Desco 42500 Statfree Z2 Static Dissipative 3-Layer Vinyl Roll - Blue 24" x 50ft x 0.125"
Desco 42500 — Statfree Z2 Dissipative 3-Layer Vinyl Roll, Blue, 24" × 50' × .125"
The Desco 42500 Statfree Z2 is a dissipative 3-layer vinyl bench mat roll for ESD-protected workstation installations. The .125" thickness provides durable cushioning that protects PCBs and assemblies from surface contact damage. The 24" × 50' roll can be cut to any required bench length. The dissipative top layer safely drains static charges at a controlled rate; the conductive bottom layer provides a reliable ground path. Meets ANSI/ESD S20.20 and IEC 61340-5-1 worksurface requirements. Ground cord sold separately.

Key Features
- 3-Layer Vinyl Construction: Dissipative top layer controls static charge drain rate; conductive middle and bottom layers provide a reliable, low-resistance path to ground.
- .125" Thickness: Thicker than standard rubber bench mats — provides cushioning to protect PCBs, discrete components, and assemblies from bench surface contact.
- 24" Width × 50' Roll: Cut to any required bench length. 24-inch width covers standard single-operator bench depth.
- Blue Color: Professional appearance with good contrast for component visibility during assembly and inspection.
- Chemical Resistant: Vinyl construction withstands common solvents and cleaning agents used in production environments.
- ANSI/ESD S20.20 and IEC 61340-5-1 Compliant.
Frequently Asked Questions
How does the Statfree Z2 vinyl mat differ from the Statfree T2 Plus rubber mat?
The Z2 is a 3-layer vinyl mat at .125" thick — softer and more cushioned, suitable for bench applications where component protection from surface contact is a priority. The T2 Plus is a 2-layer nitrile rubber mat at .060" thick — more chemical resistant, better suited for soldering applications with flux, and preferred where a thinner, more durable surface is needed. Both are ANSI/ESD S20.20 compliant dissipative bench mats.
Does the Desco 42500 include a ground cord?
No. The 42500 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.
Can the Z2 vinyl roll be cut to a custom length?
Yes. The 50-foot roll can be cut to any required bench length with a straight edge and utility knife or mat cutter. Cut edges do not affect ESD performance of the remaining material.
