Statfree HJ® Textured Dual-Layer Dissipative Rubber Workstation Mat

ESD-Safe Lead-Free

Dissipative dual layer ESD worksurface
Provides a worksurface that does not generate a static charge and will control the discharge rate from all conductors (including ESD susceptible items) that are placed on the surface.
Abrasion resistance rubber compound
Increased hardness (80 to 90 Type A) for greater resistance to abrasion, cuts, stretching and tearing. May be used in soldering applications with flux and other chemicals.
Dissipative (1 x 10⁶ to <1 x 10⁹ ohms Rtt) top layer
Meets ANSI/ESD S20.20 worksurface required limit and recommendation of ANSI/ESD S4.1 for contact with ESD susceptible items.
Conductive (<1 x 10⁶ Rtt) bottom layer - Limited lifetime warranty
Reduces the resistance to ground (Rtg) from the top of the surface to the groundable point ground and allows the material to be used with ESD workstation monitors.
Laser engraved with ESD protective symbol, specs, and manufacturer information
Identifies ESD protective product for control & auditing purposes.
Lead-free RoHS compliant
Made in Japan
