Thermaseal® 60 Polyester Cleanroom Wipers Laser-Sealed Polyester Wipes for ISO 3–5 Critical Cleaning Thermaseal 60 polyester cleanroom wipes are constructed from continuous filament polyester knit fabric with laser-sealed edges to deliver extremely low particle generation, low extractables, and reliable durability for semiconductor fabs, pharmaceutical cleanrooms, biotechnology production, optics manufacturing, and precision electronics assembly. ▼ EXPAND TECHNICAL REFERENCE
Laser-Sealed Polyester Wipes for Critical Contamination Control
Thermaseal 60 cleanroom wipes are engineered for contamination-sensitive manufacturing environments where particle generation and fiber release must be tightly controlled. The wipes are manufactured using continuous filament polyester yarns, which significantly reduce lint compared with staple-fiber wiping materials.
A precision laser sealing process thermally bonds the wipe edges, preventing loose fibers from releasing during wiping procedures. This sealed-edge construction improves wipe integrity and helps maintain extremely low particle levels during aggressive wipe-down operations.
Thermaseal 60 wipes are commonly used in ISO Class 3–5 cleanrooms including semiconductor wafer fabrication, pharmaceutical sterile manufacturing, biotechnology laboratories, medical device production, and advanced optics cleaning environments.
Continuous Filament Polyester Construction
Continuous Filament Polyester Fibers:
Long polyester filaments reduce lint and particle generation compared with traditional staple fiber wipes used in industrial environments.

Knit Polyester Fabric:
The knit structure provides durability and flexibility, allowing the wipe to conform to surfaces while maintaining strength during cleaning operations.
