Desco 42540 Statfree Z2 Dissipative 3-Layer Vinyl Roll, Black, 24" x 50' x .125"
Desco 42540 — Statfree Z2 Dissipative 3-Layer Vinyl Roll, Black, 24" × 50' × .125"
The Desco 42540 Statfree Z2 is a heat-fused 3-layer dissipative vinyl roll for ESD-protected workstation bench mats, shelf liners, and cart shelf liners. Black colorway. The .125" thick construction combines an abrasion-resistant dissipative top layer, a highly conductive mesh middle layer for reliable grounding, and a dissipative cushioned bottom layer for energy absorption. All three layers carry a Limited Lifetime Warranty with no electrical drift. The 24" × 50' roll can be cut to any required length. Meets ANSI/ESD S20.20 and ANSI/ESD S4.1 worksurface requirements. Made in the USA.

Key Features
- Heat Fused 3-Layer Vinyl Composite: All three layers are permanently bonded — no delamination. Provides reliable path to ground and eliminates static charge generation as a bench worksurface, shelf liner, or cart liner.
- Dissipative Abrasion-Resistant Top Layer (Limited Lifetime Warranty): Meets ANSI/ESD S20.20 and ANSI/ESD S4.1 requirements. Electricals will not drift for the life of the mat.
- Conductive Mesh Middle Layer (<1×10⁴ Ω, Limited Lifetime Warranty): Highly conductive mesh layer provides a low-resistance path to ground (Rtg) from the top surface to the groundable point. Enables use with ESD workstation continuous monitors. Electricals will not drift for the life of the mat.
- Dissipative Cushioned Bottom Layer (Limited Lifetime Warranty): Absorbs energy to protect ESD-sensitive components susceptible to physical shock. Electricals will not drift for the life of the mat.
- Black Color: Standard production look. For blue colorway in the same 24" × 50' size, see the Desco 42500. For black in the wider 30" width, see the Desco 42558.
- 24" Width × 50' Roll: Standard single-operator bench width. Cut to any required length.
- Multiple Applications: Bench worksurface mat, shelf liner in ESD-protected storage, and cart shelf liner for in-process material handling.
- RoHS Compliant. Made in USA.
Frequently Asked Questions
What is the difference between the Desco 42540 and the Desco 42500?
Both are Statfree Z2 24" × 50' × .125" 3-layer vinyl rolls with identical construction, specifications, and Limited Lifetime Warranty. The only difference is color — the 42540 is black; the 42500 is blue. Choose based on workstation color preference or facility standard.
Can the Z2 mat be used with ESD continuous workstation monitors?
Yes. The conductive mesh middle layer (<1×10⁴ Ω) provides a low-resistance path to ground that meets the resistance requirements for use with ESD continuous workstation monitors.
Does the 42540 include a ground cord?
No. The 42540 is the roll only. A Desco mat ground cord with the appropriate snap or eyelet must be purchased separately to connect the mat to a common point ground at the workstation.
