Protecting the Air, Shielding the Core
CC MATTING’S Polymeric Matting is ASTM E595 Certified and Changes the game for advanced cleanrooms When engineering an elite-tier cleanroom environment—whether for semiconductor fabrication, cutting-edge biotechnology, or pharmaceutical compounding—the standard playbook focuses aggressively on particulate control. You calculate floor rotations, implement strict gowning policies, and run high-efficiency HEPA and ULPA filtration systems. But there is a silent, airborne threat that traditional filtration cannot catch: molecular outgassing. Many facility managers don't realize that the very materials brought in to protect the cleanroom can inadvertently pollute its atmosphere. Traditional floor mats, flexible plastics, and low-grade adhesives steadily release volatile organic compounds (VOCs) and chemical vapors directly into the cleanroom envelope. To eliminate this hidden risk, CC Matting has established a new benchmark for physical contamination control. Our high-performance polymeric matting has been rigorously evaluated under ASTM E595 protocols, setting a definitive, low-outgassing standard for critical controlled environments.


What is Molecular Outgassing? Outgassing is the physical process where trapped gases, residual manufacturing solvents, plasticizers, or moisture escape from a solid material and enter the surrounding atmosphere. This phenomenon accelerates significantly in environments with controlled airflow, varying temperatures, or low localized pressures. THE CYCLE OF OUTGASSING FAULT [Low-Grade Polymer] --> Releases Volatile Vapors (Outgassing) | v [Air Flow Circulation] --> Carries Vapors Past Filtration Systems | v [Critical Target] --> Residue Condenses on Lenses, Wafers, & Labs While HEPA filters are masterclasses at catching physical particles like dust or skin flakes, they are entirely porous to molecular vapors. Once a material outgasses inside a cleanroom, those volatile molecules circulate freely until they find a cool surface to settle on.

  • In Semiconductor & Optics Fabrication: These micro-vapors condense onto precision lenses, mirrors, and silicon wafers, causing irreversible "fogging," chemical trace degradation, and wafer defects.
  • In Pharmaceutical & Medical Device Environments: Outgassed compounds compromise sterile atmospheres, cross-contaminate micro-testing samples, and introduce unapproved chemical trace profiles into ultra-pure environments.

The Hard Numbers: CC Matting’s Verified Performance Originally developed by NASA to screen materials destined for specialized spacecraft and satellite payloads, ASTM E595 is the global benchmark for evaluating a material's volatile stability. To precisely match the operational realities of ambient microelectronic, medical device, and biopharma facilities, CC Matting underwent specialized ASTM E595 testing modified to a continuous 50°C thermal vacuum exposure.

  • 0.29% Total Mass Loss (TML) Measures weight lost as gases escape. (Standard Limit: ≤ 1.0%max)
  • 0.08% CVCM Collected Volatile Condensable Materials onto a plate. (Standard Limit: ≤ 0.10% max)
  • 0.10% Water Vapor Regained Indicates moisture re-absorption post-test. Proves zero retention.


Future-Proofing Your Cleanroom Integrity

  • Complete Zonal Isolation
Placed at your critical "Grey-to-White" cleanroom airlocks, CC Matting functions as a heavy-duty physical barrier. The supple, high-density polymeric matrix contours completely around shoe treads and trolley wheels, pulling away 99.9% of foot- and wheel-borne particulates through a simple 6-step walk path.

  • Zero Atmospheric Contamination
Because the compound is engineered for absolute molecular stability, it does not degrade, off-gas, or shed microscopic chemical fragments under the constant pull of high-velocity cleanroom air currents. Your air purity remains uncompromised, your sensor readings stay accurate, and your production yields are fully shielded. Ready to audit your cleanroom's environmental defenses?
