Alphasorb® HC Polyester Cleanroom Wipers High-Capacity Sorbent Polyester Wipes for Critical Cleaning Alphasorb HC polyester cleanroom wipes combine continuous filament polyester with enhanced absorbency technology, delivering high liquid capacity, low particle generation, and controlled extractables for semiconductor fabs, pharmaceutical cleanrooms, biotechnology manufacturing, optics production, and electronics assembly environments. ▼ EXPAND TECHNICAL REFERENCE
High-Capacity Absorbent Wipes for Solvent Cleaning
Alphasorb HC polyester cleanroom wipes are engineered for applications that require both the low-lint performance of continuous filament polyester and significantly improved liquid handling capability. The HC (High Capacity) design increases the wipe’s ability to absorb and retain solvents while maintaining contamination-control performance required for critical manufacturing environments.
These wipes are particularly useful in solvent wipe-down procedures where the ability to manage liquid volume is important. The enhanced sorbent structure allows operators to distribute cleaning solutions more evenly across surfaces without excessive dripping or solvent pooling.
Alphasorb HC wipes are commonly used in semiconductor wafer fabrication, pharmaceutical production cleanrooms, biotechnology laboratories, optics manufacturing facilities, and electronics assembly environments where controlled solvent application and contamination control are required.
High-Capacity Polyester Fabric Technology
Continuous Filament Polyester:
The wipe is constructed using long polyester filaments that minimize fiber shedding and particle generation compared with staple fiber materials.
