3M Ultra-R2 Rubber is a static-safe work surface that is highly resistant to solvents, hot solder, and soldering irons. It is made of a two-layer combination of static dissipative and conductive rubber materials that provide excellent electrical performance.
The document lists 3M's workstation ESD protection products, including Ultra‑R2 two‑layer rubber mats, three‑layer dissipative vinyl mats, homogeneous vinyl mats, and a range of mat kits with different sizes and colors. Each product description includes performance standards, electrical resistance values, thickness, and compatible monitor types.
Technical details such as surface resistance (Rtg), through‑thickness resistance (Rtt), and material thickness are provided for each product variant, along with part numbers for the various sizes and colors. The leaflet also notes the use of green mats to designate lead‑free work areas and offers custom size options on request.
| Surface resistance (Rtg) | 10° ohm |
|---|---|
| Through‑thickness resistance (Rtt) | 10’ ohm |
| Thickness | 0.060 in (1.5 mm) |
They meet ESD Standard 4.1, ESD Standard 20.20, EIA 625, MIL‑HDBK‑263, and MIL‑STD‑1686.
The 24 in. × 36 in. kits are offered in blue (P/N RIM2436L2RBL-L), gray (RM2436L2RGR-L), and green (RM2436L2RGN-L) versions.
Green mats are used to indicate lead‑free work areas.
