ACL Staticide 2440 Dualmat Static Dissipative Mat, 24 in x 40 ft Roll, Multiple Colors Available
The ACL Staticide 2440 Dualmat is the go-to ESD mat roll for electronics manufacturing workstations that need permanent, inherent static dissipation — not a topical treatment that degrades over time. At 24″ × 40 ft, it covers a full production run of standard workbenches and comes with a lifetime electrical warranty.

Frequently Asked Questions
What is the best ESD mat for electronics assembly workstations?
The ACL Staticide Dualmat series is widely used in electronics manufacturing because it is inherently dissipative — the electrical properties are built into the rubber compound, not applied as a surface treatment. This means performance does not degrade with cleaning or age, making it a reliable long-term choice for ANSI/ESD S20.20-compliant EPAs.
What is the difference between a dissipative and conductive ESD mat?
A dissipative mat (10⁶–10⁸ Ω) slows the discharge rate to safely protect sensitive components. A conductive mat (<10⁵ Ω) discharges faster and is used where rapid grounding is required. The Dualmat 2440 combines both: a dissipative top layer for safe component contact and a conductive bottom layer for reliable grounding — giving you the best of both in a single mat.
Does the ACL Staticide 2440 comply with ANSI/ESD S20.20?
Yes. The 2440 Dualmat is fully compliant with ANSI/ESD S20.20 and REACH. It contains no vinyl monomers or DOP, making it suitable for facilities with strict chemical compliance requirements including aerospace, medical device, and defense electronics manufacturing.
How do I ground an ESD mat roll?
Pre-cut mats include two 10mm female snaps for grounding cord attachment. For roll stock, snaps are added during cutting. Connect a standard ESD grounding cord from the mat snap to a verified common point ground. For continuous monitoring, the conductive bottom layer is compatible with workstation monitors that verify both wrist strap and mat ground paths simultaneously.
Can I use the Dualmat with a continuous workstation monitor?
Yes. The conductive bottom layer is compatible with continuous workstation monitors that verify both the wrist strap and mat ground path simultaneously — a requirement for many ANSI/ESD S20.20 audit programs.
How does the Dualmat compare to vinyl ESD mats?
Vinyl mats typically rely on topical treatments or conductive additives that can degrade over time with cleaning and use. The Dualmat uses chemically cross-linked rubber with inherent dissipative properties throughout the material — no surface treatment to wear off. It also resists solvents, heat, and UV degradation better than standard vinyl alternatives.
