ThermaSeal™ Sealed Edge Dry Wipers Heat-Sealed Edge Wipers for Consistent Low-Lint Performance and Controlled Cleaning ThermaSeal™ sealed edge dry wipers utilize thermal edge sealing technology to stabilize fibers and reduce particle generation. Designed for controlled environments, these wipers provide reliable low-lint performance, durability, and cost-effective contamination control. ▼ EXPAND TECHNICAL REFERENCE
Thermal Edge Sealing for Controlled Fiber Stability
ThermaSeal™ wipers are manufactured using a heat-based edge sealing process that bonds and stabilizes fibers along the perimeter of the wipe. This process reduces loose fibers and minimizes particle generation compared to traditional cut-edge wipers.
While not as aggressive as laser sealing, thermal sealing provides a strong balance between contamination control and cost efficiency. The result is a reliable, low-lint wiper suitable for a wide range of cleanroom and controlled environment applications.
These wipes are typically constructed from polyester or synthetic knit materials and are designed to deliver consistent performance in ISO Class 5–8 environments and general cleanroom operations.
ThermaSeal™ Edge Technology
Thermal Sealing Process:
Heat is applied to fuse fibers at the edge, preventing fraying and loose particle release.
Stabilized Fiber Structure:
Enhances edge durability during wiping and handling.
Cost-Performance Balance:
Provides improved lint control without the higher cost of laser-sealed options.
Compatible Substrates:
Typically used with polyester knit or synthetic cleanroom materials.
Fast Selection Guidance
  • ISO Class 5–8 environments: ideal balance of performance and cost.
  • General cleanroom cleaning: reliable low-lint performance.
  • Cost-sensitive applications: more economical than laser-sealed wipes.
  • Moderate contamination control: suitable for non-critical processes.
  • Durability needs: thermal sealing improves edge strength.
  • Process standardization: consistent performance across batches.
ThermaSeal™ Wiper Performance Considerations
  • Lint Reduction: improved over cut-edge wipes due to sealed perimeter.
  • Edge Durability: resists fraying during wiping and handling.
  • Cost Efficiency: lower cost compared to laser or ultrasonic sealing.
  • Particle Control: suitable for moderate to controlled environments.
  • Absorbency: dependent on base material (polyester or blend).
  • Surface Compatibility: safe for most cleanroom surfaces.
  • Operational Reliability: consistent performance in routine cleaning tasks.
Typical Applications
  • General cleanroom maintenance (ISO Class 5–8)
  • Electronics manufacturing and assembly
  • Pharmaceutical support areas
  • Equipment and tool cleaning
  • Laboratory and research environments
  • Surface preparation and wipe-down tasks
  • Controlled environment cleaning programs
  • Production and support areas
Common ThermaSeal™ Wiper Issues to Avoid
  • Using thermal-sealed wipes in ultra-critical ISO Class 3–4 environments.
  • Assuming all sealed edges provide the same performance level.
  • Using in applications requiring ultra-low NVR or extractables without validation.
  • Overlooking compatibility with aggressive solvents or chemicals.
  • Choosing based solely on cost rather than contamination requirements.
  • Not aligning wipe selection with process cleanliness standards.
