SCS 770086, Table Mat Roll, Rubber, R3, Gray, 24 in x 50 ft

The SCS 770086 is a 24″ × 50 ft roll of R3 Series dissipative rubber worksurface mat in Gray — the same high-performance nitrile rubber construction as the Light Blue and Green R3 series, offered in gray for facilities that prefer a neutral color or use gray for workstation color-coding programs. It resists solvents, flux, and soldering irons while delivering consistent, humidity-independent electrical performance that meets ANSI/ESD S20.20 worksurface requirements for the life of the mat.

Specifications

Key Features

• Dissipative Top Layer: 1×10⁶ to <1×10⁹ Ω Rtt — meets ANSI/ESD S20.20 worksurface required limit and ANSI/ESD S4.1 recommendation for contact with ESD susceptible items.
• Conductive Black Bottom Layer: Dedicated conductive layer reduces Rtg and allows use with ESD workstation monitors. Electricals will not drift for the life of the mat.
• Non-Humidity Dependent: Nitrile rubber compound delivers consistent electrical performance regardless of ambient humidity — no seasonal variation.
• Soldering Application Ready: Resists abrasion, tearing, flux, and soldering iron contact.
• Compatible with Continuous Workstation Monitors: Conductive bottom layer supports real-time ground path verification.
• Neutral Gray Color: Suits facilities with gray workstation color-coding programs or those preferring a neutral worksurface aesthetic.
• Lot Traceability: Full tracking information for quality control and lifespan documentation.
• RoHS 2 & REACH Compliant: Lead-free, made in the USA.

Frequently Asked Questions

What is the difference between the SCS R3 Gray, Light Blue, and Green mat rolls?

All three colors — Gray (770086–770089), Light Blue (770070–770073), and Green (770081–770084) — are electrically identical. The R3 nitrile rubber compound, two-layer construction, and electrical specifications are the same across all colors. The color choice is purely for visual workstation management, color-coding programs, or facility preference. Gray is a common choice for facilities that prefer a neutral worksurface or use gray to designate specific workstation types.

Is the SCS 770086 compatible with continuous workstation monitors?

Yes. The conductive black bottom layer provides a reliable resistance-to-ground (Rtg) path compatible with continuous workstation monitors verifying both wrist strap and mat ground connections simultaneously — a key requirement for ANSI/ESD S20.20 audit compliance.

Does the SCS R3 mat comply with ANSI/ESD S20.20?

Yes. The 770086 meets the ANSI/ESD S20.20 worksurface required limit, tested per ANSI/ESD STM4.1-2017 and ESD TR53. The top layer resistance (1×10⁶ to <1×10⁹ Ω Rtt) meets both the S20.20 required limit and the ANSI/ESD S4.1 recommendation for contact with ESD susceptible items.

Will the electrical properties of the R3 mat change over time?

No. SCS states that electricals will not drift for the life of the mat on both the top color layer and the conductive black bottom layer. The nitrile rubber compound is inherently dissipative — not surface-treated — so performance is stable across the mat’s service life.

What sizes are available in the SCS R3 Gray series?

The R3 Gray series is available in roll widths of 24″, 30″, 36″, and 48″, all in 50 ft lengths, plus a pre-cut 24″ × 48″ kit with grounding hardware (SCS 770090). The same R3 construction is also available in Light Blue and Green.

Can I use the SCS R3 mat for soldering applications?

Yes. The high-strength nitrile rubber compound is specifically constructed to withstand abrasion, tearing, and use in soldering applications with flux and other chemicals — making it one of the few ESD mat materials suitable for active soldering and rework stations.
