static-dissipative poly bags to maintain purity from the factory to your cleanroom.
Product Features & Benefits
Our ESD-safe wipers are designed with performance and protection in mind.
• Superior ESD Protection: Safely dissipates static electricity, safeguarding sensitive microelectronics, PCBs, and assemblies from ESD damage during production and cleaning.
• Ultra-Low Linting: Made from continuous filament polyester, these wipers shed virtually no fibers, preventing contamination in critical cleanroom and optical applications.
• High Absorbency & Wiping Efficiency: The porous structure and specific weave patterns ensure efficient absorption and removal of contaminants, oils, and process chemicals.
• Exceptional Durability & Abrasion Resistance: Highly resistant to tearing and fraying, even when used with aggressive solvents, ensuring the wiper does not become a source of contamination.
• Chemically Inert & Low NVR: Leaves minimal residue, ensuring no interference with delicate processes such as coating, bonding, or printing.
• Soft and Non-Abrasive: Safe for use on delicate surfaces without scratching, including polished wafers, optical lenses, and precision mechanical parts.
