Desco 66330 Statfree UC2 Dissipative Dual Layer Rubber Mat, Sky Blue, 30" x 72" x .080"
Desco 66330 — Statfree UC2 Dissipative Dual Layer Rubber Mat, Sky Blue, 30" × 72" × .080"
The Desco 66330 Statfree UC2 is a cleanroom-grade ESD worksurface mat designed for use in controlled environments. The 30" × 72" mat is cleaned and packaged in a Class 1000 (ISO 6) controlled environment and double bagged to control contamination before transfer to the cleanroom. The .080" thick dual layer construction provides a dissipative top surface and a highly conductive bottom layer for reliable grounding. Includes Desco 14213 ground cord. Meets ANSI/ESD S20.20 worksurface requirements. Made in the USA.

Key Features
- Class 1000 Cleanroom Packaged: Mat is cleaned and packaged in a Class 1000 (ISO 6) controlled environment to remove contamination before use. Double bagged to control contamination of contents before transfer to the cleanroom.
- Dissipative Top Layer: Meets ANSI/ESD S20.20 worksurface required limits and ANSI/ESD S4.1 recommendations. Does not generate static charge; controls discharge rate from ESD-sensitive devices on the surface.
- Highly Conductive Bottom Layer (<1×10⁴ Ω): More conductive than standard T2 Plus bottom layers, providing a lower-resistance path to ground for reduced Rtg from top surface to groundable point. Compatible with ESD continuous workstation monitors.
- High Strength Nitrile Rubber: Designed to withstand abrasion, stretching, and tearing. Suitable for soldering applications with flux and other chemicals.
- UV Stabilizer Additives: Preserves color retention and ESD performance; prevents surface cracking and deterioration over time.
- Includes Desco 14213 Ground Cord: Ready to connect to a common point ground at the workstation.
- RoHS 2 Compliant. Made in USA.
Frequently Asked Questions
What makes the Desco 66330 UC2 different from the standard T2 Plus mats?
The UC2 series is specifically designed for cleanroom applications. Key differences from the T2 Plus: (1) the 66330 is cleaned and packaged in a Class 1000 controlled environment and double bagged for cleanroom transfer; (2) it is .080" thick vs. .060" on most T2 Plus mats; (3) the conductive bottom layer resistance is <1×10⁴ Ω, which is more conductive than the T2 Plus bottom layer (<1×10⁶ Ω); and (4) a ground cord is included.
Is the 66330 mat suitable for ISO Class 6 (Class 1000) cleanrooms?
Yes. The 66330 is cleaned and packaged in a Class 1000 (ISO 6) controlled environment and double bagged to minimize contamination risk during transfer into the cleanroom. Always follow your facility's cleanroom transfer and gowning procedures when introducing new materials.
Does the Desco 66330 include grounding hardware?
Yes. The 66330 includes the Desco 14213 ground cord. Connect it from the mat’s groundable snap to a common point ground at the workstation. Verify grounding with a surface resistance meter after installation.
