- Lifetime Electrical Warranty: Electrical properties warranted for the life of the mat.
- REACH Compliant: No vinyl monomers or DOP — suitable for facilities with strict chemical compliance requirements.
- Static Decay: 0.05 seconds from 5,000V to 50V.
- Embossed Surface: UV color stability additives; protects against parts slippage and UV damage.
- Custom Sizes Available: Pre-cut mats include two 10mm female snaps; custom sizes available on request.
Frequently Asked Questions
What ESD mat is best for large assembly lines and production benches?
The ACL Staticide 4840 Dualmat is the widest standard roll in the Dualmat series at 48″, making it the right choice for oversized workbenches, production line stations, and high-throughput electronics assembly areas. It eliminates the need for side-by-side mat placement and provides a single continuous grounded surface across the full bench width.
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 4840 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 4840 comply with ANSI/ESD S20.20?
Yes. The 4840 Dualmat is fully compliant with ANSI/ESD S20.20 and REACH. It contains no vinyl monomers or DOP, making it suitable for aerospace, medical device, and defense electronics manufacturing facilities with strict chemical compliance requirements.
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. The conductive bottom layer is compatible with continuous 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 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.
