42540 is a Statfree® Z2™ dissipative vinyl roll material measuring 24 inches wide by 50 feet long in black color, designed to provide a path-to-ground and eliminate static charge generation when used as a worksurface table mat, shelf liner, and cart shelf liner. The mat features a 3-layer heat-fused vinyl composite construction with a thickness of 0.125 inches (3.2 mm), comprising a dissipative top layer, conductive middle layer, and dissipative cushioned bottom layer. The surface resistance (1 × 106 to 1 × 10? ohms Rtt) meets ANSI/ESD S20.20 worksurface requirements, while the conductive middle layer reduces resistance to ground and enables use with ESD workstation continuous monitors. The material exhibits excellent mechanical properties including tensile strength greater than 300 psi, tear strength greater than 80 lbs/inch, and abrasion resistance greater than 750 cycles, with a continuous operating temperature range of -20°F to 140°F. This product is ideal for electronics assembly, component handling, and ESD-sensitive environments where static dissipation and component protection are critical.
